Sorry you're having to go through this. As we're a breast cancer site, we don't really concentrate or feel comfortable talking about other breast issues, like mastitis. However, lumps in your breast are always a concern, since they can turn out to be cancer. I'd suggest you get a referral to a breast specialist. S/he can give you a thorough workup, try to discover why you've had two bouts of mastitis, and figure out what these various lumps are that you're feeling. So please ask you regular doctor for a referral; and if you don't have a regular doctor, ask at your nearest hospital for names of breast specialists. Good luck - PJH
