What is the probablity of a 17 year old developing endometrial cancer?

Very Low: The only time young patients, usually in their 20's get endometrial cancer, is due to a syndrome known as polycystic ovarian syndrome. In this disease, women are usually obese, have excess body hair, don't ovulate normally, bleed a lot and cannot get pregnant. If left untreated, it can lead to endometrial cancer. At 17yo, this is very rare and abnormal bleeding in this age group has other causes.
