Lung cancer

Lung cancer is one of the most common and serious types of cancer. 

There are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms including:

• a persistent cough
• coughing up blood
• persistent breathlessness
• unexplained tiredness and weight loss
• an ache or pain when breathing or coughing

You should speak to your GP if you have these symptoms.

Types of lung cancer

Cancer that begins in the lungs is called primary lung cancer. Cancer that spreads from the lungs to another place in the body is known as secondary lung cancer. This page is about primary lung cancer.

There are 2 main types of primary lung cancer. These are classified by the type of cells in which the cancer starts. They are:

• non-small-cell lung cancer – the most common type, accounting for more than 80% of cases; can be either squamous cell carcinoma, adenocarcinoma or large-cell carcinoma
• small-cell lung cancer – a less common type that usually spreads faster than non-small-cell lung cancer

The type of lung cancer you have determines which treatments are recommended.

Who's affected

Lung cancer mainly affects older people. It's rare in people younger than 40, and the rates of lung cancer rise sharply with age. Lung cancer is most commonly diagnosed in people aged 70 to 74.

Although people who have never smoked can develop lung cancer, smoking is the main cause (accounting for over 85% of cases). This is because smoking involves regularly inhaling a number of different toxic substances.

Treating lung cancer

Treatment depends on the type of cancer, how far it's spread and how good your general health is.

If the condition is diagnosed early and the cancerous cells are confined to a small area, surgery to remove the affected area of lung is usually recommended.

If surgery is unsuitable due to your general health, radiotherapy to destroy the cancerous cells may be recommended instead.

If the cancer has spread too far for surgery or radiotherapy to be effective, chemotherapy is usually used.

Symptoms of lung cancer develop as the condition progresses and there are usually no signs or symptoms in the early stages.

The main symptoms of lung cancer are:

• a cough that doesn’t go away after 2 or 3 weeks
• a long-standing cough that gets worse
• persistent chest infections
• coughing up blood
• an ache or pain when breathing or coughing
• persistent breathlessness
• persistent tiredness or lack of energy
• loss of appetite or unexplained weight loss

Less common symptoms of lung cancer include:

• changes in the appearance of your fingers, such as becoming more curved or their ends becoming larger (this is known as finger clubbing)
• a high temperature (fever) of 38C (100.4F) or above 
• difficulty swallowing or pain when swallowing
• wheezing
• a hoarse voice 
• swelling of your face or neck
• persistent chest or shoulder pain

If you have any of these, you should speak to your GP.

Most cases of lung cancer are caused by smoking, although people who have never smoked can also develop the condition.

Smoking

Smoking cigarettes is the single biggest risk factor for lung cancer. It's responsible for more than 85% of all cases.

Tobacco smoke contains more than 60 different toxic substances, which can lead to the development of cancer. These substances are known to be carcinogenic (cancer-producing).

If you smoke more than 25 cigarettes a day, you are 25 times more likely to get lung cancer than a non-smoker.

While smoking cigarettes is the biggest risk factor, using other types of tobacco products can also increase your risk of developing lung cancer and other types of cancer, such as oesophageal cancer and mouth cancer. These products include:

• cigars
• pipe tobacco
• snuff (a powdered form of tobacco)
• chewing tobacco

Smoking cannabis has also been linked to an increased risk of lung cancer. Most cannabis smokers mix their cannabis with tobacco. While they tend to smoke less than tobacco smokers, they usually inhale more deeply and hold the smoke in their lungs for longer.

It's been estimated that smoking 4 joints (homemade cigarettes mixed with cannabis) may be as damaging to the lungs as smoking 20 cigarettes.

Even smoking cannabis without mixing it with tobacco is potentially dangerous. This is because cannabis also contains substances that can cause cancer.

Passive smoking

If you don't smoke, frequent exposure to other people’s tobacco smoke (passive smoking) can increase your risk of developing lung cancer.

