ADH and Estrogen Only HRT

Posted by adh0824 @adh0824, Sep 18, 2023

I was recently diagnosed with ADH, a wide excision biopsy was recommended and am waiting for my first appointment with a doctor at Mayo Breast Clinic on Oct 2. I have been on estrogen-only HRT for 14 years (complete hysterectomy in 2009). I am 70. There seems to be some research that estrogen-only therapy HRT ( .5 mg daily) may reduce breast cancer incidence and so my family doctor has suggested I stay on it at least until I see the doctor at Mayo on Oct 2.
Does anyone have any experience or knowledge about estrogen-only HRT and ADH?

I had an excision for ADH 8 years ago which meant I could not follow through with planned HRT. I am so glad my OB/Gyn made that decision. This year I was diagnosed with a breast cancer that was 100% estrogen receptor positive in the same location.

Can I ask your BC stage and treatment plan? How long ago did you stop 6 month monitoring protocol?

I think I did diagnostic mammograms at 6 months a few times, then a diagnostic a year later, and finally moved to regular mammograms at 2-3 years out from ADH finding. Today's protocols would include a baseline MRI but I was not given one. My recent dx was for an uncommon type of breasr cancer (2-4%), stage 1c. Thankfully I am not the norm as 85% of people with ADH do not have breast cancer in their future.

You'll find a lot of up to date information on HRT after breast cancer in Dr. Avrum Bluming's book, ESTROGEN MATTERS.

Dr. Bluming has been studying the topic for decades.

Avrum Bluming, M.D., received his BA from Columbia College, where he majored in music, and his M.D. degree from the Columbia College of Physicians and Surgeons. He spent four years as a Senior Investigator for the National Cancer Institute and has taught at medical and academic institutions, including Harvard, Princeton, Johns Hopkins and Columbia Universities, as well as UCLA and USC. He is currently an Emeritus Clinical Professor of Medicine at USC, and has been an invited speaker at the Royal College of Physicians in London, the Pasteur Institute in Paris, and the International Society of Hematology in Jerusalem. In 1994, he was elected to Mastership in the American College of Physicians, an honor accorded to only 500 of the over 100,000 board-certified internists in the U.S. Since 1994, he has been consistently listed in The Best Doctors in America. For more than three decades, Dr. Bluming has been studying the benefits and risks of hormone replacement therapy administered to women with a history of breast cancer. His book with Dr. Carol Tavris, Estrogen Matters: Why taking hormones in menopause can improve women’s well-being and lengthen their lives—without raising the risk of breast cancer (Little, Brown Spark, 2018), has, along with controversy, been received with praise and support from researchers, physicians, and hundreds of grateful women around the world. The Second edition is due to be released September 3, 2024.

Here is a quote from an interview with Dr. Bluming,

"There are now 26 studies in the medical literature that I could find in languages that I can understand, and I reviewed all of those studies. Of the 26 studies, 25 show no increased risk of recurrence of breast cancer among women who take hormone replacement therapy of any kind. And that’s independent of whether they had estrogen receptor positive or estrogen receptor negative breast cancer. The one study that suggested an increased risk of recurrence is a study that was done in Sweden called the HABITS Study. HABITS stands for Hormones After Breast Cancer: Is it Safe? And that study reported an increased risk of contra, or local breast cancer, not an increased risk of distant recurrence. And there was no increased risk of death from breast cancer. And the study has several problems, including that it did not mandate baseline mammograms for women going into the study, which you would need in order to know to know that a local recurrence wasn’t there before starting."
