Living with lung cancer
If you are more breathless than usual you might have a chest infection. Other symptoms include:
coughing up coloured phlegm
a high temperature
People with lung cancer can be more prone to infections. Contact your GP or specialist nurse. You might need a course of antibiotics to clear up the infection. Then your breathing will be easier.
If you are very anxious, this can make you feel more breathless. This can be very frightening and make you feel even more anxious.
If you feel panicky, try to slow your breathing down. Concentrate on breathing in and out slowly.
You can practise using breathing exercises so that you are confident about using them when you need to.
You can also learn relaxation techniques. There are online resources or books available. Some support groups can lend you books and other resources. Or you might be able to borrow some from your local library.
Red blood cells are made in your bone marrow. They contain haemoglobin (Hb) which carries oxygen around your body. When the level of haemoglobin in your blood is low, you have anaemia.
Anaemia makes you very tired. You may also become breathless because your blood is carrying less oxygen.
Anaemia could be due to the cancer or a treatment such as chemotherapy.
Some breathlessness is normal after lung surgery. This depends on the type of operation you have had and how fit and well you normally are. If you had breathing problems before the operation, you might still have some problems afterwards.
While some people find that their breathing improves as they recover, others might have long term problems. Talk to your doctor about ways to manage this. You could ask to be referred to a breathlessness clinic.
The pleura or pleural membranes are 2 fibrous sheets of tissue. They cover the lungs and help to protect them. Lung cancer can sometimes cause a build up of fluid between the pleura. This is called a pleural effusion. The fluid stops your lungs from expanding fully, causing breathlessness.
You can have treatment to remove some of the fluid, or to stop fluid from building up. This can help relieve symptoms.

Muscles that help with breathing can become weaker in some people with lung cancer. This is often because of a condition called cachexia. Cachexia is a complex change in the body, causing you to lose muscle and often fat.
If a lung cancer partly blocks your airway, it can make it hard to breathe.
Your doctor might suggest that you have a tube called a stent put into the airway to keep it open. This can help you to breathe more easily. They might also treat it with heat to destroy the cancer (thermal ablation).

Lung cancer that grows into the layers covering the heart can cause fluid to build up. This build up is called a pericardial effusion. It affects how well the heart works and can cause breathlessness.
Treatment might involve draining the fluid. Your doctor might also suggest other treatments.
Radiotherapy to the chest area might cause some inflammation of your lungs. Soon after treatment, you might have a dry cough or shortness of breath. This is called acute radiation pneumonitis (pronounced new-mon-eye-tiss).
In a small number of people, a cough and breathlessness can continue. This is because of changes in the lung tissue called chronic radiation pneumonitis. It might start many months or a few years after treatment.
Some types of chemotherapy, immunotherapy or targeted drugs used to treat lung cancer can cause changes to the lung tissue. This is rare, but it might cause breathlessness. Your doctor will suggest ways of managing it.
When you are breathless you might find that you breathe faster and your shoulders tense up.
You may feel that this helps you in the short term. But over a long period, it can make it harder and more tiring for you to breathe.
There are several ways of breathing that you can learn to help with breathlessness. They include:
Relaxed tummy breathing is also known as breathing control. It helps you to change your breathing from fast, upper chest breathing to relaxed, slow tummy breathing.
Breathing from the tummy does not come naturally. Practise this method when you are not breathless. Do it for 10 minutes at a time, at least twice a day.
Relaxed tummy breathing can help you to:
recover quicker if you’re breathless after an activity
settle your breathing if you feel panicky
Use a handheld fan pointed towards your nose, mouth and cheeks.
Make sure you are in a comfortable position. Make sure your head and back are supported. Relax your shoulders and upper chest.
Place one hand on your tummy. Feel your tummy rise and expand as you breathe in and relax down as you breathe out.
Breathe gently when practising.
‘Breathe low and slow, relax, let go’. Take slower, deeper breaths from your tummy instead of small, fast breaths from the top of your chest. This can help to ease breathlessness.
Breathe a rectangle. Some people use the image of a rectangle. This can be a book, a TV, a computer screen, a door, a window, a tabletop, or even a picture on the wall. Follow the sides of the rectangle with your eyes while you tummy breathe. Gradually slow the speed at which your eyes move around the edge of the shape to slow your breathing.
Recovery breathing can help when you feel very breathless or panicky and you are unable to use relaxed tummy breathing.
This method allows more time for the air to leave your lungs as you breathe out. By doing this, you create more room for the next breath in. Recovery breathing helps to calm your breathing until you can breathe smoothly and quietly from your tummy again.
Use a fan to blow cool air across your face.
Support yourself in a ‘forward lean position’. For example, stand at a kitchen counter and rest with your arms on the counter while leaning forward.
Focus on long or relaxed breaths out.
Some people find breathing in through the nose and out through narrowed lips helps with their breathlessness.
Pursed lips breathing helps to support the airways to open. It helps the air to leave the lungs more easily. This creates more room for the next breath in. You can use pursed lips breathing at the same time as relaxed tummy breathing or recovery breathing.

Walking around and going up stairs can be easier if you can control your breathing.
Take your time and avoid rushing. Try matching your breathing with the steps you take. For example, take a breath in and out on each step when climbing the stairs.
Avoid holding your breath when climbing stairs or bending over. Try to ‘blow as you go’ instead. This means breathing out on effort. For example, blow out when standing up from a chair.
You can help yourself by thinking ahead. Make sure the things you need at home during the day are easy to get to. And think about what you are going to do beforehand.
Here are some ideas you can try out:
Move everything you need downstairs to avoid unnecessary trips up and down.
Use a cordless phone or a mobile phone.
Try using a trolley or bag on wheels to carry shopping or washing around.
For household tasks, plan ahead and get everything you need together before you start.
Pace yourself and allow rest times – you will get more done if you don't take on too much at once.
Position a fan where it can blow a stream of cool air across your face. This can help to reduce breathlessness. You can also use a handheld portable fan.
Chewing and swallowing can be difficult if you are feeling breathless.
Try some of the following tips:
Have lots of small meals instead of a few large ones.
Take smaller mouthfuls.
Avoid foods that are difficult to chew.
Keep a drink close by to sip through the day.
Remember that you can lose a lot of fluid in your breath, especially if you are breathing through your mouth. Make sure that you drink plenty of fluids. Being dehydrated can make your saliva and phlegm sticky. Thick saliva can make it difficult to chew and swallow.
Many hospitals have specialist clinics for people who have breathing problems. Ask your healthcare team to refer you to one in your area.
Staff in the clinic can teach you breathing techniques and much more about coping with breathlessness. If there isn't a special clinic, you could have a chat with a physiotherapist or nurse who specialises in helping people with breathing.
Talking things through may help you to solve a few problems.
If you are very breathless you can have oxygen tanks brought to you at home.

Lung cancer starts in the windpipe (trachea), the main airway (bronchus) or the lung tissue. Cancer that starts in the lung is called primary lung cancer.
There is support available during and after treatment to help you cope. This includes support from your clinical nurse specialist, cancer charities, community services, and family and friends.
Your treatment depends on several factors. These include what type of lung cancer you have, how big it is and whether it has spread (the stage). It also depends on your general health.
There are support organisations and resources available for people living with lung cancer.
