I  I agree that this looks like it may be coming from a suture. It is not uncommon. Typically they will break open and it will be self-limited. Sometimes it requires some additional removal of the suture material and sometimes maybe even anabiotics.  Follow up with your plastic surgeon would be reasonable since you do have implants underneath that incision.  Good luck. 

It looks like this may be a suture abscess, i.e., an infection of the suture that was placed around your areola.  These are typically self limited and should not affect your implants.  You may even have treated it by squeezing the fluid out in which case it will get better and heal.  If not, you may need the offending suture removed.  You may consider a course of oral antibiotics and warm compresses to the area.  

It might be a suture abscess but is hard to say with just a limited image of your breast.  Bes to follow closely with your surgeon.
