I know it doesnt help to get these responses, however I know I would want to know too, so I will tell you my story. My breast was much bigger than the other and I turned out having something in the duct, they thought it was maybe cancer but it turned out not to be after I had lumpectomy. I think its very likely your duct can have something blocking in there, but you can't tell without US or other tests. Is it leaking at all any fluid? Just wait and see....Im sure you will be ok honey........its a real bummer waiting for this stuff....keep me posted please...Madge
