Full Answer

Right Diagnosis indicates that ovarian cysts form each month due to the hormone fluctuations that women experience throughout their monthly menstruation cycle. These cysts are filled with tissue, fluid or blood. Most cysts go away by themselves, but some cysts remain in the ovaries and cause abnormal periods, infertility and abdominal pain.

Endometriosis is a condition in which tissue that normally grows inside of a woman's uterus grows outside the uterus, according to the Mayo Clinic. When endometriosis occurs in a woman's ovary, cysts called endometriomas form, irritating and inflaming the ovary. The treatments for endometriosis include prescription pain medications and oral or injectable hormonal contraceptives.

Benign ovarian tumors are solid, non-cancerous growths that form inside of ovaries. According to Core Physicians, the causes of benign tumors are not well understood. Surgery is usually required to remove benign tumors from an ovary before they damage the ovary. Sometimes, benign tumors cause so much damage to one or both of the ovaries that the ovaries must be removed.
