Calcifications

Hi,

Sorry to post but I am a 34 year old overthinker just after some advice. About 3 years ago I found a tiny lump which felt like a tiny bit of grit under my skin. The hospital did an ultrasound, said it was a calcification and not to worry.

Upon examining my breasts (which I do monthly) I have noticed it again and it feels bigger. Still tiny but definitely a bit bigger. 

Is this cause for concern. I don't want to waste a doctor's time looking at something they have already seen.

Thanks xx
