Study Finds Link Between Obesity and Breast Cancer Mortality

Reuters reports on a new study to be presented at the annual meeting of the American Society of Clinical Oncology (ASCO) that has shown that obese pre-menopausal women are at a 34% higher risk of dying from breast cancer than their non-obese counterparts. “Obesity has been linked with an increased risk for many of the most common cancers, including breast, colon, and high-grade prostate cancers. Obesity is also associated with increased levels of estrogen,” which may explain why pre-menopausal obese women are most affected. Researchers found that the study found no connection between obesity and increased risk of death in post-menopausal women or in patients whose breast cancer was estrogen receptor negative, “meaning the tumors do not rely on the hormone to grow.”
