I am a 64 year old female...I have been having sever pelvic pressure, and pain...no blood that I can see...had a pelvic and transvaginal ultrasound....dr said I had 10mm endometrial/uterine thickness..had hysteroscopy and d and c yesterday as outpatient....since i was still in recovery..the dr came out and told my sister ..she didn t find anything, no polyps or fibroids...I imagine she took a biopsy of the lining ...if there is no polyp or fibroid that you can see, does that rule out cancer or pre cancer..if there are no polyps do they still take biopsy of the lining...if she didn t see anything, can i be sure I am ok..then why is the thickness 10mm for someone my age...have appt to see her in 2 weeks
