Women who maintain a healthy weight are more likely to survive breast cancer.
Researchers in Denmark followed a group of breast cancer patients for 30 years, looking at their health outcomes as well as their weight.
Women with a body mass index higher than 25 were older and had more advanced disease when they were diagnosed -- compared to women with a lower BMI.
Overweight women also had an increased risk of dying from breast cancer.
The study was presented at the annual San Antonio Breast Cancer Symposium, Dec. 9-13, 2009.
