The pathogenesis of ovarian cancer is unclear, but environmental and endocrine effects are the most important factors in the pathogenesis of ovarian cancer. According to its epidemiological and etiological surveys, its risk factors and high-risk groups are:
(1) Environmental factors: The high incidence of ovarian cancer among women in industrialized countries and in upper society may be related to high cholesterol in the diet. In addition, ionizing radiation and asbestos, talcum powder will affect the oocytes and increase the chance of inducing ovarian tumors, smoking and vitamin A, C, E deficiency may also be related to the incidence.
(2) Endocrine factors: Ovarian tumors often occur in non-maternal or non-fertility women. Pregnancy seems to have an antagonistic effect on ovarian tumors. It is believed that the repeated damage of epithelial ovarian epithelial cells caused by daily ovulation is related to the occurrence of ovarian tumors. In addition, breast cancer, endometrial cancer and ovarian tumors are more common, all three diseases are dependent on this hormone.
(3) Genetic and familial factors: About 20-25% of ovarian cancer patients have cancer patients in the immediate family.
Precaution
(1) Vigorously carry out propaganda, promote high-protein, high-vitamin A, C, E diet and avoid high cholesterol diet. High-risk women should use oral contraceptives for contraception.
(2) Women over the age of 30 undergo a gynaecological examination every year. High-risk groups should start census from an early age. B-ultrasound testing can be done to routinely check fetal globulin.
(3) Early detection and early treatment. Ovarian cystic tumor diameter greater than 6cm should be surgically removed, and routinely sent for pathological examination. Because benign tumors continue to grow, there is the possibility of malignancy. Ovarian solid tumors, regardless of size, should be operated as soon as possible, and frozen sections should be performed during surgery to determine the range of surgery. Patients with pelvic masses with unclear diagnosis or conservative treatment should undergo laparoscopy or laparotomy as soon as possible. All patients with breast cancer and gastrointestinal cancer should undergo routine gynecological examinations and follow-up to find metastatic cancer early.
