Weight gain linked to breast cancer
Apr 7, 2011
A new report from Kaiser Permanente Division of Research shows a link between increased weight and breast cancer recurrence, according to CNN Health News.
Kaiser Permanente's findings apply specifically to women who have gained a significant amount of weight. Among 18,000 breast cancer survivors, those whose body weight increased by more than 10 percent had a 25 percent greater rate of breast cancer recurrence.
The research came from findings presented at a meeting of the American Association for Cancer Research on April 5.
Part of the explanation for the link may be due to age. People tend to gain weight as they get older and the risk for breast cancer also increases among women as they age.
Recent research has linked increased exercise with lower risks for breast cancer. Thus, the relationship between weight gain and breast cancer factors in many things such as exercise, diet and estrogen levels. Excess fat cells may increase estrogen, which can lead breast tissue growth into cancer, according to the news source.
