Gaining weight after a breast cancer diagnosis could increase the risk of dying from the disease.
Researchers at Johns Hopkins University studied over four thousand breast cancer patients. They found for every 11 pounds a patient gained after diagnosis, her risk of death went up 14 percent.
Women classified as obese had double the chance of dying compared to normal-weight women. Researchers say their findings confirm the importance of maintaining a healthy weight and regular exercise.
The study was presented at the American Association for Cancer Research meeting in Philadelphia.