For example, research has found that non-smoking women who share their house with a smoking partner are 25% more likely to develop lung cancer than non-smoking women who live with a non-smoking partner.

Radon

Radon is a naturally occurring radioactive gas that comes from tiny amounts of uranium present in all rocks and soils. It can sometimes be found in buildings.

If radon is breathed in, it can damage your lungs, particularly if you're a smoker. 

Occupational exposure and pollution

Exposure to certain chemicals and substances used in several occupations and industries has been linked to a slightly higher risk of developing lung cancer. These chemicals and substances include:

• arsenic
• asbestos
• beryllium
• cadmium
• coal and coke fumes
• silica
• nickel

Read more information about asbestosis and silicosis.

Research also suggests that being exposed to large amounts of diesel fumes for many years may increase your risk of developing lung cancer by up to 50%. One study has shown that your risk of developing lung cancer increases by about a third if you live in an area with high levels of nitrogen oxide gases (mostly produced by cars and other vehicles).

Speak to your GP if you have symptoms of lung cancer, such as breathlessness or a persistent cough.

Your GP will ask about your general health and what symptoms you've been experiencing. They may examine you and ask you to breathe into a device called a spirometer, which measures how much air you breathe in and out.

You may be asked to have a blood test to rule out some of the possible causes of your symptoms, such as a chest infection.

In 2015, the National Institute for Health and Care Excellence (NICE) published guidelines to help GPs recognise the signs and symptoms of lung cancer and refer people for the right tests faster. To find out if you should be referred for further tests for suspected lung cancer.

Chest X-ray

A chest X-ray is usually the first test used to diagnose lung cancer. Most lung tumours show up on X-rays as a white-grey mass.

However, chest X-rays can't give a definitive diagnosis because they often can't distinguish between cancer and other conditions, such as a lung abscess (a collection of pus that forms in the lungs).

If your chest X-ray suggests you may have lung cancer, you should be referred to a specialist (if you haven't already) in chest conditions such as lung cancer. A specialist can carry out more tests to investigate whether you have lung cancer and, if you do, what type it is and how much it's spread.

CT scan

A computerised tomography (CT) scan is usually carried out after a chest X-ray. A CT scan uses X-rays and a computer to create detailed images of the inside of your body.

Before having a CT scan, you'll be given an injection of a contrast medium. This is a liquid containing a dye that makes the lungs show up more clearly on the scan. The scan is painless and takes 10 to 30 minutes to complete.

PET-CT scan

A PET-CT scan (which stands for positron emission tomography-computerised tomography) may be carried out if the results of the CT scan show you have cancer at an early stage.

The PET-CT scan can show where there are active cancer cells. This can help with diagnosis and treatment.

Before having a PET-CT scan, you'll be injected with a slightly radioactive material. You'll be asked to lie down on a table, which slides into the PET scanner. The scan is painless and takes around 30 to 60 minutes.

Bronchoscopy and biopsy

If the CT scan shows there might be cancer in the central part of your chest, you'll have a bronchoscopy. A bronchoscopy is a procedure that allows a doctor or nurse to remove a small sample of cells from inside your lungs.

During a bronchoscopy, a thin tube called a bronchoscope is used to examine your lungs and take a sample of cells (biopsy). The bronchoscope is passed through your mouth or nose, down your throat and into the airways of your lungs.

The procedure may be uncomfortable, but you'll be given a mild sedative beforehand to help you relax and a local anaesthetic to make your throat numb. The procedure is very quick and only takes a few minutes.

Other types of biopsy

If you're not able to have one of the biopsies described above, or you've had one and the results weren't clear, you may be offered a different type of biopsy. This may be a type of surgical biopsy such as a thoracoscopy or a mediastinoscopy, or a biopsy carried out using a needle inserted through your skin.

Percutaneous needle biopsy

A percutaneous needle biopsy involves removing a sample from a suspected tumour to test it at a laboratory for cancerous cells.

