Is it a 600-650 cc silicone implant too big for someone 5'1 and 140 pounds?

Thank you for the question. Despite your good description of your body type, online consultants will not be of specific enough help to you. Generally speaking, the best online advice I can give to ladies who are considering breast augmentation 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're 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 “C or D cup” etc means different things to different people and therefore prove unhelpful. Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. The use of computer imaging technology may also be very helpful during this communication process.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.I hope this (and the attached link) help.

It is not unreasonable to place 600-650cc breast implants in someone with your body  dimensions.   However, you must take into consideration chest size, tissue elasticity, breast measurements as well as aesthetic look you are trying to achieve.  You must also pick the correct type of implant to help you achieve this result.  In some patients this sized implant is not possible while in others its not an issue.  It is best to consult with an experienced board certified plastic surgeon in your area.Dr. Cambeiro SurgiSpa Plastic SurgeryHenderson, NV
