A cyst or cancer can cause ovarian or pelvic pain in women after menopause. Although the formation of ovarian cysts in menopausal women is not very common, they still can occur in some women, relates WebMD. Some other symptoms of a cyst are lower back pain and weight gain.
When postmenopausal women have cysts, they may be at a higher risk for developing ovarian cancer, states the Office of Women's Health. For this reason, some doctors may choose to check if small cysts are growing larger or for signs of cancer. Postmenopausal women with cysts that cause pain or do not resolve on their own may need to have the cysts removed through surgery, explains the Office of Women's Health. Many women develop cysts, but most cysts cause no symptoms and resolve on their own without treatment. When cyst do cause symptoms, then treatment to relieve them may be necessary.
A benign ovarian cyst can become malignant. Ovarian cancer is another condition that can cause pelvic pain along with other symptoms like feeling tired, abdominal swelling and weight loss, reports the American Cancer Society. The treatment options for ovarian cancer can be surgery for the removal of the ovaries and chemotherapy, states the Mayo Clinic.
