I was diagnosed w/stage IV endometrial cancer back in Aug 2012. So I did get to have an endometrial biopsy that did come back as malignant. Biopsy was not pleasant. I promised him I wouldn't scream, and I didn't. But I'm sure I left finger impressions on that exam table! Cancer or not, if you are looking at a hysterectomy, it wasn't that bad. I wasn't scared going into it because I had just had a hernia repair (that's how cancer was discovered). Minimal pain for me. I was in the hospital 3 days. Went home with a 10 lb lifting limit, which was annoying because I live alone. Grocery shopping was interest because 10 lbs is about the weight of a gallon of milk. Had to ask 'em to pack stuff light. I was off work 6 weeks. Would sit watching stupid daytime tv and thinking "if I can sit and stare at the tv, why can't I go to work and stare at my computer". Then I'd do laundry and have to take a nap. Ok, this is why I'm not at work... I was able to work through treatment, though.
Not quite sure if that answers some of your questions. If I missed the mark, let me know if I can clarify anything further for you. Hope your biopsy comes back negative.