The doctor carrying out the biopsy will use a CT scanner to guide a needle to the site of a suspected tumour through the skin. A local anaesthetic is used to numb the surrounding skin, and the needle is passed through your skin and into your lungs. The needle will then be used to remove a sample of tissue for testing.

Thoracoscopy

A thoracoscopy is a procedure that allows the doctor to examine a particular area of your chest and take tissue and fluid samples.

You're likely to need a general anaesthetic before having a thoracoscopy. Two or three small cuts will be made in your chest to pass a tube (similar to a bronchoscope) into your chest. The doctor will use the tube to look inside your chest and take samples. The samples will then be sent away for tests.

After a thoracoscopy, you may need to stay in hospital overnight while any further fluid in your lungs is drained out.

Mediastinoscopy

A mediastinoscopy allows the doctor to examine the area between your lungs at the centre of your chest (mediastinum).

For this test, you'll need to have a general anaesthetic and stay in hospital for a couple of days. The doctor will make a small cut at the bottom of your neck so they can pass a thin tube into your chest.

The tube has a camera at the end, which enables the doctor to see inside your chest. They'll also be able to take samples of your cells and lymph nodes at the same time. The lymph nodes are tested because they're usually the first place that lung cancer spreads to.

Staging

Once tests have been completed, it should be possible to work out what stage your cancer is, what this means for your treatment and whether it's possible to completely cure the cancer.

Non-small-cell lung cancer

Non-small-cell lung cancer (the most common type) usually spreads more slowly than small-cell lung cancer and responds differently to treatment.

Stage 1

The cancer is contained within the lung and hasn't spread to nearby lymph nodes. Stage 1 can also be divided into two sub-stages:

• stage 1A – the tumour is less than 3cm in size (1.2 inches) 
• stage 1B – the tumour is 3-5cm (1.2-2 inches)

Stage 2

Stage 2 is divided into 2 sub-stages: 2A and 2B.

In stage 2A lung cancer, either:

• the tumour is 5 to 7cm 
• the tumour is less than 5cm and cancerous cells have spread to nearby lymph nodes

In stage 2B lung cancer, either:

• the tumour is larger than 7cm 
• the tumour is 5 to 7cm and cancerous cells have spread to nearby lymph nodes 
• the cancer hasn't spread to lymph nodes, but has spread to surrounding muscles or tissue 
• the cancer has spread to one of the main airways (bronchus) 
• the cancer has caused the lung to collapse 
• there are multiple small tumours in the lung

Stage 3

Stage 3 is divided into 2 sub-stages: 3A and 3B.

In stage 3A lung cancer, the cancer has either spread to the lymph nodes in the middle of the chest or into the surrounding tissue. This can be:

• the covering of the lung (the pleura)
• the chest wall
• the middle of the chest
• other lymph nodes near the affected lung

In stage 3B lung cancer, the cancer has spread to either of the following:

• lymph nodes on either side of the chest, above the collarbones
• another important part of the body, such as the gullet (oesophagus), windpipe (trachea), heart or into a main blood vessel

Stage 4

In stage 4 lung cancer, the cancer has either spread to both lungs or to another part of the body (such as the bones, liver or brain), or the cancer has caused fluid-containing cancer cells to build up around your heart or lungs.

Small-cell lung cancer

Small-cell lung cancer is less common than non-small-cell lung cancer. The cancerous cells responsible for the condition are smaller in size when examined under a microscope than the cells that cause non-small-cell lung cancer.

Small-cell lung cancer only has 2 possible stages:

• limited disease – the cancer has not spread beyond the lung
• extensive disease – the cancer has spread beyond the lung

Read further information:

• Cancer Research UK: Types of lung cancer
• Macmillan Cancer Support: Being diagnosed with lung cancer 

Treatment for lung cancer is carried out by a team of specialists who will work together to provide the best possible treatment.

This team contains all the specialists required to make a proper diagnosis, to stage your cancer and to plan the best treatment. If you want to know more, ask your specialist about this.

