I had an unsuccessful hysteroscopy and biopsy on Friday under a general anesthesia due to my cervix being too far back and tight. They tried 3 different ways. I'm 5 years post menopausal with just 1 week spotting and pelvic cramps. I've now been put on a 2 week urgent referral for an mri I had an ultrasound which said my ovaries looked okay but the lining of my womb was 12. My question is will an mri pick up cancer or will I need a biopsy? Thanks
