“For healthy women with bothersome hot flashes aged
younger than 60 years or within 10 years of menopause,
the benefits of HT generally outweigh the risks”.1

Umbrella

What may the Hormone Therapy Risks Umbrella include?

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

  • Hormone Replacement Therapy (HRT) Risks
  • Hormone Therapy (HT) Risks
  • Menopausal Hormone Therapy (MHT) Risks

Date

What can it be important to be clear about with hormone therapy (HT) risks information?

It can be important to be clear about the date of all information including the date of HT risks information, because this information may have been updated.

Symptoms or Chronic Conditions

What can it also be important to be clear about with HT risks information?

It can also be important to be clear about whether HT risks information is about the use of HT for the management of menopausal symptoms such as hot flushes, night sweats and vaginal dryness or for the prevention of chronic conditions such as cardiovascular disease, cancer, dementia and osteoporosis.

One Size Fits All

Are different types of HT available?

No. In HRT – Types, Doses and Regimes the (British) Women’s Health Concern elaborate on:

“Many types of HRT are available and there is not one type, dose or regimen which suits all women. It is important to understand which hormones are used, why and how so that for each woman who chooses to take HRT, the treatment is individualised to best suit her needs, taking into account types of symptoms, medical history, period pattern if present and current national recommendations and guidelines”.2

Risks

What are some risks associated with HT?

In Menopause Management Options: Menopausal Hormone Therapy (MHT) – What Are the Risks of MHT?, last updated 08 May 2024, the (Australian) Jean Hailes for Women’s Health (JH) elaborate on:

“Research shows there are some risks associated with MHT. The risks of hormone therapy differ depending on:

  • The type of medication
  • The dose given
  • How long the medication is used for
  • How the medication is given (e.g. patch or tablet)
  • When medication is started
  • Whether a progestogen is used
  • The type of progestogen used”.3

Risks vs Benefits

Are the risks of HT generally outweighed by the benefits?

In Risks and Benefits of MHT: Supporting Women Making A Decision the Australasian Menopause Society elaborate on:

  • “The risks of MHT must be considered in perspective for each woman and balanced against the benefits, particularly the severity of symptoms
  • Management of menopausal symptoms should be tailored to the individual woman to effectively manage her symptoms and minimise risks
  • For some women any extra risk will be unacceptable but others may feel that the benefits outweigh the risks”.4

NICE Guidelines

What did the (British) National Institute for Health and Care Excellence’s (NICE) guidelines note about the benefits and risks of hormone replacement therapy (HRT)?

In Menopause: Diagnosis and Management – Information for the Public: Benefits and Risks of HRT, last Updated: 05 December 2019, the NICE explain and elaborate on:

“NICE looked at the risks of the following conditions in women taking HRT compared with women of menopausal age in the general population. Your GP should explain that the risks of the conditions described below vary from one woman to another and depend on many risk factors. In cases where HRT is said to increase risk this usually means a very small increase in most women.

  • Blood Clots (Venous Thromboembolism)…
  • Heart Disease and Stroke (Cardiovascular Disease)…
  • Breast Cancer…
  • Type 2 Diabetes…
  • Osteoporosis…
  • Loss of Muscle Strength…
  • Dementia…”.5

Who is a GP?

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

Younger Than 60 Years

Younger than 60 years, do the benefits of HT generally outweigh the risks?

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

“As with all medications, HT is associated with some potential risks. For healthy women with bothersome hot flashes aged younger than 60 years or within 10 years of menopause, the benefits of HT generally outweigh the risks”.6

In Menopause Management Options: Menopausal Hormone Therapy (MHT) – What Are the Risks of MHT? the JH elaborate on:

“A recent comprehensive review of evidence on MHT found it is an effective and safe treatment for the relief of menopausal symptoms for healthy women. The data showed that MHT had low risks for women aged between 50 and 60 years, but more research is needed to understand how MHT might affect other women’s health issues”.7

Older Than 60 Years

Older than 60 years or postmenopausal for 10 years or more, is it recommended women do not start HT?

The JH note:

Hormone Therapy Risks“It is not recommended you start MHT if you are older than 60 years or if you’ve been postmenopausal for 10 years or more”.8

After Age 65

In women older than 65 years, can starting HT increase the risk of dementia?

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

“If started in women aged older than 65 years, HT might increase the risk of dementia”.9

Breast Cancer Risk

Can HT increase breast cancer risk?

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

“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”.10

On page two 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 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”.11

Other Conditions

Can HT increase the risk of other conditions?

In Hormone Replacement Therapy (HRT): Benefits and Risks of Hormone Replacement Therapy (HRT) – Research Into HRT and Other Conditions, page last reviewed 08 February 2023, the NHS note:

“Research has shown that taking HRT has little or no effect on the risk of getting coronary heart disease.

More research is being done to find out how taking HRT affects some other conditions, such as dementia and diabetes. Any increased risk or benefit is likely to be small.

It’s not known whether HRT reduces the risk of dementia.

HRT does not increase the risk of developing type 2 diabetes. Some recent studies have suggested that it may even slightly reduce the risk”.12

Not Advised

When may using HT not be advised?

The JH note:

“Your doctor may advise you not to use MHT if it could increase your health risks. For example, if you have:

  • Cancer (e.g. breast or uterine)
  • Undiagnosed vaginal bleeding
  • Heart disease”.13

Health Care Provider

What if I choose to use HT, how can I find out what my risks and benefits are?

If you choose to use HT, it may be in your best interest to also choose to talk to your health care provider about this.

In BMS & WHC’s 2020 Recommendations on Hormone Replacement Therapy In Menopausal Women the British Menopause Society (BMS) and Women’s Health Concern (WHC) note:


Hormone Therapy Benefits and Risks“The decision whether to take HRT, the dose of HRT used and the duration of its use should be made on an individualised basis after discussing the benefits and risks with each patient. This should be considered in the context of the overall benefits obtained from using HRT including symptom control and improving quality of life as well as considering the bone and cardiovascular benefits associated with HRT use”.14

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

“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”.15

In Menopause: Diagnosis & Treatment – Treatment: Hormone Therapy the (United States) Mayo Clinic note:

“Before deciding on any form of treatment, talk with your doctor about your options and the risks and benefits involved with each. Review your options yearly, as your needs and treatment options may change”.16
