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 know how people say, "Just drink some water and take a magnesium supplement" like it’s the answer to everything? Well… they’re not totally wrong. But like most good advice, the devil is in the details. Magnesium is one of the most essential minerals in the body, involved in over 300 enzymatic reactions , yet it remains one of the most commonly overlooked deficiencies in midlife women. And no, your annual bloodwork probably didn’t catch it. So What Does Magnesium Actually Do? Think of magnesium as a multitasking background assistant—it keeps the lights on and the gears turning across nearly every body system: Brain & Mood: Regulates GABA and NMDA receptors, supporting calm, focus, and resilience against anxiety and overstimulation. Muscles: Prevents cramping and twitching, supports strength and recovery, and reduces restless legs. Sleep: Plays a role in melatonin production and nervous system regulation. Bowel Function: Helps pull water into the colon to prevent constipation. Cardiovascular Health: Regulates blood pressure and helps with vasodilation. Hormone Balance: Assists in estrogen metabolism and combats insulin resistance. In short: if you’re exhausted, bloated, moody, foggy, tense, or irregular in your gut or cycle—magnesium deserves a spot on your radar. Why Is Magnesium So Important in Midlife? Estrogen and progesterone both influence magnesium levels. As hormone levels decline or fluctuate during perimenopause and menopause, so does your ability to retain and utilize magnesium. Add to that: Chronic stress (which depletes magnesium) Modern diets (often low in magnesium-rich whole foods) Medications like PPIs, diuretics, or certain antibiotics High caffeine, sugar, or alcohol intake (all increase magnesium excretion) And suddenly, a " borderline magnesium issue " becomes a perfect storm. Why Your Blood Test Might Not Show It Serum magnesium tests only reflect ~1% of total body magnesium. Most magnesium is stored in bone and tissue. So it’s very possible to have "normal labs" and still be clinically deficient. In practice, we go by symptoms, risk factors, and therapeutic response. Common Signs of Suboptimal Magnesium Trouble falling or staying asleep Anxiety or nervous system overactivation Fatigue or burnout that doesn’t resolve with rest Muscle cramps, spasms, or eye twitches Constipation Menstrual migraines or tension headaches Joint stiffness or tightness Sugar cravings or blood sugar crashes Best Food Sources of Magnesium Magnesium-rich foods include: Dark leafy greens (spinach, chard) Nuts and seeds (especially pumpkin seeds and almonds) Avocados Legumes Dark chocolate (yes, really!) Whole grains like quinoa and oats That said, many of us still fall short even with a healthy diet, especially during high-stress seasons or if absorption is impaired. Supplements: Which Type of Magnesium Is Best? Not all magnesium is created equal. Here are the forms we most often recommend: Magnesium Glycinate: Best for sleep, anxiety, and muscle relaxation. Gentle on the stomach.** Magnesium Citrate: Useful for constipation, but can cause loose stools at higher doses. Magnesium Threonate: May support cognitive function and brain health. Magnesium Malate: Good for energy and muscle pain, often used in fibromyalgia. We generally avoid magnesium oxide unless constipation is the only concern, as it’s poorly absorbed. **Mag Glycinate is generally my go to recommendation and what we take at our house Also, BLENDS can be good- but generally more expensive Dosing & Timing Most women benefit from 200–400 mg daily, depending on needs. Take it in the evening if you're targeting sleep or relaxation. Divide doses if taking more than 300 mg (e.g. AM + PM). Always start low and go slow, especially with citrate forms to avoid urgent bathroom visits. Final Thoughts If magnesium had better marketing, it would be a top-tier wellness darling. But because it’s quiet, essential, and boring on paper, we tend to overlook it. Yet for so many midlife women, magnesium is the missing link that helps all the other systems and strategies finally click. So if you're doing "everything right" and still feel off? It might be time to start taking magnesium!

