Is radiation therapy right for me ?

Radiation therapy is one of the main treatments offered to men with prostate cancer.

External beam radiation therapy

External beam radiation therapy is used to treat prostate cancer using high intensity radiation beams such as X-rays, gamma rays and electrons. More precisely, it consists in the emission of radiation from an external source directed towards the tumour and some surrounding tissue.

This treatment destroys cancer cells and prevents them from dividing and growing.

Since radiation therapy also reaches healthy cells, radiation oncologists generally divide the treatment into small doses administered five times a week. This allows good cells to regenerate. Each session lasts about 15 minutes and the full treatment program can take 6 to 8 weeks.

External radiation therapy can be used alone or combined with hormonal therapy. It also be administered following radical prostatectomy to reduce the risk of recurrence of the cancer.


Brachytherapy is an internal radiation therapy consisting of inserting radioactive materials directly in the prostate. The main advantage of this treatment is that it allows the administration of a high dose of radiation to the prostate while sparing the surrounding organs.

With this treatment, the radioactive implants are inserted into the prostate during surgery. Over time, the radioactive materials gradually kill cancer cells. The implants can be temporary or permanent.

Brachytherapy is mainly used for patients with low-risk and intermediate-risk prostate cancer. External beam radiation therapy can be combined to brachytherapy for patients with a more aggressive prostate cancer.
