Is there a noticeable difference going from 650 to 800 in a silicone implant? (Photos)

Thank you for the question. Keep in mind as you are thinking about your goals that sometimes adjustment of the breast implant pockets (capsule adjustments) may be necessary to achieve the outcome you are looking for.  Also keep in mind that there is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved. My thoughts regarding the potential need for revisionary breast surgery:  I advise patients to carefully consider their degree of concern with the outcome of the initial breast surgery and weigh these concerns against the potential risks/complications associated with the planned revisionary breast surgery.   For example, if the patient is concerned about her breast appearance on a daily or frequent basis, it is likely that revisionary surgery will be helpful when it comes to improving her quality of life.  On the other hand, if the patient's degree of concern seems minor and/or she is  infrequently concerned about the areas of concern, I would recommend against revisionary  breast surgery.

 
Generally speaking, the best online advice I can give to ladies who are considering revisionary breast augmentation surgery is:
1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "up a cup size” or "noticeable difference" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate. 
3. Once you feel you have communicated your goals clearly, allow your chosen plastic surgeon to work with you in determining the best plan to achieve your goals.
I hope this helps. Best wishes. 

I don't think that an additional 150cc on top of the large volume that you have will be worth it.  If you do decide to pursue revision surgery,   I recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with.   Finally, make sure your surgeon is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery (ABPS), a member of the American Society of Plastic Surgery (ASPS), a member of the American Society of Aesthetic Plastic Surgery (ASAPS), and a fellow of the American College of Surgeons (FACS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach TrainedDouble Board-Certified, Double Fellowship-Trained Beverly Hills Plastic Surgeon

Thank you for your pictures and questions. An increase from 650 to 800 cc would be a 23% increase in size, so I would consider this a noticeable change. It will probably be near a cup size in change, but that is a guess. Whether that is worth the surgery is only a question you can answer. Another piece of advice or caution, with 800 cc implants (or 650 cc implants for that matter) over the muscle, these implants are not going to age well with time. You may be happy now, but as time goes by, the weight of an implant that size is going to stretch the breast skin envelope and result in a low set implant and breast position. Most patients with this situation end up needing a revision in a few years with downsizing of the implant and a breast lift (mastopexy) to remove excess skin. In planning, just realize that this is probably in your future at some point.Hope this helps!
