I am 5'2 105lbs was thinking C or D cup for breast augmentation, how many ccs would that be? (Photos)

It is difficult to recommend how many cc's without having a consultation.  We have a Vectra 3D imaging system in office that will show you how you will look with different types of implants and sizes.

The goal of breast augmentation is to create an aesthetic breast with the size, shape, and projection that is desired by the patient. During a breast augmentation consultation, measurements of the breasts are used as a starting point to recommend a breast implant. The decision on size, shape, and position of these implants is based on the patient’s anatomy and the type and size of the implant and patients preferences. 
Based on your pictures you would need a 400-500ml augmentation to achieve a C or D cup. You may also need a lift to compensate for the nipple ptosis. As you consider a cup size, however, it is important to remember that cups do not represent a specific volume. Cup sizes represent a ratio of chest wall or band circumference to breast circumference (projection). So, all other things being the same, a "C" cup on a larger woman would be a "D" cup (or bigger) on a smaller woman.See the link below for more info.
A detailed examination will help delineate the best surgical treatment. In office sizing and digital three-dimensional computer simulations can help guide your implant choices. Consultation with a plastic surgeon certified by the American Board of Plastic Surgery would be the next best step.

Thank you for your question. It is difficult to make a recommendation about size of implants without a proper consultation. Many board certified plastic surgeons offer technology that can do 3D simulation breast imaging so patients can view outcomes not only related to their breasts, but to the entire body as well. I recommend discussing these options with your board certified plastic surgeon, who can individualize your treatment plan.