The type of treatment you'll receive for lung cancer depends on several factors, including:

• the type of lung cancer you have (non-small-cell or small-cell cancer)
• the size and position of the cancer
• how far advanced your cancer is (the stage)
• your overall health

Deciding what treatment is best for you can be difficult. Your cancer team will make recommendations, but the final decision will be yours.

The main treatment options include surgery, radiotherapy and chemotherapy. Depending on your type of cancer and how advanced it is, you may receive a combination of these treatments.

Your treatment plan

Your treatment plan depends on whether you have non-small-cell lung cancer or small-cell lung cancer.

Non-small-cell lung cancer

If you have non-small-cell lung cancer that's confined to one lung and you're in good general health, you'll probably have surgery to remove the cancerous cells. This may be followed by a course of chemotherapy to destroy any cancer cells that may have remained in the body.

If the cancer hasn't spread too far but surgery isn't possible (for example, if your general health means you have an increased risk of developing complications), radiotherapy to destroy the cancerous cells will usually be recommended. In some cases, this may be combined with chemotherapy (known as chemoradiotherapy).

If the cancer has spread too far for surgery or radiotherapy to be effective, chemotherapy is usually recommended. If the cancer starts to grow again after initial chemotherapy treatment, another course of treatment may be recommended.

In some cases, a treatment called biological or targeted therapy may be recommended as an alternative to chemotherapy, or after chemotherapy. Biological therapies are medications that can control or stop the growth of cancer cells. 

Small-cell lung cancer

Small-cell lung cancer is usually treated with chemotherapy, either on its own or in combination with radiotherapy. This can help to prolong life and relieve symptoms.

Surgery isn't usually used to treat this type of lung cancer. This is because the cancer has often already spread to other areas of the body by the time it's diagnosed. However, if the cancer is found very early, surgery may be used. In these cases, chemotherapy or radiotherapy may be given after surgery to help reduce the risk of the cancer returning.

Surgery

There are 3  types of lung cancer surgery:

• lobectomy – where one or more large parts of the lung (called lobes) are removed – your doctors will suggest this operation if the cancer is just in 1 section of 1 lung
• pneumonectomy – where the entire lung is removed – this is used when the cancer is located in the middle of the lung or has spread throughout the lung
• wedge resection or segmentectomy – where a small piece of the lung is removed (this procedure is only suitable for a small number of patients, as it is only used if your doctors think your cancer is small and limited to one area of the lung – this is usually very early-stage non-small-cell lung cancer)

People are naturally concerned that they won't be able to breathe if some or all of a lung is removed, but it's possible to breathe normally with 1 lung. However, if you have breathing problems before the operation, such as breathlessness, it's likely that these symptoms will continue after surgery.

Tests before surgery

Before surgery can take place, you'll need to have a number of tests to check your general state of health and your lung function. These may include:

• an electrocardiogram (ECG) – electrodes are used to monitor the electrical activity of your heart
• spirometry – you'll breathe into a machine called a spirometer, which measures how much air your lungs can breathe in and out

How it's performed

Surgery is usually performed by making a cut (incision) in your chest or side, and removing a section or all of the affected lung. Nearby lymph nodes may also be removed if it's thought that the cancer may have spread to them.

In some cases, an alternative to this approach, called video-assisted thoracoscopic surgery (VATS), may be suitable. VATS is a type of keyhole surgery, where small incisions are made in the chest. A small fibre-optic camera is inserted into one of the incisions, so the surgeon can see images of the inside of your chest on a monitor.

After the operation

You'll probably be able to go home 5 to 10 days after your operation. However, it can take many weeks to recover fully from a lung operation.

After your operation, you'll be encouraged to start moving about as soon as possible. Even if you have to stay in bed, you'll need to keep doing regular leg movements to help your circulation and prevent blood clots from forming. A physiotherapist will show you breathing exercises to help prevent complications.

