How much is breast implant from a 36b to 38D?

Breast augmentation costs differently in different parts of the country. Beware of the "bargain basement" augmentations as these may not be offered by surgeons boarded by The American Board of Plastic Surgery, the only official board to certify plastic surgeons. The price is also determined by the type of implants used (saline vs silicone) and/or if a lift needs to be performed. Only with an exam in person can those decisions be made. In my office in Nashville, breast augmentation runs around $5000-6000. Good Luck

Cost of surgery will vary from one practice to another and from one geographic area to another. You will find the information listed on this site helpful in this regard. You will also find cost of surgery listed on some individual plastic surgeon's websites as well.
In regards to come out the planned procedures, more important than costs of the procedures will be  careful selection of your plastic surgeon. I would suggest starting with the American Society of Plastic Surgery and/or the Aesthetic Society of Plastic Surgery to obtain a list of well experienced board-certified plastic surgeons.
Then, I would suggest you visit a few surgeons whose practices concentrate on aesthetic surgery. Ask to see lots of examples of their work and preferably speak/see patients who have had similar procedures done.
You will find, while doing your due diligence, that there are many different “specialties” who will offer their services to you; again, I strongly recommend you concentrate on surgeons certified by the American Board of Plastic Surgery.
Again, I would also suggest that you do not base your selection of plastic surgeon primarily on costs of surgery; keep in mind that revisionary surgery may be more costly in many ways.  I hope this helps.
