Lump underneath areola, after breast augmentation.

First, I would agree that you should be seen by your surgeon.  While not all Plastic Surgeons see their patients at the first post-operative visit, by 8 weeks you really should have been seen by the doctor and not just their nurse.  
I would personally ask to be seen by your treating physician and ask them this question.  This lump may be benign but no lumps in the breast should simply be ignored.
I hope that helps!

Thanks for this question. I think you should see your doctor. They may need you to get an ultrasound or other similar test. Best wishes, Dr. Aldo
