Understanding the Role of Estrogen in Breast Cancer Risk and Prevention


  • Breast cancer is a common cancer in women, with the highest risks for women between the ages of 25 and 65.
  • The focus in oncology is often on treatment after the disease has occurred, rather than on prevention and risk reduction.
  • The author has found that breast cancer occurrence could be significantly reduced if women knew how to prevent it.

Diagnosis and Assessment

  • There are several diagnostic tools used to assess relative breast cancer risks, including genetic testing, breast imaging screenings, and assessment of environmental toxin exposure, hormonal use, and various personal factors.
  • Early detection through screenings is important, but it is also important to consider the risks of radiation exposure through frequent mammography.

Estrogen and Breast Cancer

  • Most breast cancers in the US are estrogen-receptor positive, meaning they are fueled by excess estrogen.
  • Estrogen is important for various aspects of women's health, including reproductive and sexual maturation, brain and heart health, and bone health.
  • However, excessive estrogen levels can increase the risk of cancer, as well as other conditions such as insulin resistance, diabetes, and obesity.

Sources of Estrogen

  • The body has over 100 different estrogen molecules, with the most common being estrone, estradiol, and estriol.
  • Estrogen is produced by the ovaries, uterus, and adrenal glands.
  • Estrogen dominance, or excessively high estrogen levels, can be caused by various factors including hormonal imbalances, environmental toxins, and certain medications.

Preventing Estrogen Dominance and Reducing Breast Cancer Risks

  • There are several steps that can be taken to prevent estrogen dominance and reduce the risk of breast cancer, including:
  • Balancing hormones through diet, supplements, and lifestyle changes.
  • Reducing exposure to environmental toxins.
  • Supporting liver function to improve estrogen metabolism.
  • Incorporating natural estrogens and hormone balancing herbs into the diet.
  • Using natural progesterone to balance estrogen levels.
  • Reducing stress and maintaining a healthy weight.

Consult with a TCM Practitioner

If you are experiencing symptoms or health concerns that you believe may be related to Traditional Chinese Medicine (TCM) patterns, it is important to consult with a qualified TCM practitioner. A TCM practitioner will be able to assess your specific situation and provide you with a personalized treatment plan based on your unique needs and constitution. During your consultation, the practitioner will ask you about your health history, symptoms, and lifestyle habits, and may also assess your pulse, tongue, and other physical signs to determine the underlying causes of your condition. Working with a TCM practitioner can be an effective way to address a wide range of health issues and promote overall balance and well-being.
