Breast Health Decoded: Dense Breasts, Risk Factors, and the Screening You Deserve.
Anna Harrelson • December 20, 2024
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.

As a menopause specialist, lifestyle medicine physician, and a perimenopausal woman with a family history of metabolic syndrome, I have a deep, personal and professional investment in the role of metabolic health during menopause. Preventing insulin resistance and diabetes is not just a clinical goal—it’s something I think about daily. A groundbreaking meta-analysis recently published by The Menopause Society sheds light on an area that has long been debated: the relationship between hormone therapy (HT) and insulin resistance. This research reviewed 17 randomized controlled trials encompassing over 29,000 participants, finding that menopausal hormone therapy—including both estrogen alone and estrogen plus progestogen—can significantly reduce insulin resistance in healthy postmenopausal women. This study is not just an academic curiosity. It has real, actionable implications for midlife women who are trying to navigate the complex landscape of hormonal changes, weight shifts, and metabolic health challenges. Let’s break down what this means, why it matters, and how we can apply this research to both clinical decision-making and personal wellness. Understanding Insulin Resistance and Menopause Insulin resistance is a condition where cells in the body become less responsive to insulin, leading to elevated blood glucose levels, increased fat storage (especially around the midsection), and a greater risk for developing type 2 diabetes. Estrogen plays a key role in regulating glucose metabolism, insulin sensitivity, and fat distribution, which is why the transition into menopause—when estrogen levels drop—often correlates with increased abdominal fat and metabolic dysfunction. Many women find themselves frustrated, feeling like they’re doing everything right from a lifestyle perspective, only to see weight accumulate in their midsection. What used to work no longer does, and this can be incredibly disheartening. While medications exist that may seem like a quick fix, understanding the role of hormones and lifestyle remains critical in long-term metabolic health. What the Study Found This meta-analysis provides strong evidence that hormone therapy may not only alleviate traditional menopause symptoms but could also serve as a protective factor against insulin resistance. Here’s what stood out: - Reduction in Insulin Resistance: HT was associated with a statistically significant reduction in insulin resistance markers across all included studies. - Estrogen Alone vs. Estrogen + Progestogen: While both forms of HT improved insulin sensitivity, estrogen-only therapy showed slightly more pronounced benefits. - Route of Administration Matters: Both oral and transdermal (patches, gels) routes showed efficacy, but different formulations may impact metabolic outcomes uniquely. - No Increased Diabetes Risk : Contrary to outdated concerns, this research did not find an increased risk of diabetes with hormone therapy use. The Bigger Picture: Cortisol, Stress, and Metabolic Dysfunction While estrogen clearly plays a key role in metabolic regulation, it’s not the only factor at play. Stress—and its impact on cortisol—also significantly influences insulin sensitivity. Chronic stress, disrupted circadian rhythms, poor sleep, and lifestyle factors all contribute to increased insulin resistance, making menopause an even more vulnerable period for metabolic dysfunction. Additionally, many women unknowingly exacerbate metabolic issues by under-eating and over-exercising. Chronic caloric restriction and excessive cardio without adequate strength training can drive up cortisol levels, leading to worsened insulin sensitivity, increased fat storage, and hormonal imbalances. One of the most powerful tools for metabolic health is muscle. Muscle acts as a “sink” for glucose, helping regulate blood sugar and improve insulin sensitivity. The more muscle mass we maintain, the better our glucose control. For those struggling with insulin resistance or unexplained weight gain, a two-week trial using a continuous glucose monitor (CGM) can provide valuable insights into how their body processes glucose, helping them make more informed dietary and lifestyle decisions. Keeping blood sugar balanced and avoiding spikes is key to reducing insulin resistance and maintaining optimal metabolic health. What Does This Mean for You? If you are a perimenopausal or postmenopausal woman concerned about metabolic health, here are key takeaways: 1. Hormone Therapy Isn’t Just for Hot Flashes – If you’re struggling with weight gain, insulin resistance, or metabolic shifts, HT may be a powerful tool to help stabilize your metabolism and improve insulin sensitivity. 2. Individualized Care is Essential – This study reinforces the importance of personalized medicine. The “best” HT formulation varies by individual risk factors, medical history, and metabolic profile. 3. Lifestyle Still Matters – HT can be part of the solution, but optimizing metabolic health also requires dietary adjustments, regular strength training, sleep hygiene, and stress management. 4. Not Everyone Can or Should Take HT – While HT has clear benefits, not all women are candidates. That doesn’t mean they are destined for insulin resistance or diabetes. Genetics, lifestyle, and overall metabolic health play major roles, and there are still many ways to reduce risk without hormone therapy. 5. Advocacy is Key – Many clinicians still view HT through the outdated lens of the Women’s Health Initiative (WHI) study from the early 2000s. You deserve care informed by current science. If your doctor dismisses HT outright, it may be time for a second opinion. Final Thoughts: Staying Ahead of the Research This research reinforces what I—and many other menopause specialists—have suspected for years: the impact of estrogen on metabolic health extends far beyond its traditional role in symptom management. For those of us who are determined to prevent insulin resistance, diabetes, and metabolic disease in midlife and beyond, these findings should be front and center in our healthcare discussions. As a menopause physician who tries to stay up to date with the latest research, I am here to provide informed, evidence-based guidance. If you’re navigating perimenopause or menopause and want to take a proactive approach to your health, I’d love to help you explore your options, including whether hormone therapy could be beneficial for you. Because menopause isn’t just about surviving the transition—it’s about thriving in midlife and beyond.
