External beam radiotherapy
Once the exact area to be treated has been identified it will be marked with ink. You will need to be circumcised (surgical removal of the foreskin) before radiotherapy to reduce the chance of skin swelling and irritation. Treatment may to be given over a six-week period in short doses (10-15 minutes). Beams of radiation are directed at the cancer and controlled by a computer.
Brachytherapy
This can be used to treat penile cancer which is not greater than 4cm in size. Under general anaesthetic radioactive needles are positioned in the penis and small radioactive pellets inserted near to the cancerous areas. The needles will need to stay in place for up to 7 days and you will have to stay in hospital during this time. Your movement will be limited (bed rest) during this time. Children and pregnant women will not be allowed to visit you. To protect the urethra or water pipe and allow urinary drainage a urinary catheter will be inserted into your bladder. More information about urinary catheters can be found here. The needles and the catheter will be removed under a general anaesthetic once all the treatment has been given.
Plesiobrachytherapy
This is a type of brachytherapy which uses a special plastic mould to cover the penis. Small radioactive wires are attached to the cancerous area of the penis. Radiation can then be given through the wires. This type of treatment is performed on a daily basis for several days.
Side Effects of Radiotherapy
| Skin reactions | Radiotherapy can irritate the skin These symptoms may occur 2-3 weeks after treatment. Vitamin E supplements and topical creams can help the healing process, and these may be prescribed by the healthcare team. It is also advisable to keep areas that have been exposed to radiotherapy covered and protected from direct sunlight. Treated areas may turn a slightly darker colour temporarily.

| Fatigue
|
This may be caused by a combination of treatment and travel. Getting small restful naps or taking a mild sedative medication may help.
|
| Feeling sick (nausea)
|
Anti-sickness medication can be prescribed to help stop nausea. |
| Diarrhoea
|
Reducing your intake of high fibre food may help (fruit, vegetables, wholewheat products). Drinking plenty of fluids will help reduce the risk of dehydration. |
| Lymphoedema | Lymphoedema occurs when lymph fluid accumulates in the groin area and prevents adequate drainage to the lower body (usually the legs and scrotum). This can cause swelling. Lymphoedema is treated by a specialist team of healthcare professionals. For more information on lymphoedema please click here (link to lymphoedema page). |
