Unfortunately, you have not told us your bra size just your cup size. If you are 32 or 34 each 100 cc’s of implant corresponds to 1 cup size change. If you are 36 or 38 each 200 cc’s of implant corresponds to 1 cup size change. From this, you can compute the volume required to achieve your desired goal. However, since you have had pregnancies, you have a loose skin envelope and ptotic breasts. It is possible that the implant will get you the size you want but the skin tone will still be poor. I recommend a new technique called Breast Augmentation with Mini Ultimate Breast LiftTM. Using only a circumareola incision it is possible to reshape your breast tissue creating upper pole fullness, elevate them higher on the chest wall and more medial to increase your cleavage. Through the same incision, implants can be placed. Aligning the areola, breast tissue and implant over the bony prominence of the chest wall maximizes anterior projection with a minimal size implant. Small round textured silicone gel implants placed retro-pectoral look and feel more natural, are more stable, less likely to ripple or have complications needing revision. Implant profile is irrelevant in the retro-pectoral position since the muscle compresses it. Since you do weight lifting, I recommend the smallest implant possible so they do not displace during muscle contracture. Best Wishes,Gary Horndeski, M.D.
