Changes in the cells that line the uterus are the principal indication of uterine cancer. When these changes make cells grow too fast, you get a tumor. The changes can be caused by problems with hormones, especially when there isn’t enough progesterone or too much ovary hormone. Diabetes, being overweight, and having a history of sickness in your family all raise the chance. Cut down on these things and catch them early with check-ups to make sure that treatment or protection works.
