Wow I would be confused too...I just wrote somewhere else that the doctors seem to have a good handle on issues concerning OC...guess maybe not wrong but like in everything some are good and some don't really know...

Please just keep insisting and pushing the old saying the squeeky wheel gets oiled..if it takes a biopsy, cause one thing I have learned from this site is that is the absolute final answer if it is cancer, then push the issue till you get an answer...

Hoping you find your answers and you mom gets some relief
