Obesity Obesity is associated with an increased risk of developing gynecologic cancers such as
endometrial and
ovarian cancer. For
endometrial cancer, every 5-unit increase on the BMI scale was associated with a 50-60% increase in risk. Type 1 endometrial cancer is the most common endometrial cancer. As many as 90% of patients diagnosed with Type 1 endometrial cancer are obese. Although a correlation between obesity and
ovarian cancer is possible, the association is predominantly found in low-grade subtypes of the cancer.
Genetic mutations Genetic mutations such as the
BRCA1 and
BRCA2 have been strongly linked to the development of ovarian cancer. The BRCA1 mutation has been shown to increase the risk of developing ovarian cancer by 36% - 60%. The BRCA2 mutation has been shown to increase the risk of developing ovarian cancer by 16% - 27%. A clear link between human papilloma virus and cervical cancer has long been established, with HPV associated with 70% to 90% of cases. Persistent human papilloma virus infections have been shown to be a driving factor for 70% to 75% of
vaginal and
vulvar cancers. Current women smokers are twice as likely to develop cervical cancer compared to their non-smoking counterparts. The cervical epithelium's DNA is damaged due to smoking. Through similar mechanisms, women smokers have also been found to be 3 times more likely to develop vulvar cancer. Smoking has also been associated with an elevated risk for vaginal cancer. Some studies have shown that 1 in every 7 couples will fail to conceive due to infertility problems. Infertile women are at a higher risk of developing ovarian cancer and endometrial cancer when compared to fertile women. == Treatments ==
