When Does Endometrial Hyperplasia Become Cancer?

It appears more likely to return if you are overweight with a body mass index (BMI) of more than 35. Atypical hyperplasia can turn into cancer of the womb. 20 years after diagnosis, around 28 out of every 100 women diagnosed with atypical hyperplasia will develop cancer of the womb.

Does a thickened endometrium always mean cancer?

Thickened womb lining

Endometrial hyperplasia is a non cancerous (benign) condition where the lining of the womb becomes thicker. You have a higher risk of developing womb cancer if you have this thickening, especially if the extra lining cells are abnormal.

What percent of endometrial hyperplasia is cancer?

Simple atypical hyperplasia turns into cancer in about 8% of cases if it's not treated. Complex atypical hyperplasia (CAH) has a risk of becoming cancer in up to 29% of cases if it's not treated, and the risk of having an undetected endometrial cancer is even higher.
