Breast Cancer Screening: Empowering Women with Knowledge and Choices
Breast cancer screening is a cornerstone of preventive health care, but understanding the options, risks, and guidelines can often feel like navigating a maze. As a physician, I believe it is your job to be educated and armed with the information you need to make the best decisions for your health. My role is to provide the expertise and partnership to support you in that journey. Let’s talk about dense breasts, evolving screening options, and how to take control of your breast health.
What Does It Mean to Have Dense Breasts?
If you’ve been told you have dense breast tissue, you’re not alone. Dense breasts are common and simply mean there is more fibrous and glandular tissue compared to fatty tissue. However, dense tissue can make it harder to detect cancer on a standard mammogram, and it slightly increases the risk of breast cancer. Knowing this information is the first step in advocating for yourself and tailoring a screening plan that works for you.
Screening Options: Navigating What’s Right for You
For women with dense breasts, standard mammograms might not always provide the clearest picture. Fortunately, there are additional options to consider:
- Digital Breast Tomosynthesis (3D Mammography): Offers detailed imaging by taking multiple angles of the breast, improving cancer detection in dense tissue.
- Breast MRI: Particularly valuable for women at higher risk of breast cancer, MRIs provide detailed imaging without using radiation.
- Breast Ultrasound: This can be a helpful supplemental tool, especially for dense breast tissue, as it uses sound waves to capture images.
- Contrast-Enhanced Mammography (CEM): This advanced technique combines standard mammography with a contrast agent to highlight areas of concern, making it particularly effective for detecting small tumors.
- QT Ultrasound Imaging: A newer technique, QT Ultrasound provides high-resolution, 3D imaging without the use of radiation or compression. It is particularly promising for women with dense breasts, offering a comfortable and detailed alternative for early detection.
Each of these tools has its strengths, and choosing the right one depends on your unique breast cancer risk and screening goals.
When Should You Start Screening?
The age to begin breast cancer screening and the frequency of tests depends on your personal risk factors:
- Average Risk: Most guidelines recommend starting annual mammograms around age 40-50. Some suggest biannual screening based on your comfort and risk level.
- Higher Risk: If you have a strong family history of breast cancer, genetic mutations (like BRCA1/2), or a history of chest radiation, you may need to begin earlier. Additional tools like MRI may be recommended.
Calculating Your Breast Cancer Risk
Understanding your personal risk is empowering. Tools like the Gail Model
or Tyrer-Cuzick Model
assess factors such as family history, age, and reproductive history to provide a calculated risk of developing breast cancer. Knowing your risk score can help guide your decisions and advocate for a screening plan tailored to you.
Lifestyle and Cancer Risk: What You Can Control
It’s a common misconception that breast cancer risk is purely genetic. In reality, environmental factors, lifestyle choices, and epigenetics—the way your environment and behaviors influence your genes—play a significant role.
Chronic inflammation, often driven by poor lifestyle habits, can create an environment that supports the development and progression of cancer. Here are some actionable steps to reduce inflammation and lower your risk:
- Nutrition: Focus on a whole-food, plant-forward diet rich in antioxidants and anti-inflammatory foods like fruits, vegetables, nuts, seeds, and fatty fish.
- Exercise: Regular physical activity helps maintain a healthy weight, reduce inflammation, and support immune function.
- Stress Management: Chronic stress can fuel inflammation. Practices like mindfulness, meditation, and yoga can improve resilience and overall health.
- Sleep: Prioritize restorative sleep to allow your body to repair and regulate immune function.
- Avoid Toxins: Limit exposure to environmental toxins like smoking and excessive alcohol, which are linked to higher cancer risk.
While we can’t control every factor, these lifestyle changes can dramatically shift your cancer risk, empowering you to take charge of your health.
Hormones and Breast Cancer: What’s the Truth?
Let’s clarify an often-misunderstood topic: hormone therapy (HT). For women navigating perimenopause and menopause, HT can be an invaluable tool for quality of life and overall health. Decisions about HT should consider your personal and family health history, but it’s essential to understand that hormone therapy is not an automatic “risk factor” for breast cancer. Instead, the risks and benefits vary by individual, and the conversation should always center on shared decision-making between you and your doctor.
