Other physical side effects

Prostate cancer and its treatment can affect your body and physical health. All treatments for prostate cancer cause short-term of long-term side effects. In many cases these side effects can be treated, improved or managed.

There are lots of ways to get support for physical side effects: let your doctor and nurse know, and if they can't help then they can refer you to other services, even if it has been a while since you had treatment for prostate cancer. You can also call our confidential Helpline and speak to a specialist nurse.

Tiredness (fatigue)

All treatments for prostate cancer can cause tiredness (fatigue). This can be during and after treatment. Your tiredness could improve after your treatment has finished. How tired you feel during and after treatment will vary. Some men find their tiredness is more long-lasting. Hormone therapy in particular can cause extreme tiredness. Men who have prostate cancer that has spread to other parts of the body (advanced prostate cancer) are also more likely to feel tired.

But tiredness can affect your energy levels, your motivation, ability to concentrate and your emotions. It can be difficult to deal with, especially if you are used to being very active - but there are things that can help.

Where can I get help?

Let your doctor or nurse know how you feel and how tiredness is affecting you. They can check what is causing it and look for ways to help you. Tiredness may be due to your treatment but it can also have other causes such as the cancer itself or other conditions.

If you have extreme tiredness as a result of prostate cancer and treatments, our Get back on track service could help you manage your fatigue so you can do the things you want to do. It's a ten-week telephone service delivered by our Specialist Nurses. Call our Specialist Nurses on 0800 074 8383 to find out whether the service is likely to help you.

What else can help?

Sort out your daily routine, prioritise important tasks and make time for rest.

Gentle exercise such as walking or swimming can help to reduce tiredness. Speak to your doctor before starting any exercise programme.

If you are struggling to eat enough and have lost weight, this may be adding to your tiredness. Ask your GP or specialist team to refer you to a dietitian for advice about your diet. Get more information and diet and physical activity.

If you're finding it hard to get to sleep you could tryrelaxation techniques and dealing with any worries that are keeping you awake. In some cases, men take medicines to help with their sleep, speak to your GP about this.

Get support if you are feeling depressed or anxious, as this can be related to tiredness in people with cancer.

Some research shows that some alternative therapies can help people with cancer manage tiredness. These types of therapies include: acupuncture, breathing control, muscle relaxation, massage, yoga and different types of meditation.

Bowel problems

Radiotherapy for prostate cancer (external beam radiotherapy and brachytherapy) can cause bowel problems for some men. Radiation can cause the lining of the bowel to become inflamed (proctitis) which then leads to symptoms such as loose and watery stools (diarrhoea), pain in the stomach area (abdomen) or back passage, or, more rarely, bleeding from the back passage. Some men find that changes to their bowel habits last for a short time or they can change permanently. Some men develop bowel problems months or years after treatment.

What can help?

Let your doctor or nurse know about any changes in your bowel habits. There are medicines available that can help with symptoms and control diarrhoea.

If you have long term bowel problems, ask to be referred to a bowel specialist (gastroenterologist). You may have a further test to check for any damage to the bowel.

Self-management of bowel problems

  • Try to follow a normal diet and drink plenty of fluids.
  • Although a diet high in fibre such as fruit and vegetables is generally healthy, some men find that too much fibre makes diarrhoea and wind worse.
  • Eating a low fibre diet for a short time may help with these symptoms. Low fibre foods include rice, potatoes (without skins), pasta and meat.
  • Some men find that gentle exercise, such as regular walks, can help with bowel problems after radiotherapy.

Macmillan Cancer Support and the Bladder and Bowel Foundation produce detailed information about coping with bowel problems.
