How much will breast size increase with either a 210 or 240 cc implant? (photo)

Based on the picture which appears to be about an A/B cup with some deflation of the breast/skin envelope, one would expect to be a moderate B after a 240 implant. The chest is moderately wide and there is some loose skin, so 240 is a conservative augmentation.

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  Based on
your photographs, the best shape and contour could be achieved with an implant
and a breast lift.  210-240cc is likely a good size range for you.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.

Thank you for the question.There is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved. For example, I do not think that the generalizations of "200 cc equates to 1 cup" hold any validity or are helpful in any specific or practical way.  In my practice, I ask patients not to communicate their goals, or evaluate the outcome of the procedure performed, based on cup size references. Generally speaking, patients undergoing the combination breast augmentation/lifting surgery should understand that there are limits as to how large of an outcome can be achieved  and how large of a breast imlpant can be utilized safely), given that breast lifting surgery does involve breast skin removal. On the one hand, breast augmentation surgery is expanding the breast skin “envelope” while breast lifting is (by definition) tightening up the breast skin envelope. These 2 forces are counteracting each other. 
Therefore, it becomes important to remove the appropriate amount of breast skin and to use the appropriate size/profile of breast implants to balance these 2 forces appropriately and to allow for achievement of the patient's goals while minimizing risks of complications. 
In my practice the tailor tacking technique is an important part of the mastopexy and mastopexy/augmentation procedure. It involves TEMPORARY  closure of the skin (for example with temporary skin staples)  to double check the amount of skin that is to be excised during the procedure. This maneuver is done to ensure that enough skin, but not too much, is removed. On the one hand, it is important that enough skin be removed to achieve the aesthetic breast lifting results the patient is looking for; on the other hand, is important not to move too much skin creating tension upon closure and potential wide scars.
Also, generally speaking, the best online advice I can give to ladies who are considering breast augmentation/lifting surgery (regarding breast implant size/profile selection) 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. Again, have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining which operation and/or 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 "C or D cup" 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. The use of computer imaging may be very helpful during this communication phase.
3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery. The use of temporary intraoperative sizers and the tailor tacking technique with the patient in the upright position makes selection of the best breast implant size/profile relatively easy.
I hope this helps.

Since implant volumes do not correlate well with bras, it is hard to tell .You can try a baggy test with the bra that you want to fill to get an idea.

The general rule of thumb is that for each 150-175cc of implant your breast will increase by one cup size. so 210-240cc will increase you by about 1.5 cups. Best,~Dr. Sieber

That is a very difficult answer to give accurately. The picture that you have shared puts you at what is conventionally considered an A/B. Again that depends where you go shopping for bras!!! Of note your breast are deflated and therefore when chosing an implant we take that into consideration. The implant that you chose will have to contribute the majority of the volume since you do not have a lot of breast tissue. I feel that you will end up with a fuller breast nevertheless, still remain in the B range. It will definitely improve the contour. Please be mindful that 240cc is not taking into consideration the different profiles of implants. Therefore, a 240ish cc implant can look different if it is a high profile versus moderate profile. I hope that helps. Good Luck.

Hello,
I think looking at your picture that you are size A cup now and after 210 to 240 cc implant you should look like a full B cup.
Wish you all the best.
