Earlier tonight I found a hard, slightly mobile, pea sized lump which is tender to touch. I have also recently noticed some marks on the same breast which resemble stretch marks but are not discoloured (I'm 23 and haven't put on any weight, so can't think of a reason why my breast would be growing to cause this?).
slightly panicking as I cannot get an appointment with my GP until next week.
any advice would be greatly appreciated x
