The risks are very small, CC used to be one of the most common problems after a BA, they will never eliminate it but the risks are so much lower now than they were years ago due to the constant improvements to implants and the types of filling used, your risks are small but the problem with CC nowadays is that it can take months to develop to the point where it’s suspected and diagnosed whereas with the saline types symptoms would be seen very quickly, i would have real concerns about only being covered for CC for 12 months, do lots of research before you head into theatre if your finding it’s a major concern for you then at least your decision is an educated one xxx
