My sister recently had 2 surgeries done privately (cosmetic but reconstructive) and could have chose 1 surgeon to do them both but chose 2 different ones. Each one wanted to know - insisted actually - who was / is doing her other surgery. So these surgeons attend the same conferences / professional networks etc and now she is nervous about a follow up next week because she thinks they will have discussed her case amongst themselves. Do surgeons do this? I think yes they probably do but have told her they don't!
