Re: bladder cancer
No, I don't think the bone graft could have had anything to do with his bladder cancer...it was probably just an unfortunate coincidence.
Bladder cancer does not typically spread first to the bones, and if a donor had cancer in the bones, it would already have been so advanced that the person would not have been a potential donor.
Secondly, if the grafting was done in a tooth, and there was cancer in the graft material, the first place it would have spread to would have been somewhere in the head/neck...not the bladder.
I'm so sorry to hear that your husband died of this cancer. My heart goes out to you and your family.
