An update, what creams are used when having radiotherapy?

That is good news, @GavinCh.  You sound like an amazing men and Karen is so lucky to have you as her support.  Some partners are the 'head in the sand' type but you have been and continue to be proactive through a difficult time.
It was a good idea for you to join BCNA as it gives you a place to learn and to just talk to others who understand.  We all hope Karen will find her way here over time.
You are both in my thoughts.
