Thank you both for your answers. I feel less ...guilty.

Maybe I will be more careful though. During the next appointment I intended to ask about the risk of relapse induced by the upcoming surgery. (I had asked the question in another thread)
He may not have even thought about that and it could add to his stress.
Or maybe he has and he doesn't dare ask the question.

I will definitely have a conversation with him. You are right Neil, it's up to him to decide.

Thank you so much Data! I wish you all the best too.
