Back story : Husband had Cancer several years ago ,was treated got the all clear (thank goodness)!,However seems to be convinced its come back in another part of the body!.Goes to see the Doctor a lot for reassurance !.AIBU to think he shouldnt keep doing this?.Part of me realises that he is worried and with good reason obviously!.But also worried Doctor is going to be fed up with this ?.Good relationship most of the time but worries endlessly and gets annoyed if I say this .How do other people who have been in this position cope?.All I see is people doing Marathons ,Long cycle rides etc !
