The high incidence of ovarian cancer in industrialized countries and upper-class women may be related to high cholesterol in the diet. In addition, ionizing radiation, asbestos and talcum powder can affect oocytes and increase the chance of ovarian cancer. Smoking and lack of vitamins A, C and E may also be related to the disease.

Reason 2: Endocrine factors.

Ovarian cancer mostly occurs in lying-in women or childless women, and pregnancy seems to have an antagonistic effect on ovarian cancer. It is considered that repeated epithelial shedding caused by daily ovulation is related to ovarian cancer. In addition, breast cancer and endometrial cancer are often associated with ovarian cancer, and all three diseases depend on this hormone.

Reason 3: Genetic and family factors.

About 20-25% of ovarian cancer patients have cancer patients in their immediate family members.
