A common birth control device is effective in treating early-stage endometrial cancer in morbidly obese and high-risk surgery patients, said Georgia Health Sciences University Cancer Center researchers, and could lead to a cost-effective treatment for all women with this cancer type. Endometrial cancer, which starts in the lining of the uterus, is the third most common gynecologic cancer, striking more than 47,000 American women every year, particularly the obese. “Total hysterectomy, sometimes with removal of lymph nodes, is the most common treatment for this type of cancer. But women who are morbidly obese or who have cardiac risk factors are not good candidates for surgery,” said Dr. Sharad Ghamande, a gynecologic surgeon and oncologist at the GHSU Cancer Center, Chief of the Section of Gynecologic Oncology at the Medical College of Georgia, and principal investigator on the study.
