Every October, pink ribbons appear everywhere, and women are reminded to schedule their mammograms.
That reminder matters.
Breast cancer screening can help detect cancer earlier, when it may be easier to treat. Knowing your personal risk and following an appropriate screening plan are important parts of taking care of your health.
But there’s another part of the breast cancer conversation that I don’t think gets nearly enough attention.
What can we do to lower our risk of developing breast cancer in the first place?
When I talk with women about breast cancer risk, many immediately think about genetics and family history. And of course, those things matter. Some women carry inherited genetic variants that substantially increase their risk, and a strong family history can absolutely change how we think about screening and prevention.
But here’s something that surprises many people: about 87% of women diagnosed with breast cancer have no first-degree relatives with the disease.
In other words, not having a mother, sister, or daughter with breast cancer does not mean breast cancer prevention is irrelevant to you.
And having risk factors does not mean cancer is inevitable.
We cannot control every variable. We can’t change our age, the genes we inherited, or much of our reproductive history. But there are meaningful factors we can influence.
I think that distinction is empowering.
Prevention isn’t about doing everything perfectly. It’s about understanding where we have some control and using that knowledge to improve our odds.
Move More—Even If You Don’t Have an Hour to Exercise
Exercise is one of the most consistently beneficial things we can do for our long-term health.
And breast health belongs in that conversation.
Physical activity has been associated with a lower risk of breast cancer, along with benefits for cardiovascular health, metabolic health, bone density, mood, cognition, and healthy aging.
But here’s the part I especially want women to hear:
You don’t have to become an endurance athlete for movement to matter.
A massive analysis involving more than 30 million adults found that even about 11 minutes per day of moderate-intensity physical activity—something as simple as a brisk walk—was associated with a lower risk of several cancers, including breast cancer.
Eleven minutes.
I love findings like this because they challenge the all-or-nothing thinking that keeps so many people from starting.
If you’re currently sedentary, don’t look at the recommendation of 150–300 minutes of moderate exercise per week and decide that anything less is pointless.
Start with 10 or 15 minutes.
Walk after dinner. Take the stairs. Put on music and move around the house. Build from there.
And as we get older, I also want women thinking about strength training.
Maintaining muscle isn’t just about appearance. Muscle is metabolically active tissue. It supports glucose regulation, mobility, bone health, independence, and resilience as we age.
So yes, walk.
But pick up some weights, too.
Fill Your Plate With Color
There is no single “anti-cancer food.”
I wish nutrition worked that way, but it doesn’t.
What we do see repeatedly is that overall dietary patterns matter. A diet rich in plants gives us fiber, vitamins, minerals, polyphenols, and other compounds that support metabolic and overall health.
So instead of obsessing over one superfood, think about variety.
Make cruciferous vegetables—broccoli, cauliflower, Brussels sprouts, cabbage, kale, and arugula—regulars on your plate.
Add deeply colored berries.
Eat beans and lentils.
Include nuts, seeds, and ground flaxseed.
And pay attention to fiber.
In a large analysis involving more than 700,000 women, each additional 10 grams of fiber consumed per day was associated with about a 7% lower risk of breast cancer.
That doesn’t mean adding exactly 10 grams of fiber suddenly makes someone 7% “protected.” Nutrition research is more complicated than that, and associations don’t prove that a single dietary change caused the difference.
But taken together with everything else we know about fiber and health, it gives us another good reason to prioritize fiber-rich whole foods.
And while we’re talking about food, I want to address something I still hear from women all the time:
You do not need to be afraid of soy.
The idea that women should avoid soy because it contains phytoestrogens has persisted for years. But phytoestrogens are not the same thing as human estrogen, and whole soy foods such as tofu,
tempeh, edamame, and soybeans are considered safe. Research suggests they may even be beneficial for breast health.
So if you enjoy tofu or edamame, you don’t need to remove them from your plate because you’re worried about breast cancer.
We Need to Be More Honest About Alcohol
This is probably the recommendation people least enjoy hearing.
Alcohol increases breast cancer risk.
And yes, that includes wine.
For years, alcohol—especially red wine—occupied this strange “maybe it’s actually healthy” space in our culture. But when we’re specifically talking about cancer risk, the conversation is much less reassuring.
The relationship between alcohol and breast cancer is dose-dependent: generally, the more alcohol someone drinks, the greater the risk.
