What is the cause of ovarian cancer?

The etiology of malignant epithelial ovarian tumors after menopause is not completely clear, which may be related to genetics, hormone level, long-term anovulation, BRCA gene mutation, lifestyle, environmental factors and other factors. Patients with genetic diseases such as ovarian cancer and breast cancer in their families may be at increased risk. 2. Hormone levels: decreased estrogen levels in postmenopausal women may increase the risk of ovarian malignant epithelial tumors. 3. Long-term anovulation: Such as polycystic ovary syndrome and other diseases, may lead to ovarian anovulation for a long time, increase the risk of ovarian malignant epithelial tumor.4.BRCA gene mutation: BRCA gene is a gene associated with breast cancer and ovarian cancer, BRCA gene mutation in women, the risk of ovarian cancer significantly increased. 5.Lifestyle: For example, long-term smoking, drinking, high-fat diet, etc., may increase the risk of ovarian malignant epithelial tumor.6.Environmental factors: long-term exposure to certain chemicals, such as asbestos, benzene, etc., may increase the risk of ovarian malignant epithelial tumor.7.Other factors: unmarried, barren, late childbearing, etc., may also increase the risk of ovarian malignant epithelial tumor. It should be noted that these are just some of the possible causes, and further research is needed to confirm the specific pathogenesis. For postmenopausal women, regular gynecological examinations should be performed in order to detect and treat ovarian malignant epithelial tumors early. At the same time, maintaining a healthy lifestyle, such as smoking cessation and alcohol restriction, balanced diet, moderate exercise, etc., can also help reduce the risk of ovarian malignant epithelial tumors.
