Fibroids are found mainly in women in their forties. In most cases, fibroids cause no symptoms and require no treatment, although a doctor should check them. Depending on the size and location of the tumors, however, symptoms such as irregular bleeding, vaginal discharge, and frequent urination may occur. When fibroids cause heavy bleeding or press against nearby organs and cause pain, surgery or other treatment may be recommended. When a woman reaches menopause, fibroids are likely to become smaller, and sometimes disappear.
Endometriosis is another benign condition that affects the uterus.
It does not develop into cancer. Endometriosis is seen mostly in women in their thirties and forties. It occurs when endometrial tissue begins to grow on the outside of the uterus and on nearby organs. Treatment options generally include hormone therapy and surgery. Endometrial hyperplasia, also a benign condition, is an increase in the number of cells lining the uterus.
