Change of implants - what will the difference from 470cc HP to 620cc be like? (Photo)

If your surgeon says don't do them, then don't. Larger implants will stretch and thin your own tissue even more and you may not support the weight. You may bottom out or sag. Plus, they will be heavy on your neck and shoulders.

A 620 cc implant may be too large for you unfortunately. Although the amount of increase in volume is the same as your last surgery, the strain on your thin breast skin is likely too much for your breast to handle and you run the risk of multiple cosmetic breast issues long term that could be very difficult to fix. It appears that you have a nice cosmetic result and my recommendation would be to keep your current size

Dear Helpful182370,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals
