Staph infection. Would this affect me if I wanted to get breast implants later in the future?

Dear kvylaa98,
as long as you don't have an active infection, you should be fine. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Plenty of time has passed. You should be fine to get implants. Oral antibiotics could be used as extra caution, but probably not necessary.
