Hormone therapy is a non-curative form of therapy. The end result is a decrease in testosterone level. This stops the cancer from progressing for a temporary time. Hormone therapy is often used in combination with IMRT or seed brachytherapy in high risk patients. It can also be used to reduce the size of the prostate gland prior to seed implant in a low risk patient.
This type of therapy can be administered orally or via injection. Short-term side effects can include hot flashes, mood swings, fatigue and loss of sex drive. Long-term side effects can include weight gain, diabetes, osteoporosis, high cholesterol, breast tenderness and/or enlargement and possible cardiac complications.
