Which of the following is a risk factor for endometrial cancer?

Explanation:
Obesity is a risk factor because extra adipose tissue increases estrogen levels through peripheral conversion of androgens to estrogen. This unopposed estrogen stimulates the endometrial lining, leading to proliferative buildup and a higher chance of malignant transformation. Early menopause reduces lifetime estrogen exposure, so it’s not a risk factor. Combined oral contraceptives add progestin, which opposes estrogen's effects on the endometrium and lowers risk. Regular exercise also helps lower risk by reducing obesity and improving metabolic health.