Why?
Alcohol can influence estrogen levels, generate compounds that can damage DNA, and affect other biological pathways involved in cancer development.
Does that mean having a glass of wine guarantees you’ll develop breast cancer?
Of course not.
Risk doesn’t work that way.
But I think women deserve accurate information so they can make their own decisions. If reducing breast cancer risk is a priority, less alcohol is better.
You don’t have to approach this as an all-or-nothing decision either.
If you currently drink most nights, try having several alcohol-free nights each week. If two drinks is typical, make it one. If alcohol is mostly a habit rather than something you truly enjoy, consider whether you still want it to occupy the same place in your life.
Small changes add up.
Metabolic Health Belongs in This Conversation, Too
This is another reason I don’t like separating “weight,” “exercise,” “nutrition,” and “cancer prevention” into completely different conversations.
Our physiology doesn’t work in isolated categories.
After menopause, excess body fat—particularly visceral fat—can contribute to hormonal and metabolic changes. Adipose tissue also becomes an important source of estrogen after ovarian estrogen production declines.
Insulin resistance, chronic inflammation, body composition, physical activity, and metabolic health are interconnected.
This doesn’t mean we should tell women that breast cancer is caused by their weight. That is both inaccurate and unhelpful.
It means we should recognize that improving metabolic health may have benefits that extend well beyond what we see on the scale.
That’s why my goal with patients is rarely simply “lose weight.”
I’m much more interested in questions like:
Are we preserving muscle?
Are we reducing visceral fat?
Are glucose and insulin regulation improving?
Is she getting stronger?
Is she sleeping better?
Is she eating in a way she can actually sustain?
Those are much more meaningful markers of health.
What About Hormone Therapy?
I also think we need to acknowledge the question that is probably on the minds of many women navigating menopause:
What does all of this mean if I’m considering menopausal hormone therapy?
This deserves an individualized conversation—not a blanket statement that hormones are either “safe” or “dangerous.”
Breast cancer risk related to menopausal hormone therapy depends on several factors, including the type of hormones used, whether estrogen is used alone or with a progestogen, duration of therapy, a woman’s age and health history, and her baseline breast cancer risk.
For many appropriately selected women, hormone therapy can be an effective treatment for bothersome menopausal symptoms. But it should be prescribed thoughtfully, with an understanding of the individual woman rather than fear based on a headline from 20 years ago—or reassurance based on an Instagram post.
This is exactly where personalized medicine matters.
After a Breast Cancer Diagnosis, Health-Building Still Matters
There’s another group of women I don’t want to leave out of this conversation: breast cancer survivors.
Lifestyle doesn’t stop mattering after a diagnosis.
In a meta-analysis involving nearly 30,000 breast cancer survivors, physical activity after diagnosis was associated with a 16% lower risk of recurrence and a 23% lower risk of recurrence or breast-cancer-related death.
Again, observational data have limitations. We shouldn’t interpret those percentages as a guarantee that exercise will prevent recurrence.
But the larger message is difficult to ignore.
Movement matters.
Nutrition matters.
Maintaining muscle matters.
Metabolic and cardiovascular health matter.
And after everything the body has been through during cancer treatment, rebuilding strength and health deserves to be part of survivorship care.
Let’s Make Breast Cancer Awareness About More Than Mammograms
So this October, absolutely pay attention to screening.
Know your family history. Understand your individual risk factors. Talk with your healthcare provider about when mammography should begin for you and whether your personal risk warrants additional screening or genetic counseling.
But don’t stop the conversation there.
Go for the walk.
Lift the weights.
Eat more plants and fiber.
Enjoy whole soy foods if you like them.
Drink less alcohol.
Pay attention to your metabolic health.
And please don’t approach any of this from a place of fear or perfectionism.
We can do everything “right” and still develop cancer. Prevention is about reducing risk, not eliminating it. No woman should ever interpret a cancer diagnosis as evidence that she somehow failed to live healthfully enough.
That’s not how cancer works.
But when there are evidence-based choices that may improve our health and potentially lower our risk, I want women to know about them.
Early detection matters enormously. But I’d love to see Breast Cancer Awareness Month become a time when we talk just as openly about building health before disease develops.
Because screening helps us find breast cancer earlier.
Prevention asks whether we can reduce the chances of getting there in the first place.
And both deserve our attention.
