Hi Friends,
Happy October! It happens to be my birthday month, but it's also Breast Cancer Awareness Month. 🩷
Each year, more than 300,000 women in the U.S. are diagnosed with breast cancer. While genetics play a role, lifestyle factors can also influence our risk, including alcohol consumption, physical activity, and body weight.
One fascinating area of research is the connection between our gut microbiome and estrogen metabolism.
Did you know that your gut bacteria actually help regulate estrogen levels?
This special part of your gut microbiome is called the estrobolome.
Researchers are now exploring how imbalances in the estrobolome may influence the risk of estrogen-receptor positive (ER+) breast cancer, the most common type of breast cancer.
⚠️ The Hidden Hormone Highway
Your body clears estrogen in three important steps:
Phase 1 & 2 – Liver Detoxification:
Estrogen is first detoxified in the liver, using enzymes that depend on key nutrients such as magnesium, B vitamins, and sulfur compounds found in cruciferous vegetables.
Phase 3 – Gut:
Once the liver packages estrogens for excretion, some are released with bile into your intestines, where your estrobolome can influence whether they are eliminated or recycled.
So many people suffer from dysbiosis, an imbalance in their gut bacteria—like having "weeds" in their Gut Garden. Some of these "bad" bacteria produce an enzyme called beta-glucuronidase, which can recycle estrogen back into circulation!
🍷 The Truth About Alcohol and Breast Cancer
Let's address one of the most underappreciated risk factors: alcohol.
Alcohol can increase estrogen levels and affect the estrobolome, contributing to breast cancer risk.
Even one drink per day has been linked to a 7–10% increase in breast cancer risk, and the risk increases with greater alcohol consumption.
Consider minimizing or avoiding alcohol altogether, since there is no clear "safe" threshold for alcohol when it comes to cancer risk. Reducing alcohol is one important step you can take to protect your long-term health.
How can you celebrate without alcohol? There are so many delicious alcohol-free options available now! I recently discovered an alcohol-free prosecco that's actually quite good! 🥂
💡Dr. Rajsree's Key Tips for Preventing Breast Cancer
Optimize Key Nutrients
Magnesium at bedtime for estrogen detoxification, bowel regularity, and quality sleep.
Maintain Vitamin D levels between 60–90 ng/mL for cancer prevention.
Prioritize A Healthy Lifestyle
Focus on whole, unprocessed foods and cruciferous vegetables.
Practice mindful stress reduction and prioritize restorative sleep.
Reevaluate alcohol intake.
Exercise regularly.
Repair Your Gut Microbiome
A broad spectrum probiotic like our Probiotic 100 Billion can help restore a healthier estrobolome.
Herbal antimicrobials such as Berberine Pro and Oregano Oil correct dysbiosis and reduce estrogen-recycling bacteria. You can download my protocol for dysbiosis here.
Support Healthy Estrogen Metabolism
Estrogen Balancer (DIM + I3C)—compounds found in cruciferous vegetables like broccoli 🥦—help your liver convert harmful “dirty” estrogens into healthier “clean” forms.
Stop Estrogen Recycling
Calcium-D-Glucarate helps block the beta-glucuronidase enzyme in the gut, ensuring estrogens are properly excreted instead of being recycled.

Breast Cancer Screening: What You Need to Know
Early detection of breast cancer saves lives.
Mammography remains the standard of care for breast cancer screening.
However, mammograms have limitations, especially for women with dense breast tissue, which can obscure findings. In these cases, supplemental imaging is advised:
Breast Ultrasound: Provides additional detail for women with dense breasts or inconclusive mammogram results.
QT (Quantitative Transmission) Ultrasound: A new FDA-cleared, radiation-free 3D ultrasound that provides detailed images without compression or contrast agents. It’s currently approved as an adjunct to mammography—not a replacement—but shows promise in improving detection in dense breasts.
Breast MRI: Offers highly detailed imaging and is particularly useful in high-risk women. Most MRI protocols require gadolinium contrast, which may not be ideal for everyone. (Non-contrast MRI is typically used for checking the integrity of breast implants, rather than cancer screening.)
⚡ Help your Body Handle the Radiation
Although mammograms use low radiation levels, it’s a good idea to protect your body’s antioxidant defenses before and after screening.
My recommendations:
Antioxidant support: Take Glutathione (250 mg daily) and/ or Vitamin C (1000 mg daily) for one week before and after your mammogram.
Glutathione injection: A quick and effective way to boost detoxification capacity, available in our office for current patients.
Wear a thyroid shield: A simple, inexpensive collar that protects your thyroid from scatter radiation during your mammogram.
💗 Estrogen: The Power Hormone
—Not One to Be Feared
Estrogen is not the enemy. It’s the power hormone that protects your bones, brain, heart, skin, and metabolism, while enhancing mood, sleep, and sexual health.
The myth that hormone replacement therapy (HRT) causes breast cancer has left too many women suffering needlessly. In reality, it’s hormone imbalance—not well-balanced hormone therapy—that increases risk.
When prescribed and monitored carefully, bioidentical HRT (BHRT) can restore vitality and help women age vibrantly. Proper optimization of hormones can be one of the most powerful tools for enhancing longevity. Learn more in my video on Hormone Replacement Therapy in Menopause below.
Broccoli 🥦 is a cruciferous vegetable that has sulforaphane, which has anti-cancer properties. It’s also a rich source of diindolylmethane (DIM), which has estrogen-metabolizing properties.
