Endometrial hyperplasia is an abnormal thickening of the uterine
lining (endometrium) that causes heavy vaginal bleeding and menstrual pain. If
endometrial hyperplasia is not treated, it may progress to endometrial
cancer.
Treatment for endometrial hyperplasia includes taking hormones,
having a dilation and curettage (D&C), having a procedure to destroy the
inner lining of the uterus (endometrial ablation), or having surgery to remove
the uterus (hysterectomy).
