Found a hard lump on the bone of my sternum- concerned?

I’m a 22 year old female and today I noticed for the first time a small lump (about the size of a pea) near the centre of my chest. It feels like bone and is on my sternum. It’s only on one side and I’m certain it wasn’t there before (at least not since a few weeks ago). 

I’ve never had any serious physical health conditions but cancer does run strongly in my family.

Should I be worried and get it checked out, or is it likely just a weird bit of bone growth?

  • Hi, 

    I found lump on right side more on like my chest I don't know if this is the sternum? Cancer runs in my family but I spend so much time at the doctors that I feel like they think I just go for the sake of it! Trying to avoid doctors but I don't know if I should treat it as urgent or not?