When you go home, you'll need to exercise gently to build up your strength and fitness. Walking and swimming are good forms of exercise that are suitable for most people after treatment for lung cancer. Talk to your care team about which types of exercise are suitable for you.

Complications

As with all surgery, lung surgery carries a risk of complications. These are estimated to occur in 1 out in 5 cases. These complications can usually be treated using medication or additional surgery, which may mean you need to stay in hospital for longer.

Complications of lung surgery can include:

• inflammation or infection of the lung (pneumonia) 
• excessive bleeding 
• a blood clot in the leg (deep vein thrombosis), which could potentially travel up to the lung (pulmonary embolism)

Radiotherapy

Radiotherapy is a type of treatment that uses pulses of radiation to destroy cancer cells. There are a number of ways it can be used to treat people with lung cancer.

An intensive course of radiotherapy, known as radical radiotherapy, can be used to try to cure non-small-cell lung cancer if the person isn't healthy enough for surgery. For very small tumours, a special type of radiotherapy called stereotactic radiotherapy may be used instead of surgery.

Radiotherapy can also be used to control the symptoms and slow the spread of cancer when a cure isn't possible (this is known as palliative radiotherapy).

A type of radiotherapy known as prophylactic cranial irradiation (PCI) is also sometimes used during the treatment of small-cell lung cancer. PCI involves treating the whole brain with a low dose of radiation. It's used as a preventative measure because there's a risk that small-cell lung cancer will spread to your brain.

The 3 main ways that radiotherapy can be given are described below:

• conventional external beam radiotherapy – a machine is used to direct beams of radiation at affected parts of your body
• stereotactic radiotherapy – a more accurate type of external beam radiotherapy where several high-energy beams are used to deliver a higher dose of radiation to the tumour, while sparing the surrounding healthy tissue as much as possible
• internal radiotherapy – a catheter (thin tube) is inserted into your lung – a small piece of radioactive material is placed inside the catheter and positioned against the site of the tumour before being removed after a few minutes

For lung cancer, external beam radiotherapy is used more often than internal radiotherapy, particularly if it's thought that a cure is possible. Stereotactic radiotherapy may be used to treat tumours that are very small, as it's more effective than standard radiotherapy alone in these circumstances.

Internal radiotherapy only tends to be used as a palliative treatment when the cancer is blocking or partly blocking your airway.

Courses of treatment

A course of radiotherapy treatment can be planned in several different ways.

Radical radiotherapy is usually given 5 days a week, with a break at weekends. Each session of radiotherapy lasts 10 to 15 minutes and the course usually lasts 4 to 7 weeks.

Continuous hyperfractionated accelerated radiotherapy (CHART) is an alternative method of delivering radical radiotherapy. CHART is given 3 times a day for 12 days in a row.

For stereotactic radiotherapy, fewer treatment sessions are needed because a higher dose of radiation is delivered with each treatment. People having conventional radical radiotherapy are likely to have around 20 to 32 treatment sessions, whereas stereotactic radiotherapy typically only requires anything from 3 to 10 sessions.

Palliative radiotherapy usually only requires 1 to 5 sessions to control your symptoms. 

Side effects

Side effects of radiotherapy to the chest include:

• chest pain 
• fatigue 
• persistent cough that may bring up blood-stained phlegm (this is normal and nothing to worry about) 
• difficulties swallowing (dysphagia) 
• redness and soreness of the skin, which looks and feels like sunburn 
• hair loss on your chest 

Side effects should pass once the course of radiotherapy has been completed.

Chemotherapy

Chemotherapy uses powerful cancer-killing medication to treat cancer. There are several different ways that chemotherapy can be used to treat lung cancer. For example, it can be:

• given before surgery to shrink a tumour, which can increase the chance of successful surgery (this is usually only done as part of a clinical trial)
• given after surgery to prevent the cancer returning 
• used to relieve symptoms and slow the spread of cancer when a cure isn't possible
• combined with radiotherapy

Chemotherapy treatments are usually given in cycles. A cycle involves taking the chemotherapy medication for several days, then having a break for a few weeks to let your body recover from the effects of the treatment.