Hot flashes and night sweats get all the attention when it comes to menopause, but what about the symptoms that no one warns you about? The ones that leave you wondering if you have 27 different diagnoses when, in reality, it’s all just perimenopause? If you’ve been feeling off and struggling to connect the dots, you’re not alone. Let’s break down some of the lesser-known symptoms of perimenopause and menopause, why they happen, and what you can do about them. The Wild Ride of Hormonal Shifts: It’s Not Just Declining Estrogen Before we dive in, let’s get one thing straight: menopause symptoms aren’t just about a steady decline in estrogen, testosterone, and progesterone. It’s the erratic, unpredictable rollercoaster of hormonal shifts during perimenopause that wreaks the most havoc. Many symptoms that peak during perimenopause stabilize once estrogen levels even out after menopause. However, that doesn’t mean they disappear completely—even with menopausal hormone therapy (MHT), some symptoms persist, just with less intensity. The Symptoms No One Talks About (But We Should) 1. Breast Size Changes Your breasts might feel fuller, lumpier, or even shrink as estrogen and progesterone levels fluctuate. Many women notice that their cup size changes due to changes in breast tissue composition and fat distribution. Tenderness is also common, especially in perimenopause when hormone levels are fluctuating wildly. 2. Burning Mouth Syndrome Yes, this is a real thing. Some women experience a burning sensation in their tongue, lips, or gums, likely due to declining estrogen affecting nerve function and saliva production. 3. Electric Shock Sensations Ever felt like you’re being zapped by an invisible force? Sudden, brief electrical shock sensations are a weird but real symptom of menopause, thought to be linked to nerve instability caused by estrogen fluctuations. 4. Skin Crawling and Itchiness If your skin suddenly feels like bugs are crawling on it, or you’re itching more than usual, fluctuating estrogen could be to blame. Estrogen plays a role in collagen production and skin hydration, so its decline can cause dryness, sensitivity, and that creepy-crawly feeling. 5. Digestive Issues Bloating, gas, changes in bowel habits—estrogen and progesterone directly impact gut motility, microbiome balance, and inflammation. Perimenopause often brings IBS-like symptoms that settle once hormone levels stabilize. 6. Bladder and Urethral Symptoms Frequent UTIs, urgency, or even a weird tingling sensation in your urethra? The bladder and urethra are estrogen-sensitive tissues, so they can become irritated, dry, and inflamed with hormone changes. 7. Body Odor Changes Some women notice their scent changes, even if they haven’t switched deodorants. Shifts in hormone levels affect sweat gland activity, sometimes making body odor stronger or just different. 8. Tinnitus (Ringing in the Ears) Fluctuations in estrogen impact circulation and nerve function, which can contribute to ringing or buzzing in the ears. 9. Increased Histamine Sensitivity Ever feel like your allergies are suddenly worse? Estrogen affects mast cells, which are responsible for histamine release. Fluctuating estrogen can make you more prone to hives, flushing, and histamine-related reactions. 10. Anxiety and Sudden Panic Attacks You were never an anxious person before, so why does it feel like you’re constantly on edge? Estrogen directly impacts neurotransmitters like serotonin and dopamine, and when it swings wildly, so does your mood. 11. Joint Pain and Stiffness Estrogen has anti-inflammatory properties, so its decline contributes to increased joint pain, stiffness, and even the onset of inflammatory conditions like frozen shoulder. How Hormone Therapy and Lifestyle Changes Can Help While many of these symptoms improve as hormones stabilize, the reality is that you don’t have to suffer through them without support. Let’s talk about what actually helps. Menopausal Hormone Therapy (MHT): Replacing estrogen, progesterone, and even testosterone can help significantly with many of these symptoms, especially those related to nerve function, skin, and bladder health. However, MHT won’t make all symptoms vanish overnight—it’s about stabilizing the hormonal rollercoaster and reducing severity. Oral Contraceptives for Perimenopause: If you’re still cycling and experiencing extreme symptom fluctuations, oral contraceptives can suppress ovulation and override hormonal chaos, making symptoms much more manageable. Lifestyle Adjustments That Matter: Anti-Inflammatory Diet: Eating whole, nutrient-dense foods supports gut health, reduces histamine sensitivity, and minimizes inflammation that contributes to joint pain and digestive issues. Strength Training & Movement: Regular exercise helps with joint pain, muscle loss, and hormone balance. Strength training in particular helps combat estrogen-related muscle deterioration. Hydration & Electrolyte Balance: Dehydration can make symptoms like dizziness, joint pain, and histamine intolerance worse. Stress Management & Sleep Hygiene: Poor sleep and chronic stress exacerbate many menopause symptoms. Prioritizing rest and relaxation is crucial. You’re Not Broken—You’re in Perimenopause If you’ve been dismissed by doctors, told your symptoms are unrelated, or prescribed multiple medications for what is actually a single hormonal transition, know this: you are not alone. Perimenopause and menopause can make you feel like a stranger in your own body, but there is hope. Understanding what’s happening and having a plan—whether that includes MHT, lifestyle modifications, or a combination of both—can make all the difference. If you’re struggling and want personalized support, I’m here to help. Let’s work together to navigate this transition with clarity, confidence, and solutions that actually make a difference in your life. Because you deserve to feel like you again.
