Radiotherapy for invasive bladder cancer
Radiotherapy uses high energy rays to kill cancer cells. Your specialist may suggest radiotherapy instead of surgery if you want to try to keep your bladder, or try to keep your ability to have an erection. If your cancer comes back in your bladder after radiotherapy, your doctor will probably recommend that you have your bladder removed (cystectomy).
Having your treatment
You have radiotherapy in the hospital radiotherapy department. Treatments are usually once a day, from Monday to Friday, for up to 6 or 7 weeks. Each treatment only takes a few minutes. You may have chemotherapy at the same time (concomitant chemoradiation). Or you may have chemotherapy before the radiotherapy.
Radiotherapy generally causes tiredness and sore, red skin in the treated area. It can also irritate the bladder and bowel. This can cause a need to pass urine very often, pain when passing urine and bowel problems, usually diarrhoea. Drinking plenty of water will help with bladder symptoms. Your doctor or nurse may be able to give you anti diarrhoea tablets.
Side effects usually last a few weeks after your treatment is over. A few people have long term side effects. Radiotherapy for bladder cancer can also affect your ability to have children (fertility). There is information about how radiotherapy affects sex and fertility in the radiotherapy side effects section.
You can view and print the quick guides for all the pages in the Treating bladder cancer section.
For many people with invasive bladder cancer, radiotherapy works as well as surgery at curing it. You may have chemotherapy at the same time as the radiotherapy. This is called concommitant chemoradiation. Or sometimes you may have chemotherapy before starting the radiotherapy course.
But radiotherapy is not recommended if
- You have squamous cell bladder cancer
- You have CIS in much of the bladder lining as well as invasive cancer
- Your cancer does not respond to initial chemotherapy
- Both of the tubes that take urine from the kidneys into the bladder (ureters) are blocked
If you have radiotherapy, you don't need to have your bladder removed and it causes less damage to nerves in the genital area. So this may have less effect on your sexual function. But, radiotherapy can cause short term and long term side effects for some people.
You have radiotherapy treatment in the hospital radiotherapy department. Usually, treatments are once a day, from Monday to Friday, with a rest at the weekend. Radiotherapy to cure bladder cancer can be quite a long course. It may be up to 6 or 7 weeks. The exact dose and length of treatment will need to be decided by your own doctor.
Before you begin your treatment, the radiotherapy team carefully plan your external beam radiotherapy. This means working out how much radiation you need to treat the cancer and exactly where you need it. Your planning appointment may take from 15 minutes up to a couple of hours. You will have a planning CT scan. The scan shows the cancer and the structures around it.
The 360° photo is of a CT scanner. Use the arrows to look around the room.
You lie on the scanner couch with the treatment area exposed. The radiographers will put some markers on your skin. You need to lie very still. Once you are in position the radiographers move the couch up and through the scanner. The scanner is a doughnut shape. The radiographers leave the room and the scan starts. It takes up to 5 minutes. You won't feel anything. The radiographers watch from the next door room.
Once the treatment team has planned your radiotherapy, they may put ink marks on your skin to make sure they treat exactly the same area every day. They may also make pin point sized tattoo marks in these areas. We have information about radiotherapy skin markings.
After your planning session
You may have to wait a few days or up to 2 weeks before you start treatment. During this time the physicists and your radiotherapy doctor decide the final details of your plan. Your doctor will plan the areas that need treatment and outline areas to limit the dose to or avoid completely. They call this contouring. Then the physicists and staff called dosimetrists plan the treatment very precisely using advanced computers.
Radiotherapy machines are very big. The machine may be fixed in one position or able to rotate around your body to give treatment from different directions. Before your first treatment your radiographers will explain what you will see and hear. The treatment rooms usually have docks for you to plug in music players. So you can listen to your own music.
You can't feel radiotherapy when you actually have the treatment. It takes anything from 1 minute to several minutes. It is important to lie in the same position each time, so the radiographers may take a little while to get you ready.
Once you are in the right position the staff leave you alone in the room for a few minutes. They watch you carefully through a window or on a closed circuit television screen. They may ask you to hold your breath or take shallow breaths during the treatment.
Our page about having external radiotherapy has a video about having radiotherapy that you may want to watch.
Radiotherapy doesn't make you radioactive. It is perfectly safe to be with other people, including children, throughout your treatment course.
Look at the main radiotherapy section for more information about radiotherapy and side effects. There is a section about stomach and abdominal side effects of radiotherapy that you may find helpful.
Generally, radiotherapy causes tiredness and sore, red skin in the treated area. When you have it for bladder cancer, radiotherapy can irritate the bladder and nearby bowel and cause particular symptoms. These are
- Pain passing urine
- The need to pass urine very often
- Bowel disturbances, usually diarrhoea
You may feel as if you have cystitis (bladder inflammation). Try to drink plenty of fluids as this will help. The symptoms will gradually get better on their own within a few weeks of your treatment finishing. But you should tell your doctor or radiographer about them in case you have an infection that needs antibiotic treatment.
If you have diarrhoea your nurse or radiographer can give you anti diarrhoea tablets, such as loperamide or codeine. We have information about managing diarrhoea.
Side effects usually last for some weeks after your treatment is over. Tiredness can last for some months, but will gradually wear off. You may find that the radiotherapy may have some short or long term effects on your sex life. You can read about these in the sex, sexuality and cancer section.
A year or two after their radiotherapy treatment, some people develop permanent side effects. You may find that
- Your bladder shrinks slightly, so you need to pass urine more often (this is rare)
- You have blood in your urine
- You have damage to the bowel
You may have blood in your urine because small blood vessels can grow on the surface of the bladder. This is called telangiectasia. Having blood in your urine can be very worrying. You may think it is the cancer coming back. You must tell your doctor or nurse straight away so that you can have a check up and rule that out. If the bleeding is caused by the radiotherapy, it is usually only slight and is nothing to worry about.
Long term bowel damage is uncommon but usually causes diarrhoea. Symptoms are generally mild but occasionally people need to have further treatment.
Most people do not have bad side effects and find their bladder works well after radiotherapy.
Because the bladder is near the reproductive organs, radiotherapy to this area usually means that you can no longer have children after treatment. Men may have lowered sperm counts. Women who have not yet had their menopause may find that they have an early menopause due to the effect of the radiation on the ovaries. If you are worried about this, talk to your radiotherapy specialist before your treatment begins.
There is information about how radiotherapy affects sex and fertility for men and women in the radiotherapy side effects section.
The cancer comes back in the bladder lining in 40 to 50% of people who have radiotherapy. If your cancer comes back and hasn't spread anywhere else in the body, your doctor will probably then recommend that you have your bladder removed (cystectomy). The aim of this treatment is to try to cure your cancer. There is information about surgery for invasive bladder cancer in this section.
