Endometrial cancer is a type of cancer that begins in the lining of the uterus, known as the endometrium. It is the most common cancer of the female reproductive system and often occurs after menopause. Symptoms may include abnormal vaginal bleeding, pelvic pain, and changes in menstrual cycles. Risk factors for developing endometrial cancer include obesity, hormonal imbalances, and a family history of the disease. Early detection through regular check-ups can improve treatment outcomes. Treatment options typically involve surgery, radiation, and hormone therapy, depending on the stage and severity of the cancer.
