Chemotherapy drugs can cause unpleasant side effects, but these can usually be well controlled with medicines. Not all drugs cause the same side effects and some people may have very few side effects. Your doctor will tell you about any problems that your treatment may cause.
Lowered resistance to infections
While the drugs are acting on the cancer cells in your body, they also temporarily reduce the number of normal white cells in your blood. When these cells are reduced, you are more likely to get an infection and you may tire easily. During chemotherapy your blood will be tested regularly and, if necessary, you may be given antibiotics to treat any infection.
If your temperature goes above 38°C (100.5°F), or you suddenly feel unwell, even with a normal temperature, you may have an infection. Contact your chemotherapy nurse or doctor at the hospital straight away.
Anaemia
Chemotherapy may reduce the number of red blood cells (haemoglobin) in your blood; a low level of red blood cells is known as anaemia. If you have anaemia, you will probably feel very tired and lethargic. You may also become breathless.
Anaemia can be very successfully treated with blood transfusions. This should help you to feel more energetic and ease the breathlessness.
Bruising and bleeding
Platelets are a type of blood cell which help to clot the blood. If the number of platelets in your blood is low you will bruise very easily and may bleed heavily from even minor cuts or grazes. If you develop any unexplained bruising or bleeding, contact your doctor or the hospital immediately. We have separate information about platelet transfusions.
Feeling sick
Some of the drugs used to treat testicular cancer can make you feel or be sick (nausea and vomiting), but there are very effective anti-sickness drugs (anti-emetics) to prevent this. It is helpful to avoid eating immediately before and after your chemotherapy. If the sickness is not controlled or continues, even with anti-sickness treatment, let your doctor know. They can prescribe other medicines that may be more effective.
Tiredness
Chemotherapy affects people in different ways. Some people find they are able to lead a fairly normal life during treatment, but many find they have to take things much more slowly. Tiredness can build up over a course of treatment, and if you have a lot of chemotherapy, it can last for several months or more after your treatment has finished. It is best to cope with tiredness by planning ahead. Try to fit in rest periods and don’t do things that you don’t need to do. Accept help from others when you need to. There may be times when you feel less tired. A little activity can sometimes help with the symptoms of fatigue.
Sore mouth and loss of appetite
Some chemotherapy drugs can make your mouth sore and cause small ulcers. It is important to rinse your mouth regularly to keep it clean. Using a child’s soft toothbrush can be helpful. If you don't feel like eating during treatment, you could try replacing some meals with nutritious drinks or a soft diet.
Hair loss
Unfortunately, some chemotherapy drugs will make your hair fall out. People who lose their hair often cover up by wearing wigs, bandanas, hats or scarves. If you are being treated as an inpatient, or you are on income support, you can get a free wig from the NHS. If not, you can still get a subsidised wig from the hospital. Ask the team looking after you if a wig specialist is available to visit you. If your hair falls out it is important to protect your scalp from the sun. If you lose your hair it will start to grow back within three to six months of finishing your treatment.
Breathlessness
The chemotherapy drug bleomycin can occasionally cause inflammation in the lungs and this can lead to breathlessness. This is usually mild, but if it becomes a problem your doctor may stop or change the drug. After having bleomycin you may not be able to take part in certain activities, such as sub-aqua diving. If you need to have an operation after having bleomycin, you should always tell the anaesthetist that you have had bleomycin treatment.
Hearing changes
Another drug, cisplatin, can cause tinnitus (ringing in the ears) and you may lose the ability to hear some high-pitched sounds. This usually improves when treatment ends. Let your doctor know if you have any problems with your hearing. They may want to send you for a hearing test.
Peripheral neuropathy
You may also notice numbness or tingling in your hands and feet or difficulty doing up buttons. Your hands and feet may also become more sensitive to the cold. This is due to the effect of the drug on the nerves and is known as peripheral neuropathy. Let your doctor know if this is a problem for you.
Change in kidney function
Chemotherapy can cause changes in the way that your kidneys work so you will have regular blood tests to see how well your kidneys are working.
Although they may be hard to deal with at the time, these side effects will gradually disappear once your treatment is over.
