Uterine cancer, also known as endometrial cancer, is the most common type of cancer that affects the female reproductive organs. More number of women are affected by uterine cancer than cervical cancer or ovarian cancers. Uterine cancer develops in the lining of the uterus — the endometrium.
The risk of endometrial cancer increases as you get older. Things that affect hormone levels, particularly estrogen, can increase a woman’s chance of getting uterine cancer. These include taking estrogen after menopause, tamoxifen for breast cancer treatment, and birth control pills. A higher number of menstrual cycles (over a lifetime), never becoming pregnant, being obese, and having certain ovarian tumors or polycystic ovarian syndrome can increase the risk, too.
