The cup size measure has inherent variability. Tissue density will always play a big role in the number of grams removed. Going too small can sacrifice the shape of the breasts. After breast reduction, your belly, legs, and arms will appear bigger than before the surgery. The nipple has to have a blood supply to survive from the underlying tissue. You can always tighten the skin later if not aesthetically pleasing, and breast mass will decrease with time. In general, scarring is a product of genetics. For keloid formers, there is not a way to prevent keloids. In general, the longer the scar or the greater the number of scars, the greater the chance for keloids. I always minimize the scars to minimize the likelihood of poor scars. The keloids may require multiple modalities to achieve the best results. Laser may help to some extent with some types of scarring issues. As an author of Scars and Scar Revision in Reoperative Plastic and Reconstructive Surgery, I am well versed in the potential treatment options. One treatment may be helpful for one patient while another treatment may help another patient.There is no one best therapy for scars. Silicone sheets, Mederma, and Bicorneum are reasonable and popular options. I recommend that the scar therapy begin after the scars have healed and there are no open areas, which usually takes 4 - 6 weeks. Consult with a board certified PS who performs hundreds of breast procedures each year to discuss your candidacy for the BR, the pros and cons of BR, and the most appropriate time for you to have the surgery.
