At your young age, the lump is most likely benign, possibly a fibroademoma or a cyst. Pain is usually not a sign of breast cancer. However, the only way to know for sure is to get it checked out by your doctor. I'd highly recommend talking to your mother about it. Waiting and worrying about it won't make it any better, but taking action will. Any lump or change in the breast needs to be evaluated, so please get it checked out, OK?
Wishing you all the best,
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?
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.
