HRT after cancer

If you have a history of cancer and are thinking about taking hormone replacement therapy (HRT), you should know the risks.

  • Women with a history of breast cancer may be advised not to take HRT. This is because there are concerns that the estrogen in HRT may cause breast cancer to come back. Different studies tell us different things about the effects of HRT on women with breast cancer, so the risk is not yet fully understood.
  • HRT may be an option for women at a higher risk for breast cancer. Although women with an increased risk for breast cancer are usually advised not to take HRT, it might be advised if they have proper counselling and follow-up.
  • Women with a history of uterine cancer may be advised not to take HRT. Women who have had higher stage and higher grade uterine tumours have a higher risk of the cancer coming back.
