Dr. Kristi Funk, M.D., is a renowned breast cancer surgeon who has worked with celebrities from her Pink Lotus Breast Center in Beverly Hills. Dr. Funk is maybe best-known as the physician who performed Sheryl Crow and Angelina Jolie’s breast cancer surgeries years ago, and for her 2018 book, “Breasts: The Owner’s Manual.”

Jolie’s surgery made headlines in particular because she had a preventative double mastectomy without a breast cancer diagnosis, due to a genetic mutation she carried, called BRCA1. But while there’s a lot of attention paid to those with hereditary risk factors—like family history and genetic mutations (because women who have them see their risk increase so significantly)—Dr. Funk’s mission is to call attention to the more common cases.

“Eighty-seven percent of women diagnosed with breast cancer do not have a single first-degree relative with breast cancer,” she says in her book, “Breasts: The Owner’s Manual: Every Woman’s Guide to Reducing Cancer Risk, Making Treatment Choices, and Optimizing Outcomes”.

While it’s certainly true that incredibly healthy people who do everything right do still get breast cancer, her mission is to shed light on the scientific evidence that shows how changing your diet and lifestyle can help you reduce your risk.

“I think the biggest myth is that nutrition doesn’t matter,” she says. “[Breast cancer risk] has to do largely with diet and nutrition, alcohol, exercise, obesity, emotional stress, and environmental toxicity.” (If this sounds familiar, check out the eight pillars of living a Nutritious Life.)

Dr. Funk shares five simple changes you can make to your routine to reduce your breast cancer risk. Even if you’re not terribly worried about breast cancer prevention, these strategies all align with making you a healthier, happier person overall, so why not give them a shot?
