I had my original breast aug on 4/15/11 with 400 cc silicone implants to fix tubular breasts. Three months ago I was told I had grade 3 capsular contracture in the left breast and had my revision surgery 1/17/11. I was told a new implant would be used if needed. My surgeon said he removed the implant along with a lot of scar tissue but there was some under the ribs which he left in place and then replaced the original implant. Is this dangerous? And what are the chances of this reoccurring?
