3 years post op- Irritation on healed breast implant scar, what could this be? Pimple or cyst? (photos)

41 year old woman 145 lbs. 3 years post op breast lift with implants. A couple weeks ago I noticed what I first thought may be a pie or cyst on my scar under my left breast. It’s gotten bigger and isn’t a pimple and I don’t think it’s a cyst either. Seems to almost have a small amount of blood pooling in that area.. Worried now and plan to call the doctor. Any thoughts welcome because he is known to brush things off.
