Ovarian cancer genetic testing can guide treatment for individuals, and for female members of the family, they need to know whether there is some heredity and whether they need to follow up to prevent the occurrence of ovarian cancer. Of the three major gynecological cancers, including cervical cancer, endometrial cancer and ovarian cancer, about 70% of ovarian cancers are found to be late and have no specific and obvious symptoms. Ovarian growth sites are deeper, making early detection difficult. Overall, ovarian cancer treatment is less effective than cervical cancer and endometrial cancer. About 70% of ovarian cancer patients will recur within 2-3 years after treatment. Surgery is the first treatment option for ovarian cancer, and if there is a chance of surgery, complete surgery is needed, followed by standardized chemotherapy. Ovarian cancer may have BRCA1 and BRCA2 gene mutations. Currently, there are targeted drug therapy with better treatment effect, which is a big progress in ovarian cancer research, but targeted therapy has better effect on patients with gene mutations. Ovarian cancer genes are hereditary, and female relatives, such as daughters, need to be tested for them if they carry the genes. If carrying the above mentioned gene, prophylactic oophorectomy is recommended around the age of 40-45.
