A malignant tumour of the ovary, which occurs especially after the menopause.
Malignant neoplasm of the ovary, occurring m women most often between the ages of 40 and 60. Symptoms, which often do not appear until the disease is advanced, include abdominal discomfort, vaginal bleeding, irregular or excessive menstrual bleeding, constipation, and urinary problems. Treatment is by surgery, irradiation, and chemotherapy.
Any malignant growth in an ovary. About 85% to 90% of ovarian cancers arise from the surface epithelium of the ovary. In the U.S. in 2008, the American Cancer Society estimated there would be about 21,600 new patients diagnosed with ovarian cancer, and about 15,200 deaths from the disease. Most cases (70%) are diagnosed when the disease is already at an advanced stage because early detection methods are still unsatisfactory. The early symptoms of the disease are often nonspecific, and often mimic irritable bowel: constipation, vague abdominal pain, bloating, among others. Initial laboratory studies (routine blood tests and x-rays) are often unremarkable.
