I think that when making the decision to go ahead with any surgery you have to weigh up what the benefits will be for you,in any surgical procedure there are risks,but do the benefits of this procedure out weigh the risks for you,I researched for years,I really wish I had gone ahead years ago,having a BA has made such a difference to my life,and yes,before my operation I did ask myself the same questions that you have,its is entirely your decision,but for me,it was the best decision I ever made.
Also consider that technology and procedures are advancing all the time,hundred of women make the decision to change the way they look through cosmetic procedures,and they are perfectly fine,I am sure you will come to a decision that you feel is right for you,speak to some of the girls,they will reassure you based on personal experiences, that the operation itself is not a problem,however you are the only one that can come to terms with your fears and decide is it worth it for you,please feel free to message me if you want to chat,good luck honey.xxx
