Can’t improve on that response. Don’t assume the worst - many lumps are benign - but the risk of ignoring any change in the breast simply isn’t worth it. You’d still be wondering. You need reassurance and only an expert will give you that - take the chance offered please. Good luck.
It could absolutely be harmless, lumps come in all shapes and sizes and sometimes there is no obvious lump. Get it checked out as soon as you can will always be our advice, stay away from google , easier said than done we all know but it won’t do you any favours and can tell you nothing at this stage. Try not to over think, see the Dr and take things from there X
I have just found a lump about the size of an olive in the area under the nipple region. It is hard and attached. Is there any way it could be something that is harmless?
