My name is Ron I am exremely worried about my wife,Susan. She has just had a pelvic ultrasound and has been told that the endometrial lining has thickened to 40 mm. She is scheduled to see a gyno next week to arrange a scope and a biopsy. The indication from the doctor was that it was either endometrial displaysia or cancer with little other option. Has anyone had thickening to this extent and if so what was the result. Thanks for your help I'm really not sure where my head is at the moment ,I am also a cancer survivor having had an aggressive stage three colon cancer with 6 lymph glands involved, somehow I managed to beat it and have been clear for 8 years. I can't bear the thought of my wife having to go down the same road,thanks for any help you can give me Ron.
