We believe that…

A doctor and her patient are equal partners in health. As our patient, you should fully understand and consent to all recommended treatments.
The best treatment is the most natural, least toxic treatment. Many pharmaceuticals have terrible side effects. These powerful drugs should be last resorts, not first-line treatments.
Illnesses are usually interconnected. We want you to tell us about all of your symptoms so we can treat them together.
In many cases, the body can heal itself. Your body is designed to be healthy. If you give your body what it needs, it can usually heal all on its own.
The goal of medicine is optimal health, not tolerable illness. We want you to feel amazing.
Health is an ongoing journey. As you travel through life, we will be here for you.

Dr. Felice Gersh Interview

Dr. Gersh is the medical director of IMGI and is board-certified in Integrative Medicine and OB-GYN. She is a globally-renowned expert in women’s health and complex disease management.

Why do women live longer than men? Does the ability to bear children play a role and to what extent do evolutionary forces discriminate between men and women?

In this in-depth interview Dr. Gersh explains why she “had to unlearn” about half of everything she learned at medical school calls for a fundamental “shake-up” in the delivery of health care.

After menopause, if a woman is NOT on hormone replacement therapy AND she has dense breasts, then that is a sign of inflammation and that IS a risk factor for breast cancer.

So, in summary:
🚫 Dense breasts in a reproductive-aged woman with natural levels of ovarian estradiol = NOT a risk
🚫 Dense breasts in a menopausal woman taking human-identical hormone replacement therapy = NOT a risk
Dense breasts in a menopausal woman not on hormone replacement therapy = YES, a risk for breast cancer

You can watch my full talk about breast density and cancer risk on youtube.

After menopause, if a woman does take estrogen as part of hormone replacement therapy, the estrogen will stimulate the ductal cells the same way that estrogen does in a reproductive-aged woman. This is keeping the breasts young, healthy, and, yes, dense. So women on HRT will have dense breasts and this is NOT an increased cancer risk.

After menopause, if a woman is NOT on hormone replacement therapy, a normal mammogram will look dark because the breasts lose their density and become mostly fat. The ductal cells, which are important for breast feeding and which create breast density, atrophy and shrivel up without estrogen. So, dense breasts after menopause in a women not taking hormones are not normal. Watch my entire talk to learn why.

In reproductive-aged women, dense breasts are NORMAL. They are not a cancer risk.

A study recently came out showing that women don't understand the risks associated with dense breasts. This is the least surprising thing ever since most doctors don't either. In this video, I talk about which women have dense breasts (hint: most young women do!) and why breast density is associated with an increased cancer risk primarily in a very specific group of women.

I'm so proud to announce that an article that I authored with colleagues Dr. Jim Parker and Claire O’Brien for the Australian and New Zealand Journal of Obstetrics and Gynaecology is one of the top cited articles of the past year.

Understanding the origins of PCOS and the interplay of genetics, the in-utero environment, lifestyle, and environmental factors is key to both treating PCOS and empowering women to minimize the inheritance of PCOS by their daughters.

From the Abstract:
Human observational and animal experimental data support the hypothesis that PCOS is an inherited condition that arises as a result of developmental programming of normal gene variants. It is likely that these genes can be amplified by in-utero androgen exposure and activated by a range of postnatal lifestyle and environmental factors. Endocrine disrupting chemicals have the potential to influence developmental programming of PCOS susceptibility genes.
