This pilot clinical trial studies whether obese stage I-II endometrial cancer survivors or patients with atypical hyperplasia (abnormal cells in the lining of the uterus) would go see a weight loss specialist if it was recommended by their cancer doctor. Excess body weight or obesity is one of the most common contributors to (causes of) endometrial cancer. Over two-thirds of women who have survived endometrial cancer are obese. Complications of obesity, such as heart disease are often more dangerous than the cancer itself. A weight loss of even 5-10% of excess body weight is associated with improved health. Often, meeting with a doctor or person who is an expert in weight loss (bariatric specialist) is the best way to lose weight and keep it off. Endometrial cancer survivors or patients with atypical hyperplasia who go see a weight loss specialist recommended by their doctor may be able to achieve a healthier body weight.
