Therapy for prostate cancer usually involves hormone therapy. This is followed by certain side effects. Depending on the hormone used in therapy, some side effects can vary, but in general, they are the same.

Side Effects

At the beginning of hormone therapy for prostate cancer, side effects involve impotence, sweating, hot flushes, breast tenderness etc.


Impotence or erectile dysfunction represents inability to get an erection. It frequently occurs in prostate cancer patient due to hormone therapy, particularly when therapy includes goserelin, leuprorelin or buserelin. During this treatment men don’t produce testosterone. Erection can be regained from 3 to 12 months after cessation of treatment. When therapy consists of only anti androgens, such as bicalutamde, men have 50 % chance of maintaining their erection and libido.

Sweating and Hot FlushesSweating and hot flushes are very unpleasant side effects of hormone therapy. These symptoms are also associated to menopause. When hormone therapy begins, testosterone level starts to decrease and cause hot flushes. This symptom might be better when body adapts to therapy or it can be relieved with progestogens hormones. It is believed that venlafaxine, medication for depression, can assist with hot flushes. Researchers recently evaluated efectiveness of venlafaxin, Cyproterone and Medroxyprogesterone in treatment for hot flushes. They concluded that venlafaxine doesn’t reduce hot flushes frequency as other two drugs and Medroxyprogesteron is recommended as the best therapy. To relieve hot flushes, you should limit or avoid hot drinks and cigarettes.

Breast TendernessBreast tenderness or sensitive and painful breasts usually occurs because of high dose of Casodex. Tamoxifen alleviates breast tenderness. Alternatively, before starting hormonal therapy you might have radiotherapy in a small dose.

Tumour Flare Pain

This pain can become worse after hormonal therapy starts. Bisophosphonates are used for treating tumour flare pain.
