How much does HRT increase breast cancer risk?

Written by Ethan Davis - January 22, 2023

Introduction

Hormone replacement therapy (HRT) is a common treatment for menopausal symptoms, including hot flashes, night sweats, and vaginal dryness. However, there has been concern about the potential increased risk of breast cancer associated with HRT use. In this post, we will explore the evidence regarding HRT and breast cancer risk.

What is Hormone Replacement Therapy?

Hormone replacement therapy involves taking hormones to replace those that the body no longer produces naturally after menopause. The most commonly used hormones in HRT are estrogen and progesterone. Estrogen-only therapy is generally recommended for women who have had a hysterectomy, while combination therapy (estrogen plus progesterone) is recommended for women who still have their uterus.

Breast Cancer Risk Factors

Before discussing the link between HRT and breast cancer risk, it's important to understand what factors increase a woman's risk of developing breast cancer. Some key factors include:

  • Age: The risk of breast cancer increases as women get older.
  • Family history: Women with a family history of breast cancer are at higher risk.
  • Genetic mutations: Certain genetic mutations (such as BRCA1 and BRCA2) increase the risk of breast cancer.
  • Personal history: Women who have had breast cancer or certain non-cancerous breast conditions are at higher risk.
  • Lifestyle factors: Alcohol consumption, obesity, and lack of physical activity can all increase the risk of breast cancer.

Evidence Regarding HRT and Breast Cancer Risk

Several large studies have looked at the link between HRT use and breast cancer risk. These studies have found that:

  • Combination HRT use (estrogen plus progesterone) increases the risk of developing breast cancer.
  • Estrogen-only therapy may also increase the risk of breast cancer, but to a lesser extent than combination therapy.
  • The increased risk appears to be highest during the first few years of HRT use.
  • The increased risk decreases after stopping HRT use.

It's worth noting that while these studies suggest an increased risk associated with HRT use, they do not prove causation. Other factors, such as lifestyle habits or pre-existing medical conditions may contribute to an elevated risk.

Reducing Breast Cancer Risk While Using HRT

If you're considering using hormone replacement therapy but concerned about your breast cancer risk, there are steps you can take to reduce your overall risk:

  • Talk to your doctor about your individual risks before starting any treatment.
  • Consider alternative treatments for menopausal symptoms if appropriate.
  • If you do decide to use HRT, choose estrogen-only therapy if possible.
  • Limit alcohol consumption and maintain a healthy weight through diet and exercise.
  • Get regular mammograms as recommended by your doctor.

Alternative Treatments for Menopausal Symptoms

While hormone replacement therapy is often effective in treating menopausal symptoms, it's not right for everyone. There are several alternative treatments available that may help relieve symptoms without increasing your breast cancer risk:

  • Non-hormonal medications such as antidepressants or gabapentin
  • Herbal supplements like black cohosh or red clover
  • Lifestyle changes such as regular exercise or stress reduction techniques