"Is Ozempic safe?" "Do I have to be diabetic to use it?" "Will I regain weight if I stop?" "I eat well, lift weights, sleep, take hormones—and I still can't lose weight. What's going on?" These are some of the most common questions I hear from women in midlife. And they’re incredibly valid. For decades, the conversation around weight and health has been riddled with shame, assumptions, and surface-level advice. But we’re finally shifting into a new era—one that recognizes obesity as a chronic, complex disease, not a personal failure. One that looks at metabolism through the lens of hormones, inflammation, genetics, stress, and brain chemistry, not just calories in and out. And at the center of this shift is an exciting class of medications known as GLP-1 receptor agonists. What Are GLP-1 Medications? GLP-1 stands for glucagon-like peptide-1, a hormone your body naturally produces in the gut. It helps regulate blood sugar, insulin, and satiety (your sense of fullness). GLP-1s also slow gastric emptying and signal your brain to reduce appetite. Medications like semaglutide (Ozempic, Wegovy), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro) mimic this hormone and have been revolutionary for treating type 2 diabetes—and more recently, for metabolic syndrome and obesity. These drugs are not stimulants or fad diet tools. They are hormone-based medications with powerful metabolic and anti-inflammatory effects. Why Are GLP-1s So Relevant for Midlife Women? Midlife is a time of massive hormonal transition. Estrogen, progesterone, and testosterone levels shift dramatically in perimenopause and menopause. This impacts insulin sensitivity, body composition, lipid metabolism, sleep, inflammation, and brain function. Even women who have optimized their lifestyle—dialing in nutrition, strength training, sleep, and hormone therapy—may find themselves stuck. GLP-1 medications can be the missing piece for women who: Have insulin resistance or prediabetes that isn’t budging with lifestyle alone Carry weight disproportionately in the visceral (abdominal) area Are at increased cardiovascular risk due to family history, labs, or existing conditions Are experiencing significant inflammation or joint pain related to metabolic dysfunction Have a history of PCOS or gestational diabetes Are postmenopausal and noticing rapid changes in weight or metabolism These medications work synergistically with hormone therapy and can reduce inflammation, improve insulin sensitivity, and help shift body composition. For some women, they are as life-changing as starting estrogen. It’s Not Just About Weight Loss GLP-1s are being studied for NAFLD (fatty liver), cardiovascular protection, neurodegenerative disease, PCOS, and even addiction and mood regulation. The benefits go far beyond the scale. That said, when stubborn weight is a major barrier to living fully—whether due to physical discomfort, comorbidities, or psychological toll—helping a woman reduce weight safely and effectively can open the door to movement, joy, and hope. So, Who Should Consider a GLP-1? I don’t believe in prescribing these meds as a first-line for someone who hasn’t addressed the basics. That’s not judgment—it’s strategy. If you haven’t worked on: Blood sugar balance through real food Resistance training and daily movement Addressing sleep and circadian rhythms Managing stress and nervous system regulation Optimizing hormones, micronutrients, and gut health … then you’re not giving yourself the best shot at lasting change. But if you have done the work and still feel like your body is working against you—or you have serious metabolic risk factors— then GLP-1 therapy might be a wise and evidence-based next step. Some women use it briefly to reset. Others may need it long-term, just like hormone therapy. It’s not a crutch. It’s a tool. And for the right woman, it can be life-changing. Common Questions I Hear "Will I gain the weight back if I stop?" Maybe—but not always. If the lifestyle foundations are in place, many women maintain progress even after discontinuing. But some women have chronic conditions that benefit from ongoing use. That’s not failure—that’s biology. "Are there side effects?" Yes. The most common are nausea, constipation, or bloating early on. Starting slow, staying hydrated, and eating smaller portions helps. Rare but serious risks exist, including pancreatitis. A good clinician will walk you through these carefully. "Will I lose muscle?" You can—unless you’re strength training and eating enough protein. We talk a lot about this at Wondercreek. Protecting lean muscle is critical. "Is this forever?" Not necessarily. Some women use these meds to reduce inflammation, restore insulin sensitivity, and break a cycle. Others stay on them longer due to underlying metabolic dysfunction. Every plan is individualized. Final Thoughts GLP-1 medications aren’t for everyone. But they are not cheating, shameful, or lazy. They’re a legitimate, science-based treatment for a serious, chronic condition. In my practice, we focus on healthspan—not just lifespans. That means preserving function, preventing disease, and helping you feel energized, sharp, and resilient for as long as possible. For some women, GLP-1 therapy is one of the most powerful tools we have to get there.