The number of cycles of chemotherapy you need will depend on the type and the grade of your lung cancer. Most people require four to 6 courses of treatment over 3 to 6 months.

Chemotherapy for lung cancer involves taking a combination of different medications. The medications are usually delivered through a drip into a vein (intravenously), or into a tube connected to one of the blood vessels in your chest. Some people may be given capsules or tablets to swallow instead.

Side effects

Side effects of chemotherapy can include:

• fatigue 
• nausea
• vomiting 
• mouth ulcers
• hair loss

These side effects should gradually pass once your treatment has finished, or you may be able to take other medicines to make you feel better during your chemotherapy.

Chemotherapy can also weaken your immune system, making you more vulnerable to infection. Tell your care team or GP as soon as possible if you have possible signs of an infection, such as a high temperature (fever) of 38C (100.4F) or more, or you suddenly feel generally unwell.

Other treatments

As well as surgery, radiotherapy and chemotherapy, there are a number of other treatments that are sometimes used to treat lung cancer. 

Biological therapies

Biological therapies are newer medications. They're sometimes recommended as an alternative treatment to chemotherapy for non-small-cell cancer that has spread too far for surgery or radiotherapy to be effective.

Examples of biological therapies include erlotinib and gefitinib. These are also called growth factor inhibitors because they work by disrupting the growth of the cancer cells.

Biological therapies are only suitable for people who have certain proteins in their cancerous cells. Your doctor may be able to request tests on a small sample of cells removed from your lung (biopsy) to determine whether these treatments are likely to be suitable for you.

Radiofrequency ablation

Radiofrequency ablation is a new type of treatment that can treat non-small-cell lung cancer diagnosed at an early stage.

The doctor carrying out the treatment uses a computerised tomography (CT) scanner to guide a needle to the site of the tumour. The needle will be pressed into the tumour and radio waves will be sent through the needle. These waves generate heat, which kills the cancer cells.

The most common complication of radiofrequency ablation is that a pocket of air gets trapped between the inner and outer layer of your lungs (pneumothorax). This can be treated by placing a tube into the lungs to drain away the trapped air.

Cryotherapy

Cryotherapy is a treatment that can be used if the cancer starts to block your airways. This is known as endobronchial obstruction, and it can cause symptoms such as:

• breathing problems
• a cough
• coughing up blood

Cryotherapy is performed in a similar way to internal radiotherapy, except that instead of using a radioactive source, a device known as a cryoprobe is placed against the tumour. The cryoprobe can generate very cold temperatures, which help to shrink the tumour.

Photodynamic therapy

Photodynamic therapy (PDT) is a treatment that can be used to treat early-stage lung cancer when a person is unable or unwilling to have surgery. It can also be used to remove a tumour that's blocking the airways.

Photodynamic therapy is carried out in 2 stages. Firstly, you'll be given an injection of a medication that makes the cells in your body very sensitive to light.

The next stage is carried out 24 to 72 hours later. A thin tube will be guided to the site of the tumour, and a laser will be beamed through it. The cancerous cells, which are now more sensitive to light, will be destroyed by the laser beam.

Side effects of photodynamic therapy can include inflammation of the airways and a build-up of fluid in the lungs. Both these side effects can cause symptoms of breathlessness and lung and throat pain. However, these symptoms should gradually pass as your lungs recover from the effects of the treatment.

Breathlessness is common in people who have lung cancer, whether it is a symptom of the condition or a side effect of treatment.

In many cases, breathlessness can be improved with some simple measures such as:

• breathing in slowly through your nose and out through your mouth (after treatment for lung cancer, you may see a physiotherapist, who can teach you some simple breathing exercises)
• making daily activities easier – for example, using a trolley when you go shopping or keeping things you often need downstairs so you don't need to regularly walk up and down the stairs
• using a fan to direct cool air towards your face
• eating smaller and more frequent meals, and taking smaller mouthfuls

If measures like these aren't enough to control your breathlessness, you may need further treatment. There are a number of medications that can help improve breathlessness. Home oxygen treatment may be an option in more severe cases.

