The Link Between Breast Cancer & Obesity In Blacks

Breast Cancer ribbon( — More and more researchers are shining a light on one of the secrets of preventing breast cancer: maintaining a healthy weight. The latest research shows that being overweight or obese significantly raises a woman’s chances of getting the disease — and it’s often a far bigger factor than genetics.

“Women think breast cancer is mainly related to family history,” says Melinda Irwin, PhD, associate professor of epidemiology and public health at Yale School of Medicine. “But in truth, only about 10 percent of cases are. That means 90 percent of breast cancer may be caused by environmental or lifestyle factors like weight.”

Packing extra pounds is one of the biggest risks for many types of cancer. In a groundbreaking study published several years ago in the New England Journal of Medicine, women who weighed the most died of cancer at a 62 percent higher rate than those who were slimmer. The researchers blamed excess weight for up to half of all deaths from breast cancer alone.

“The scary thing is that even as more and more research shows a link between weight and cancer, women are becoming heavier and less active,” Irwin says. She and other experts worry that this could lead to a rise in cancer cases down the road.

Yet for all the dire warnings, women aren’t getting the message. Only 8 percent of people in the United States realize that being heavy increases cancer risk, reports the American Cancer Society; 92 percent have no idea. One reason for this: Doctors rarely discuss weight during the typical office visit. Just 11 percent of overweight patients received diet counseling from their MDs, concluded a study by Robert Wood Johnson Medical School in New Brunswick, New Jersey.

“Most doctors find dealing with weight frustrating,” says Jeanne Ferrante, MD, a researcher at the school who did a follow-up study on physician attitudes. “That’s partly because a lot of patients don’t like to talk about it. But doctors also have negative attitudes.”
