One of my relative is surgeon and he does not go into the surgery of the people he knows -friends family etc- He said most of his surgeon friends like that too. When someone they are related needs a surgery they trust some other surgeon they know.
Yes because personal emotions can affect the process of a surgery a lot, especially if it's a critical one. So it's better if your surgeon is someone completely unrelated to you.
