I found a lump in my left breast, it's hard and can be moved about. I'm worried it could be breast cancer, I know its unlikely due to my age but i also know that it isn't impossible. The lump is just under the skin near the nippel and doesn't feel as though it is attached. I've been scared to talk to my mum but i realise it could potentially be serious so i am going to talk to her and make an appointment at the doctors, I just wanted some feedback as to what you think it could be? thanks
