Endometrial cancer is a type of cancer that originates in the lining of the uterus, known as the endometrium. It is the most common cancer of the female reproductive system. Typically, endometrial cancer occurs when the cells in the endometrium begin to grow uncontrollably. This cancer is often detected early, as it may cause abnormal vaginal bleeding, particularly after menopause. Risk factors for endometrial cancer include hormonal imbalances, obesity, certain medications, and a family history of the disease. Diagnosis involves a combination of medical history, physical examination, and imaging tests, with confirmation through a biopsy. Treatment options vary based on the stage of cancer but commonly include surgery, radiation therapy, and chemotherapy. Regular check-ups and screenings are crucial for early detection and improved outcomes for individuals at risk of endometrial cancer.
