assistant: Key Points
                    - Avoiding risk factors and increasing protective factors may help prevent cancer.    - The following are risk factors for ovarian, fallopian tube, and primary peritoneal cancer:         - Family history of ovarian, fallopian tube, and primary peritoneal cancer     - Inherited risk     - Hormone replacement therapy     -  Weight and height        - The following are protective factors for ovarian, fallopian tube, and primary peritoneal cancer:         - Oral contraceptives     - Tubal ligation     - Breastfeeding     - Risk-reducing salpingo-oophorectomy        - It is not clear whether the following affect the risk of ovarian, fallopian tube, and primary peritoneal cancer:         - Diet     - Alcohol     - Aspirin and non-steroidal anti-inflammatory drugs     - Smoking     - Talc     - Infertility treatment        - Cancer prevention clinical trials are used to study ways to prevent cancer.    -  New ways to prevent ovarian, fallopian tube, and primary peritoneal cancer are being studied in clinical trials.
                
                
                    Avoiding risk factors and increasing protective factors may help prevent cancer.
                    Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer.
                
                
                    The following are risk factors for ovarian, fallopian tube, and primary peritoneal cancer:
                    Family history of ovarian, fallopian tube, and primary peritoneal cancer    A woman whose mother or sister had ovarian cancer has an increased risk of ovarian cancer. A woman with two or more relatives with ovarian cancer also has an increased risk of ovarian cancer.        Inherited risk    The risk of ovarian cancer is increased in women who have inherited certain changes in the BRCA1, BRCA2, or other genes.     The risk of ovarian cancer is also increased in women who have certain inherited syndromes that include:            -  Familial site-specific ovarian cancer syndrome.     -  Familial breast/ovarian cancer syndrome.     -  Hereditary nonpolyposis colorectal cancer (HNPCC; Lynch syndrome).              Hormone replacement therapy     The use of estrogen -only hormone replacement therapy (HRT) after menopause is linked to a slightly increased risk of ovarian cancer in women who are taking HRT or have taken HRT within the past 3 years. The risk of ovarian cancer increases the longer a woman uses estrogen-only HRT. When hormone therapy is stopped, the risk of ovarian cancer decreases over time.     It is not clear whether there is an increased risk of ovarian cancer with the use of HRT that has both estrogen and progestin.        Weight and height    Being overweight or obese during the teenage years is linked to an increased risk of ovarian cancer. Being obese is linked to an increased risk of death from ovarian cancer. Being tall (5'8" or taller) may also be linked to a slight increase in the risk of ovarian cancer.
                
                
                    It is not clear whether the following affect the risk of ovarian, fallopian tube, and primary peritoneal cancer:
                    Diet    Studies of dietary factors including various foods, teas, and nutrients have not found a strong link to ovarian cancer.       Alcohol    Studies have not shown a link between drinking alcohol and the risk of ovarian cancer.       Aspirin and non-steroidal anti-inflammatory drugs    Some studies of aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) have found a decreased risk of ovarian cancer and others have not.        Smoking    Some studies found a very small increased risk of one rare type of ovarian cancer in women who were current smokers compared with women who never smoked.       Talc    Studies of women who used talcum powder (talc) dusted on the perineum (the area between the vagina and the anus) have not found clear evidence of an increased risk of ovarian cancer.        Infertility treatment    Overall, studies in women using fertility drugs have not found clear evidence of an increased risk of ovarian cancer. Risk of ovarian borderline malignant tumors may be higher in women who take fertility drugs. The risk of invasive ovarian cancer may be higher in women who do not get pregnant after taking fertility drugs.
