I had a breast scan a few months ago, as a lump appeared from nowhere...
I couldn't have had a better care system than in Pembury Hospital, and all was clear - despite the fact that I'm going through the same as you gals might do on occasions, which seems odd, but the docs said it's normal!
I seem to remember a serious advert which suggested that blokes should do all the feeling around to find anything, and I'm all for that too!
