Hi, I Recently Had A Hyteroscopy D&C Due To Endometrial

Hi,
I recently had a hyteroscopy D&C due to endometrial hyperplasia and abnormal bleeding. The lab report came back stating among others "stromal clumping", "glands exhibit atypical features with mild overcrowding" and "mild decidual change of stroma". Is this pre-cancer? Do I have what is called simple hyperplasia with atypical changes? My Obgyn has put me on provera and wants a repeat biopsy after 3 cycles.
