What are the side effects of hormone therapy?

The following are some potential side effects that may occur with hormone therapy. However, the side effects will vary depending upon the type of hormone therapy that is given. Every person’s hormone treatment experience is different and not every person will experience the same side effects. Discuss the potential side effects of your hormone therapy with you physician.

As each person's individual medical profile and diagnosis is different, so is his/her reaction to treatment. Side effects may be severe, mild, or absent. Be sure to discuss with your cancer care team any/all possible side effects of treatment before the treatment begins.

For prostate cancer, either the surgical removal of the testes or hormone drug therapy can improve the cancer. Both surgery and drugs may cause the following side effects:

  • hot flashes
  • impotence
  • a loss of desire for sexual relations
  • male breast enlargement

For breast cancer, some women may experience side effects from tamoxifen that are similar to the symptoms some women experience in menopause. Other women do not experience any side effects when taking tamoxifen. The following are some of the side effects that may occur when taking tamoxifen:

  • hot flashes
  • nausea and/or vomiting
  • vaginal spotting (a blood stained discharge from the vagina that is not part of the regular menstrual cycle)
  • increased fertility in younger women
  • irregular menstrual periods
  • fatigue
  • skin rash
  • loss of appetite or weight gain
  • headaches
  • vaginal dryness or itching and/or irritation of the skin around the vagina

Taking tamoxifen also increases the risk of endometrial cancer (involves the lining of the uterus) and uterine sarcoma (involves the muscular wall of the uterus), both cancers of the uterus. There is also a very small risk of blood clots and stroke, eye problems such as cataracts, and liver toxicities. Tamoxifen should be avoided during pregnancy.

Tamoxifen is used to treat men with breast cancer as well. As each person's individual medical profile and diagnosis is different, so is his/her reaction to treatment. Side effects may be severe, mild, or absent. Be sure to discuss with your cancer care team any/all possible side effects of treatment before the treatment begins.

Men may experience the following side effects:

  • headaches
  • nausea and/or vomiting
  • skin rash
  • impotence
  • decrease in sexual interest
