Your Mum is quite right--the most common and logical causes of breast pain are hormonal. Here's a web site with a lot of good information regarding breast pain:

I think you'll find it helpful. I would still recommend getting it checked out by a doctor,
however, just to be sure. It's what I'd do with my daughter. Better to be safe than sorry, I think.
Take care,

It's quite a hard lump and its sore to touch. It doesn't move from where it is now and it's easy to find the edges. I showed my Mum and she says its to do with my hormones. Is she right?
Wishing you all the best,
