Side effects of lung cancer chemotherapy

Chemotherapy drugs affect people in different ways. The side effects vary from person to person. Some people have few side effects and others have more.

Low blood cell levels

Chemotherapy can lower the number of healthy blood cells you have. You may be more tired than usual and have bleeding problems, such as nose bleeds. It can also mean you are more likely to get infections. It is very important to contact the hospital straight away if you think you have an infection, or if you have a temperature of 38°C or higher. Your nurse will give you an emergency telephone number to contact the hospital if this happens.

Other side effects

  • Feeling or being sick and diarrhoea are quite common chemotherapy side effects – you can have medicines to help
  • Hair loss or hair thinning happens with some chemotherapy drugs, but not all – your hair will grow back when the treatment is over
  • You may have mouth ulcers or a sore mouth – regular mouthwashes can help to prevent infection
  • Feeling tired and run down – some people feel very tired during and after chemotherapy. Try to take things more slowly if you need to

Why you get side effects

Chemotherapy drugs kill cells that are dividing. Cancer cells divide more often than normal cells. But some normal body cells also divide quickly and so are also affected by chemotherapy. Quickly dividing cells include those in your skin, hair, nails, the lining of your digestive system, and your blood cells. Unlike cancer cells, these normal body tissues can recover. So you usually have a couple of weeks break between treatments. The break allows your normal body tissues to get over the effects of the chemotherapy.

Chemotherapy affects different people in different ways. Your doctor or chemotherapy nurse can tell you what may happen. But they can't tell beforehand exactly what treatment will be like for you. It isn't something you can easily predict. Side effects are worse for some people than others. 

Many people can go on with their normal lives during their treatment and some can even carry on working. Other people find that they are very tired and have to take things more slowly. Side effects may seem hard to bear at the time. But most disappear when your treatment ends.

Remember that different chemotherapy drugs cause different side effects. There is detailed information about the side effects of specific drugs in the cancer treatment section.

This page gives information about the common side effects of lung cancer chemotherapy.

 

Low blood cell levels

Chemotherapy can lower the number of healthy white blood cells, red blood cells and platelets you have. This can mean that you

  • Are more likely to get infections
  • May be more tired than usual
  • Can be prone to nosebleeds and other bleeding problems

If you develop a temperature above 38°C or think you have an infection, it is very important to contact the hospital immediately. You may need urgent treatment with antibiotics. Your doctor or chemotherapy nurse will give you an emergency number to phone if this happens.

It isn't practical to try to avoid all germs while you are having chemotherapy. But it is important to keep away from anyone you know who has an infection. Avoid crowded, cramped places such as public transport.

We have information on this website about the effect of chemotherapy on your blood cells.

 

Feeling tired and run down

Some people are able to carry on with many of their normal activities when they are having chemotherapy. But many others become very tired. The further through your course of chemotherapy treatment you are, the more likely you are to feel tired and run down. If this is happening to you, try to take things more slowly. If you feel like having a lie down or putting your feet up, then it can help to do that.

Other people are usually very willing to do some things for you so that you can rest if you need to.Family members or friends can often help with household jobs or shopping. The tiredness may last for some months after your treatment has ended. How quickly you get back to normal will depend on 

  • Your general health
  • The amount of treatment you've had
  • Any other treatments you have had

We have detailed information and some helpful tips on coping with tiredness

 

Feeling sick

Sickness is a common chemotherapy side effect. Some drugs only make you feel mildly sick. Others can make some people vomit a lot and feel very sick. There is a page about coping with sickness in the cancer drugs side effects section. Nausea and sickness can now usually be well controlled with anti sickness drugs. Tell your doctor or chemotherapy nurse if you feel sick. You can have other anti sickness medicines, which may suit you better.

 

Taste changes

Some chemotherapy drugs can affect your sense of taste. Foods may taste metallic, salty or bitter, or may not taste of anything. These changes should go away after your treatment ends. We have information about coping with taste changes.

 

Sore mouth and mouth ulcers

Some chemotherapy drugs cause mouth ulcers or soreness in the mouth. To try to prevent infection, it is important to keep your mouth clean. It is best to use a very soft (or baby) toothbrush to avoid damaging the lining of your mouth. If you are likely to get a sore mouth, your nurse will give you mouthwashes to use regularly to help prevent infection. If the soreness gets very bad, you may need painkillers until it has healed. 

We have more information and some helpful tips for coping with a sore mouth in the chemotherapy side effects section.

 

Diarrhoea

Some chemotherapy drugs cause diarrhoea. This can be mild or more severe. If you have diarrhoea for more than 2 or 3 days, you must tell your doctor or nurse. You could become dehydrated, and may need to have anti diarrhoea tablets or medicines.

Your doctor or specialist nurse can give you advice about what to eat or drink if you have diarrhoea. You may also find our information about coping with diarrhoea helpful.

 

Hair loss or thinning

Some chemotherapy drugs cause complete hair loss. Others may cause hair thinning. Some don't cause hair loss at all. 

If you do have hair loss, the hair usually starts to fall out about 2 to 3 weeks after the chemotherapy begins. It will grow back once the treatment is over. Ask your doctor or nurse whether you are likely to lose your hair. Then you can plan how to cope with this. 

Many people wear hats, scarves or wigs. It can be less upsetting to cut your hair short before it starts to fall out. Or you can even have your head shaved, if you know you are going to lose your hair. Find out about getting a free wig on the NHS. Ask your doctor or nurse about it as soon as you know you will have chemotherapy. It can take some time to arrange and you have to be an inpatient when it is ordered and collected.

We have a page about coping with hair loss due to chemotherapy.

 

Eye changes

Some chemotherapy drugs may affect your eyes or your eyesight. Usually the effects are temporary and will go away when you stop taking the drug. But some effects may be long term. Eye changes may include changes to your eyesight, such as blurred vision or dulled vision. Or you may have dry, sore eyes or watery eyes.

You can read about how to cope with eye changes on our page about your eyes and cancer drugs.

 

Hearing changes

Some chemotherapy drugs for lung cancer cause ringing in the ears (tinnitus). You may also find that you can't hear some high pitched sounds. Some people also feel dizzy and lose their sense of balance. Let your doctor or nurse know if you have any change in your hearing or if you feel dizzy.
