Some risk factors, like family history, can’t be changed. But making smart lifestyle choices can help lower your chances of being diagnosed with breast cancer.
Think breast cancer is out of your control? Think again. Research shows that even women with a strong family history can lower their risk of getting the disease by following some simple guidelines.
So, take prevention into your own hands with the science-backed strategies below. Can’t do them all? That’s okay! Doing just one of the first three on our list can cut your risk of breast cancer by 27%. And you can always add more steps when you're ready. Let’s get started.
Exercise can help you stay healthy today. It also lowers your risk of breast cancer over time. Women who walked about an hour each day had a 23% lower risk over time compared to women who moved less.
“It appears that exercise lowers inflammatory markers that are associated with breast cancer,” says Kristi DeSapri, MD, director of Bone and Body Women’s Health in Winnetka, Illinois. She’s also a professor of medicine at Northwestern Memorial Hospital.
Need a little motivation to get moving? Set a specific fitness goal. Some ideas:

Being overweight has been linked to breast cancer. It raises levels of hormones that can cause some kinds of breast cancer to form, says Dr. DeSapri. “For every 11 pounds a woman gains after age 18, her risk of breast cancer rises by 7%.”
For help losing weight, talk to your primary care provider (PCP). They can suggest tools to help you reach a weight that’s right for you. You might also be able to join a covered weight-loss program through the Blue KC Care Management app.

Alcohol can raise levels of cancer-causing hormones. The more you drink, the more your breast cancer risk goes up. For example, women who have one drink a day have about a 7% higher risk than nondrinkers. Women who have two to three drinks a day have about a 20% higher risk. To play it safe, cut back on alcohol. Better yet, skip it altogether.
Women who eat a healthy, plant-based diet have an almost 20% lower risk of breast cancer. That’s compared to those who eat a less healthy diet that’s high in refined grains and sugar.
“We know that a diet high in saturated fat causes your insulin to rise. And it raises your risk of being overweight or obese. These are all things linked to an increased risk of breast cancer,” says Dr. DeSapri.
Don’t want to give up meat? A plant-based diet doesn’t have to be meat free. Instead, focus on filling up on other, good-for-you foods. You’ll naturally eat less meat overall. Here are some healthy foods to put on your go-to list:
Nicotine and tobacco are linked to higher breast cancer risk. Smoking also raises your risk for heart disease, lung cancer, and more.
Quitting can be tough. But you don’t have to go it alone. Talk to your PCP about helpful tools like nicotine replacement therapy. Blue KC offers programs to help you quit through the Blue KC Care Management app.
There’s not enough evidence yet to know whether certain chemicals raise the risk of breast cancer. But groups like the Environmental Working Group (EWG) warn that some may play a role. These include:
These can include imaging tests like:
Talk to your doctor about the right screening schedule for you. Do you have a family history of breast cancer? If so, your doctor may also suggest genetic counseling. This can help you figure out a more personal prevention plan.
