Common types of endometrial thickening include simple hyperplasia, complex hyperplasia, simplex atypical hyperplasia and complex atypical hyperplasia, explains Everyday Health. Women diagnosed with atypical hyperplasia have an increased risk of developing uterine cancer.

A transvaginal ultrasound can determine if endometrial thickening has occurred, states the ACOG. Additional tests, such as hysteroscopy and endometrial biopsy, detect the presence of cancerous cells. Progestin, given to women in the form of a vaginal cream, an injection, an oral medication or an intrauterine device, can treat endometrial thickening. Women experiencing irregular menstrual cycles may take birth control pills to regulate hormones. Women taking estrogen after menopause may have to take progesterone or progestin to prevent future endometrial thickening.
