Hormone Therapy and Cancer

“Cancer risk from HRT is small and depends on
many different things. This includes the type of HRT used,
how long someone takes it for, their age, and…”.1

Umbrella
What may the Hormone Therapy and Cancer Umbrella include?

Depending on the Source (DotS) this Umbrella may include:

  • Bowel/Colon/Rectum Cancer
  • Breast Cancer
  • Cancer
  • Cervical Cancer/Cancer of the Cervix
  • Hormone Replacement Therapy (HRT)
  • Hormone Therapy (HT)
  • Lung Cancer
  • Menopausal Hormone Therapy (MHT)
  • Ovarian Cancer/Cancer of the Ovary
  • Uterine/Womb/Endometrial Cancer

Terminology

What can it be important to be clear about with hormone therapy (HT),  hormone replacement therapy (HRT) or menopausal hormone therapy (MHT) and cancer information?

It can be important to be clear about the type of HT such as estrogen therapy (ET) or estrogen plus progestogen therapy (EPT).

What can it also be important to be clear about with HT, HRT or MHT and cancer information?

It can also be important to be clear about the type of cancer (e.g. breast, ovarian or uterus/womb cancer).

Risk

What is cancer risk from HT?

In Does Hormone Replacement Therapy Increase Cancer Risk? Should I Take HRT? the (United Kingdom) Cancer Research UK elaborate on:

“Cancer risk from HRT is small and depends on many different things. This includes the type of HRT used, how long someone takes it for, their age, and general health. The benefits of taking HRT will be different for each person too. Cancer risk is only part of the decision on whether to take HRT. Your doctor can help you make an informed choice on what is right for you”.2

Who is a GP?

Dots and/or DotC (Depending on the Country) a GP may be a registered general practitioner, a medical practitioner, a medical doctor or a doctor.

Cancer Risk Reduction

How can the risk of cancer be reduced?

In Does Hormone Replacement Therapy Increase Cancer Risk? Should I Take HRT? Cancer Research UK also note:

“Eating a healthy, balanced diet and being active may help with menopause symptoms. This can also help reduce your risk of cancer. Other things you can do to reduce your risk of cancer include:

  • Stopping smoking
  • Keeping a healthy weight
  • Drinking less alcohol”.3

Risks and Benefits

Is HT effective for the treatment of menopausal symptoms?

In Risks and Benefits of MHT: Key Points the Australasian Menopause Society elaborate on:

  • “For the majority of symptomatic women, the benefits of menopausal hormone therapy (MHT) outweigh the risks”.4

Breast Cancer RiskHormone Therapy and Cancer RiskHormone Therapy and Cancer Risk

Can taking HT increase breast cancer risk?

On page one in Deciding About Hormone Therapy Use: Potential Risks, published July 2022, the North American Menopause Society (NAMS) note:

“Hormone therapy (combined estrogen and progestogen) might slightly increase your risk of breast cancer if used for more than 4 to 5 years. Using estrogen alone (for women without a uterus) does not increase breast cancer risk at 7 years but may increase risk if used for a longer time”.5

On page two and three in the Joint Position Statement By the British Menopause Society, Royal College of Obstetricians and Gynaecologists and Society for Endocrinology on Best Practice Recommendations for the Care of Women Experiencing the Menopause, first published online 10 June 2022, one of the recommendations is:

“Current evidence suggests that oestrogen alone HRT is associated with a lower risk of breast cancer than combined HRT. Breast cancer risk is duration dependent and may vary with the type of progestogen used. The risk of breast cancer should be considered in the context of the overall benefits and risks associated with HRT intake”.6

Ovarian Cancer Risk

Can taking HT increase ovarian cancer risk?

On page two in HRT Benefits and Risks, published November 2020, the (British) Women’s Health Concern note:

“Recent evidence from the Collaborative Group on Hormonal Factors demonstrated that there may be a slight increased risk of some types of ovarian cancer associated with HRT use but this is small and equates to around 1 extra case of ovarian cancer per 1000 HRT users”.7

Cancer of the Uterus

Can taking HT increase cancer of the uterus risk?

On page one in Deciding About Hormone Therapy Use: Potential Risks, published July 2022, the NAM explain:

“If you have a uterus and take estrogen with progestogen, there is no increased risk of cancer of the uterus”.8

History of Cancer

Can HT be taken by those with a history of cancer?

In Menopause FAQs: Hormone Therapy for Menopause Symptoms – Q. Who should not use hormone therapy? the NAMS note:

“A. Hormone therapy is not a good choice for every woman. For some, the risks outweigh the benefits, so careful consideration with a healthcare provider is advised. In general, women who have breast cancer, uterine cancer, unexplained uterine bleeding, liver disease, a history of blood clots, and cardiovascular disease should not use hormone therapy”.9

History of Breast Cancer

Can HT be taken by those with a history of breast cancer?

In Making Decisions About Hormone Replacement Therapy, last dated on 30 June 2022, Breastcancer.org elaborate on:

“Research on menopausal hormone therapy will continue, as will the ongoing debate about benefits versus risks. At this point, HRT — whether in the form of combination HRT or estrogen-only HRT — is not recommended for women who have been diagnosed with breast cancer”.10

On page three in the Joint Position Statement By the British Menopause Society, Royal College of Obstetricians and Gynaecologists and Society for Endocrinology on Best Practice Recommendations for the Care of Women Experiencing the Menopause, first published online 10 June 2022, one of the recommendations is:

“A history of breast cancer should be considered a contraindication to systemic HRT. The risk of breast cancer recurrence with HRT is higher in women with oestrogen receptor positive cancer, but women with oestrogen receptor negative breast cancer are also considered to have an increased risk of recurrence with HRT. HRT may, in exceptional cases, be offered to women with breast cancer with severe menopausal symptoms if lifestyle modifications and non-hormonal treatment options are not effective. This should be done after discussion with the woman, her menopause specialist and her breast/oncology team”.11

Health Care Provider

If I choose to use HT what are my risks of cancer?

On page one in Deciding About Hormone Therapy Use the NAMS explain:


Hormone Therapy and Cancer
“Every woman is different, and you will decide about whether to use HT based on the severity of your symptoms, your personal and family health history, and your own beliefs about menopause treatments. Your healthcare professional will be able to help you with your decision”.12
