I have a painful lump on the underside of my right breast. Is this cause for serious concern? I am only 19 years old.
I first noticed this lump just a few days ago, maybe a week... don't know if it's a sign of potential cancer, or what. Please help! I am just about to get married... don't want this to be a concern in my first year of marriage!
More info, potentially helpful:
- This has never appeared before.
- I am 100% NOT PREGNANT.
- I am not sexually active.
- I did recently have an IUD put in - the Mirena, which releases hormones.
