I had a lump under my armpit/breast when I was a baby and was referered to hospital. It turned out to be a cyst and my parents were told it would disappear on it's own by the time I was 2. And sure enough it did.

My boy had lumps under his breasts on an occaission when he was a new born I was breastfeeding and told that it was down to my hormones passing through to him, sure enougth they dissapeared soon after. 

Hi girls, just went to the docs and she said it could be hormonal but to keep an eye on it - I am unsure why but it does seem to have gone down in the last few days which means it probably is hormonal.

thanks anyway for the advice. xx

My little boy was born with a little lump behind the nipple. The doctor told me it's very common and lots of little girls are born with them.  I think it's gone now - haven't felt it for ages and completely forgot about it!  All lumps and bumps should be investigated but I'm sure it's fine.  Hope this is a little reassuring.

I think I might do but see how it is tomorrow - I might even ring HV see what she says. I'll see how it is in the morning and go from there. thanks xx

I'm not sure, could just be something simple, but I would get a dr appt if I was you. Good luck hun. xx

Hey girls, wondered if you could help. DD is 8 months, she will be 9 months on the 18th of August and she has developed a lump under her left breast! it is like a nodule - thats what DH has said. Has anyone else experienced this and is it likely to be a cyst as i have read about them! thanks
