The Minority Benefit: Why Hormone Blockers Help Some Women but Fail Many

For as long as I have worked in women’s health, I have heard the same script. Estrogen “feeds” breast cancer. The safest thing we can do is block it, hard and for as long as possible. Aromatase inhibitors, tamoxifen, and the other endocrine drugs are framed as our best hope.

A woman finishes five years of endocrine therapy. She did everything that her oncology team told her to do. She took the pill every day. She lived with the hot flashes, the aching joints, the foggy brain, the sleepless nights. She was told this treatment would lower her chance of the cancer returning.

And then, years later, it comes back anyway.

I hear this story more often than most women are ever told to expect. And when it happens, the question we ask is almost always the wrong one. We ask…..

Why the “Estrogen Villain” Story Never Made Sense to Me

For as long as I have worked in women’s health, I have heard the same script. Estrogen “feeds” breast cancer. The safest thing we can do is block it, hard and for as long as possible. Aromatase inhibitors, tamoxifen, and the other endocrine drugs are framed as our best hope.

On paper, it sounds neat and logical. In real women’s lives, it has never fully added up for me.

I keep coming back to one stubborn fact. When you step back and look at absolute risk reduction, not just the relative percentages, the benefit of years of estrogen blockade is far more modest than the message implies. Many women do everything right, stay on these drugs for years, and still recur. I hear those stories every week.

What If Estrogen Isn’t the Enemy in BRCA?

Most women with a BRCA gene variation have been told some version of the same story: your hormones are dangerous, your ovaries are a ticking time bomb, and the safest path is to take them out early and stay away from estrogen for the rest of your life.

I understand why that story exists. The fear is real. The cancer risk is real. The decisions women have to make in their 30s and 40s are difficult.

But the more I read the actual science, the harder it is to hold that story without asking some more questions. Because the same estrogen women are told to fear may also be one of the things their cells use to fix themselves, and to keep their energy systems running.

Debunking the Continuous Progesterone Myth: Unopposed Estradiol Is the Real Concern

Lately, our inboxes have been flooded.

Women are reading things on social media that are frightening them, confusing them, and in some cases making them want to stop their progesterone.

So instead of trying to answer one DM at a time, I decided to bring two of the people I trust most in this space — Carol Petersen, RPh and Phyllis Bronson, PhD — to the table to talk it through together.

Why the Testosterone Blood Test Is Not Telling You What You Think It Is

If you have ever had your testosterone checked and been told the number was “normal,” or “too high,” or “out of range,” there is something important you were probably not told.

The blood test is not measuring what most women think it is measuring.

It is measuring one slice of testosterone. A small one. And the lab range printed next to that number was built for a different purpose than guiding hormone treatment. Once you understand what the test actually shows, the whole conversation about dosing, safety, and “normal” levels changes.

The Neighborhood Inside Your Tumor: How Your Daily Life Affects Cancer Biology

If you have been told that endocrine therapy, such as tamoxifen or an aromatase inhibitor, is the only answer after breast cancer, you are not alone. Many women leave oncology visits with a treatment plan, a prescription, and very little discussion about anything else.

What you eat, how you move, how you sleep, your metabolic health, your stress levels, your muscle mass, your inflammation, your alcohol intake, your insulin levels, your relationships, and your overall internal environment are often barely mentioned, if they are mentioned at all. Lifestyle is rarely presented as part of cancer biology in a meaningful way. It is even more rarely discussed as part of recurrence prevention.

That's what I want to talk about. The neighborhood. The terrain.

Duavee Mania: Is It Really Better Than What Is Already in Front of Us?

If you have spent any time in the menopause corner of the internet, you have probably heard it by now. Several well-known voices on social media and popular podcasts are promoting the use of Duavee for women to prevent breast cancer, for women with DCIS, or for women who simply want to stay "safe." And just like that, a quiet little pill becomes the next thing every woman is told she should be on to prevent breast cancer.

Breast Cancer Doesn't Grow in a Healthy Neighborhood (Part 2)

Today I want to zoom out even further.

Because here's the truth I keep coming back to in my work. Cancer cells don't just go rogue. They don't drop out of the sky. A cancer cell is a cell that finally couldn't keep up. It couldn't repair itself, couldn't make enough energy, couldn't keep its signaling clean. And it lived in a body that, for many reasons, had stopped being a healthy place to live.

That's what I want to talk about. The neighborhood. The terrain.

Breast Cancer Doesn't Just Grow Through Estrogen: The Other Pathways No One Tells Women About (Part 1)

Every week, I hear from women who have been told some version of the same sentence:

"Your cancer was ER-positive, so estrogen caused it."

"You can never go near estrogen again."

"Stay on this anti-estrogen drug for the next five, ten, or fifteen years, or your cancer will come back."

I understand the fear behind those statements. I really do. But the more I read the science, the more I see that this story is incomplete. And women deserve the full story.

Why Not All Progestins Are Created Equal — And Why I Am Cautious About the Pill and the Hormonal IUD

If you have been told that "the pill is safe," or that the hormonal IUD is just a tiny, local dose, you are not alone. Most women hear some version of this. And for some women, the pill or the IUD really may be the right tool. But there is a longer conversation that does not always make it into the visit.

Dialing Down the Noise: How to Simplify Your Menopause Plan and Build a Health & Vitality Toolbox That Works

Every week, I talk to women who feel totally overwhelmed by all the noise about menopause, midlife, and longevity. There are soooooooo many opinions out there.

Confused about which type of estrogen replacement therapy is best? You are not alone. It's a hot topic in the world of menopause medicine.

If you were to survey menopause practitioners from around the globe and ask them their preferred type of estrogen replacement therapy, you'd get many different answers.  That’s because practitioners who prescribe hormone replacement therapy (HRT) come from various training backgrounds and have vastly different experiences treating patients with HRT.

The Truth About Estrogen, Breast Cancer, and Hormone Therapy: What the Latest Research Reveals

No one knows for sure what causes breast cancer to develop, although cancer stem cells (a kind of cell that has nothing to do with estrogen) are thought to play a role. Cancer causes are complex and related to many issues including inflammation, stress, exposure to radiation, viruses, chemicals, and other factors.
