Anyone have Adenoma malignum?


I am new to this forum. I just saw a GYN oncologist and they want to do a cone biopsy as they don’t know if i have adenomyosis or Adenoma malignum. Ive been reading the posts in here for a few days, which is helping, thank you!
I was wondering if anyone in here has Adenoma malignum? I have been told it is very rare, and very hard to diagnose.
Anyone that may have this, was it hard for them to diagnose you? If you dont mind me asking what was your experience through all this?
I have been healthy my whole life till just over a year ago and now lots of medical stuff going on and no one can tell me whats wrong.
Glad i found this forum as it helps to hear what others are going through.
Thoughts and best to all!
