Dear Esmeralda,
Thank you for your question and photo. How big are you desiring to be? Size of the implant is more related to chest dimensions than cc's. The base width of your breast (planned, not actual) is important in determining size. Be careful of a size too big for your body to support. Think long term on this. How do you want your breasts to look 5-10 years down the road? Very large saline implants under the muscle will not necessarily look good long term. The muscle and gravity tends to push them down and to the side (arm pit) with time as there is nothing other than your skin holding them in place. You do not want to have very large pendulous breasts down the road, but flattering and perky. Make sure you are consulting by a plastic surgeon who is board certified by the American Board of Plastic Surgery. Being a D size cup, I think would be fine for you, but going more than this may cause problems down the road. Also, using textured silicone implants can help keep the implant in place longer term than a smooth implant. The following is an example of a girl who went to a size D from a B with silicone textured implants with the proper base width implant selection. Her implants for example were 450cc. She was about your size and weight.
Best Wishes,
Pablo Prichard, MD