Why Education and Advocacy Matter
Breast cancer screening is not a one-size-fits-all process. It is a journey that evolves with your age, risk factors, and personal preferences. I encourage you to take an active role in your health by asking questions, knowing your breast density, calculating your risk, and advocating for the screening tools that are best for you. You have the power to be your own best advocate, and my job is to sit beside you, guiding and empowering you every step of the way.
A Personalized Plan for Lifelong Health
My ultimate goal is to help you preserve your healthspan—the years you spend active, independent, and free from chronic illness. Breast cancer screening is just one piece of that puzzle, but it’s a critical one. By staying informed and proactive, you’re setting yourself up for the best possible outcomes, not just for today but for the years ahead.
Remember, no question is too small, and no concern is too trivial when it comes to your health. Together, we can navigate this journey with clarity and confidence, ensuring that you feel empowered and supported at every turn.

You’ve probably seen it popping up in wellness podcasts, health stores, or even your friend's supplement cabinet: bovine colostrum. Marketed for gut health, immune support, and recovery, this early-life nutrient source for calves is now showing up in adult wellness routines. But is it worth your time and money? As a lifestyle medicine physician focused on women’s midlife health and longevity, here’s what I want you to know before you jump on the colostrum bandwagon. Let’s Start With the Basics: What Is Colostrum? Colostrum is the first form of milk produced by mammals (including humans) in the first few days after giving birth. It’s loaded with antibodies, growth factors, and immune-modulating compounds designed to jumpstart a newborn’s immune system and line the gut. Bovine colostrum—from cows—is the form used in most supplements. It's freeze-dried and packaged into powders or capsules, and often promoted for: Gut barrier support ("leaky gut") Immune system priming Exercise recovery Anti-aging benefits But let’s be honest: just because something has growth factors doesn’t mean it belongs in your Amazon cart. Does the Science Support It? Evidence in humans is limited— but not nonexistent. Some small clinical studies have shown potential benefits: Gut health: In people with NSAID-induced intestinal permeability ("leaky gut"), bovine colostrum has been shown to reduce damage and symptoms. Immune function: Some data in athletes suggests reduced upper respiratory infections. Exercise recovery: A few studies report improvements in performance, gut comfort, or muscle soreness—especially in endurance athletes. But these benefits aren’t guaranteed. And the quality and dosage of colostrum varies widely, with no standardized formulation across brands. So Should You Take It? Here’s where my clinical voice kicks in: Before you reach for colostrum, ask yourself: Have you addressed the basics? Are you sleeping? Managing stress? Eating fiber and whole foods? Getting enough protein? Building muscle? Moving your body? Supporting your gut with real food (not just powders)? If the answer is no—then colostrum is not your next step. You’re throwing powdered fuel on an engine that’s missing spark plugs. Do you have dairy sensitivity? Colostrum is a dairy product. Even if it's low in lactose, it may not be tolerated by everyone. Are you already taking quality foundational supplements? Vitamin D, omega-3s, magnesium, creatine, iron (when needed), and probiotics have stronger bodies of evidence for many women in midlife. When Might It Be Worth Trying? Colostrum might be a reasonable add-on if you: Have mild gut symptoms (especially post-infectious or stress-related) Are recovering from illness or antibiotics Train hard and experience frequent upper respiratory issues Want to support your immune system during travel or stress Even then, I recommend: A 2–3 month trial only after dialing in basics Choosing a third-party tested brand Tracking symptoms and benefits Cost, Hype, and the Bigger Picture Many women I work with are overwhelmed by supplement costs. Colostrum can run $50–100/month —and that adds up. So here’s what I tell my patients: Just because something is trending doesn’t mean it’s essential. And just because it works for someone on TikTok doesn’t mean it’s the right tool for your body right now. Your body is an incredible machine. When you give it rest, movement, nourishment, and support—it can do amazing things. Colostrum is not magic. It’s just one tool in a very big toolbox. Bottom Line Colostrum may hality sources. You’re not broken. You might just need a reset—not another powder.
