What does complex hyperplasia with atypia mean?
Many women who have symptoms of endometrial cancer (vaginal bleeding after menopause or abnormal menstrual bleeding) may have a biopsy that shows precancerous changes of the endometrium, called complex hyperplasia with atypia. Risk is high that 25 to 50 percent of these women will go on to develop endometrial cancer.

Endometrial hyperplasia most often is caused by excess estrogen without progesterone. If ovulation does not occur, progesterone is not made, and the lining is not shed. The endometrium may continue to grow in response to estrogen. The cells that make up the lining may crowd together and may become abnormal.