If your breathlessness is caused by another condition, such as a chest infection or a fluid build-up around the lungs (a pleural effusion), treating this underlying cause may help your breathing.

Pain

Some people with lung cancer have pain, while others never have any. About 1 in 3 people who are treated for cancer experience some pain.

Pain isn't related to the severity of the cancer – it varies from person to person. What causes cancer pain isn’t thoroughly understood, but there are ways of treating it so the pain can be controlled.

People with advanced lung cancer may need treatment for pain as their cancer progresses. This can be part of palliative care and is often provided by doctors, nurses and other members of the palliative care team. You can have palliative care at home, in hospital, in a hospice or other care centre.

Emotional effects and relationships

Having cancer can lead to a range of emotions. These may include shock, anxiety, relief, sadness and depression.

People deal with serious problems in different ways. It's hard to predict how living with cancer will affect you.

Being open and honest about how you feel and what your family and friends can do to help you may put others at ease. But don't feel shy about telling people that you need some time to yourself, if that's what you need.

Read further information:

• Macmillan: emotional effects

Talk to others

Your GP or specialist nurse may be able to reassure you if you have questions, or you may find it helpful to talk to a trained counsellor, psychologist or specialist phone helpline. Your GP practice will have information on these.

You may find it helpful to talk about your experience of lung cancer with others in a similar position at a local support group. Patient organisations have local groups where you can meet other people who have been diagnosed with lung cancer and had treatment.

If you have feelings of depression, talk to your GP – they can provide advice and support.

Read further information:

• The Roy Castle Lung Cancer Foundation: Lung cancer support groups
• Macmillan Cancer Support: Depression 

Money and financial support

If you have to reduce or stop work because of cancer, you may find it hard to cope financially. If you have cancer or you're caring for someone with cancer, you may be entitled to financial support.

If you have a job but can't work because of your illness, you are entitled to Statutory Sick Pay from your employer.

If you don't have a job and can't work because of your illness, you may be entitled to Employment and Support Allowance.

If you're caring for someone with cancer, you may be entitled to Carer’s Allowance.

You may be eligible for other benefits if you have children living at home or you have a low household income.

It's a good idea to find out early on what help is available to you. You could ask to speak to the social worker at your hospital, who can give you the information you need.

Read further information:

• GOV.UK: Carers and disability benefits.
• Macmillan Cancer Support: Financial issues 

Palliative care

If you have a lot of symptoms caused by lung cancer, your GP and healthcare team will need to give you support and pain relief. This is called palliative care. Support is also available for your family and friends.

As your cancer progresses, your doctor should work with you to establish a clear management plan based on your (and your carer's) wishes. This includes whether you'd prefer to go to hospital, a hospice, or be looked after at home as you become progressively more ill.

It will take account of what services are available to you locally, what's clinically advisable and your personal circumstances.

If you smoke, the best way to prevent lung cancer and other serious conditions is to stop smoking as soon as possible.

However long you have been smoking, it's always worth quitting. Every year you don't smoke decreases your risk of getting serious illnesses, such as lung cancer. After 10 years of not smoking, your chances of developing lung cancer falls to half that of someone who smokes. Quit Your Way Scotland can offer advice and encouragement to help you quit smoking. 

Your GP or pharmacist can also give you help and advice about giving up smoking.

Diet

Research suggests that eating a low-fat, high-fibre diet, including at least 5 portions a day of fresh fruit and vegetables and plenty of whole grains, can reduce your risk of lung cancer, as well as other types of cancer and heart disease.

More about eating well

Exercise

There's strong evidence to suggest that regular exercise can lower the risk of developing lung cancer and other types of cancer.

Adults should do at least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity each week.
