The most common symptoms of ovarian cancer include changes in bowel habits, abdominal bloating, weight loss, pelvic discomfort and frequent urination, explains Mayo Clinic. Symptoms are often vague and usually do not occur until the cancer is advanced.
Ovarian cancer may also cause patients to feel full quickly while eating, according to Mayo Clinic. Factors that increase the risk of ovarian cancer include inherited gene mutations, age, smoking, estrogen hormone replacement therapy and fertility treatments. Women who have never been pregnant, use intrauterine devices, started menstruation before age 12, stopped menstruation after age 52 or have polycystic ovary syndrome are also at a greater risk for ovarian cancer.
