Hormone Therapy Possibilities for Breast Cancer Survivors and Women at High Risk for Cancer
by Pete Hueseman R.Ph.,P.D., Consultant Pharmacist

Read Pete Hueseman's last transcript 

Past History of Breast Cancer

Patients with past history of breast cancer should not have estradiol or estrone recommended for estrogen supplementation. These estrogens play a role in causing breast cancer by damaging DNA. Estriol is the protective estrogen that is high during pregnancy. It does not activate the estrogen receptor, but occupies the receptor sites so that it is not available for estradiol. Hormone balance is important, and testing of hormone levels is recommended prior to supplementing. For post breast cancer patients, many medical practitioners do not recommend hormone supplementation, except for progesterone, unless hormone levels are well below normal and symptoms are severe. Use of hormones should be carefully tracked by both patient and doctor.

Here's what we suggest:
  • Estriol should be recommended (2 mg twice a day) and is thought to reduce the risk of breast cancer recurrence. For atrophy of vaginal tissues and urethral problems in post breast cancer patients, a compounded estriol cream (.5 mg/gram applied topically 2 - 3 times a week) is considered safe.
  • Progesterone has the effect of down regulation of estrogen receptors in breast and uterine tissue.
  • Testosterone has been reported in some studies to have an anti-carcinogenic effect on breast cancer cells and in clinical studies has demonstrated increased survival rates for patients receiving testosterone vs. those who did not.
  • Arimidex prevents aromatization of testosterone to estradiol and aromatization of androstenedione to estrone. The ATAC study has documented Arimidex as better than tamoxifen or placebo for early-stage, hormone-receptor-positive breast cancer. The early ATAC results do suggest that Arimidex might have benefits over tamoxifen, but the decision to start taking Arimidex instead of tamoxifen is not clear-cut at this point.

    Two things we know about Arimidex:

    1. Arimidex and tamoxifen should not be taken together. There appears to be no proven advantage to the combination over tamoxifen or Arimidex alone, and you may have side effects from both drugs.
    2. Aromatase inhibitors have no proven role in pre-menopausal women diagnosed with breast cancer.
  • Indole-3-Carbinol prevents conversion of 2-hydroxyestrone to the carcinogenic 16-hydroxyestrone and 4-hydroxyestrone.
Drug therapy recommendations:
  1. Estriol 2.5 mg + Progesterone 100 mg + Testosterone 1.25 mg. Take one sublingual tablet twice a day.
  2. Arimidex (anastazole) 1 mg tablets. Take one everyday.
  3. Indole-3-carbinol 400 mg. Take one capsule daily.

Certainly a person with an estrogen-receptor-positive tumor is at much higher risk with estradiol treatment than an estrogen-receptor-negative tumor. However, both types of tumors have an elevated risk of recurrence with estradiol treatment.

My thoughts are that a patient with a history of estrogen-receptor-positive tumor should DEFINITELY be on Arimidex for life! She also should not receive estradiol, of course. The other hormones (except DHEA) are fine. The downside for women at risk of breast cancer is that DHEA can convert to estrogen and has a stimulatory effect on breast cells, particularly when estrogen is low. Close watch on overall hormone balance levels is required, and testing is recommended every 6 months. In terms of estrogen receptor negative, I would say that Arimidex is probably not a must.

High Risk for Breast Cancer

A patient with a high risk (based on the Gail Model) for breast cancer would benefit from supplementation of estrogen and progesterone with human identical hormones in ratios similar to those in the human body.

Progesterone is recommended for benefits of fluid balance and protection against cancer. Progesterone has the effect of down regulation of estrogen receptors in the breast.

Patients are also likely to benefit from estriol with its potential for protection against breast cancer recurrence due to its low estrogenic activity, which possibly results in binding to estrogen receptors without stimulation of receptor. This is recommended in a higher ratio of estriol to estradiol than the typical ratio seen in Biest (80%/20%). For patients with a higher risk for breast cancer, we recommend 90%/10% estriol/estradiol.

We also recommend Indole-3-Carbinol to prevent conversion of 2-hydroxyestrone to the carcinogenic 16-hydroxyestrone and 4-hydroxyestrone. This will provide additional protection against breast cancer and should be considered in the patient with positive family history.

Drug Therapy Recommendations:
  1. 90% estriol/10% estradiol sublingual tablet. Take one under the tongue twice a day.
  2. Progesterone 100 mg sublingual tablets. Take one under the tongue twice a day.
  3. Indole-3 Carbinol (Cervaplexx I3-C) 400 mg. Take one every day.

In response to the book "The Sexy Years" by Suzanne Somers, we have not found in the last 12 years any significant increase in insulin resistance with continuous therapy. I do not feel it is necessary to cycle therapy if you have been in post-menopause for over one year.

Lastly, in most instances it will be rather difficult for patients to find an endocrinologist in their area to work with them and natural hormone therapy. My suggestion for women would be to use your regular OB-GYN and contact us if the patient needs assistance.
