How many cc is suggested for a silicone high profile implant?

Generally speaking about 200 cc of breast implant will increase the breast one cup size.However it is very important that you have an in person consultation and examination by an excellent board certified plastic surgeon.  The surgeon will measure your breast and chest and also use a breast implant sizing system.  During the breast implant sizing system evaluation implants will be placed into your sports bra and you will be able to see how the shape and size of each various implant looks on your body.High profile breast implants are typically use for patients with very narrow chests and small frame.  However moderate profile plus breast implants will give you more cleavage and more fullness on the side of your breasts.

Thank you for the question. There is no accurate correlation between size of breast implant and cup size achieved.
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 "full C 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.

The answer varies from patient to patient. Your best bet is to visit you your plastic surgeon and size. Your starting size, your base width and your frame all factor into implant size choice.
