MD Anderson Oncologist Lists Three Daily Habits That Lower Breast Cancer Risk

Dr. Jennifer Litton, a breast medical oncology professor at the University of Texas MD Anderson Cancer Center, states that personal cancer risk varies due to genetics and environment. While individuals cannot change their DNA, they can modify lifestyle choices to lower that risk. Litton, who serves as the center's chief clinical research officer, outlines three specific habits that apply to everyone, regardless of genetic background.

The first habit involves eating a diet low in ultraprocessed foods. Litton describes this as maintaining a well-balanced intake of whole, plant-based items. She recommends limiting processed meats and sugary packaged products. Many oncologists, including those from Memorial Sloan Kettering Cancer Center, favor a Mediterranean style of eating. There is no single perfect diet, but reducing processed ingredients is a key step.

The second habit is engaging in regular physical activity. Litton advises patients not to wait for the perfect moment to start moving. She says, “If you can do five minutes here, do that. That’s better than doing nothing. Fit it in where you can.” Regular movement helps maintain a healthy body weight, boosts cardiovascular health, and supports bone health as the body ages.

The third habit is reducing or cutting out tobacco and alcohol. Tobacco use increases the risk for multiple types of cancer, including breast cancer. Dr. Suneel Kamath, a medical oncologist at the Cleveland Clinic, calls quitting smoking the single best health choice. He notes that there is nothing healthier in terms of behavioral choices. Regarding alcohol, experts agree that no amount is considered safe. Every drink contributes to a real increased risk for cancer, even if it does not require a complete cessation for all patients.

These three habits form the core of risk reduction. Other recommendations from experts include wearing sunscreen regularly and developing healthy ways to manage stress. Doctors also advise against relying on supplements and suggest asking about family health history. For those who have had cancer in the past, these same habits can make it less likely that the disease will return.

Dr. Julia Brockway-Marchello, a breast oncologist at Memorial Sloan Kettering Cancer Center, previously told TODAY.com that simple lifestyle changes have a big impact. The focus remains on actions individuals can control today to influence their long-term health outcomes.
