I don't know what the thickening showed. She told me it was slightly thickened, during an ultrasound examination, so was going to do a biopsy and remove a polyp - I was so terrified by that that I didn't ask about the thickening! I was quite overwhelmed by the experience of the biopsy/polyp removal which I found extremely uncomfortable/painful that I wasn't quite thinking straight enough to ask questions, I just wanted to get out of there!
Still waiting results but going back on Saturday for them to have a look with a camera.too
