I'm 28 and trying on a new bra, and my mum noticed a dimple in my left breast, (under side part), when I lifted my arm to look I noticed it's miss shaped than usual, we have high breast cancer in the family and she's worried, but I have lumpy breasts anyway so I don't know if I feeling new lumps or old ones I don't know, do you think I should just get this seen?
