Endometrioid adenocarcinoma is a common type of uterine cancer that appears in the glandular cells of the uterine lining, according to Memorial Sloan Kettering Cancer Center. About 75 percent of uterine cancer cases can be attributed to endometrioid adenocarcinoma, however, as most cases are discovered early, the disease has a high cure rate. Surgery is the most common treatment option for endometrioid adenocarcinoma and other treatments include radiation, chemotherapy and hormonal therapy.
The most common symptom of endometrioid adenocarcinoma is abnormal vaginal bleeding, Memorial Sloan Kettering Cancer Center reports. Other symptoms include pain or difficulty urinating, and pain during sexual intercourse. Additionally, women in their 30s and 40s may experience bleeding between periods, and some patients report an unusual vaginal discharge that is pink, white or watery. Any vaginal bleeding that occurs after menopause should be checked out by a doctor as soon as possible.
Endometrioid adenocarcinoma and other types of uterine cancer tend to develop after menopause, according to Memorial Sloan Kettering Cancer Center. Of the nearly 50,000 American women who are diagnosed with uterine cancer each year, most of them are between the ages of 50 and 60. In fact, approximately one in ten postmenopausal women is diagnosed with some form of uterine cancer.
