White Head Looking Thing on Areola? (photo)

I agree with the answers already provided.  This small raised area does not likely represent anything of concern.  It is likely related to the sutures beneath the skin surface.  It may unroof itself with a tiny bit of pus-like fluid found beneath it, but it does not typically progress beyond that minor irritation although it may cause a small raw site that will heal over with time.  Your surgeon can confirm this in follow up.

The white dot represents a small pustule and is commonly seen around incisions within days to 1-2 weeks after surgery.  They represent a small superficial infection typically at a hair follicle or sebaceous gland.  Local wound care will typically resolve this with topical antibiotics. No other treatment is warranted and no long term consequences occur.

This is related to a plugged oil gland on your breast.  Stop putting bacitracin or other oil based ointments on your breast.
