Hi unfortunately none of us can tell you what might or might not be cancer but as I read in your other mail you've done the right thing by seeing your doctor and you're on the road as it were! I had 2 small lumps at the top of my boob which is how I ended up getting investigated. They turned out to be harmless cysts but an indeterminate area of thickening was diagnosed from the mammogram as a tumour and i also had DCIS. If I hadn't felt the cysts who knows how long it would have been till I realised something was wrong ?
I don't say this to frighten you but to reassure you that you've done the right thing, this is the worst bit, waiting for info but the lovely ladies here will help you through it all. Please don't torture yourself worrying without reason. You will have results soon and can use your strength for what, if anything, comes next. Be strong x
