Welcome to Cancer Chat. I can see you have posted a similar post elsewhere on the forum and received a reply from another member.
You can also use the search bar at the top of the page to find other relevant discussions about this, as it is a topic that comes up from time to time.
And of course do discuss this with your husband's doctor when you can, if you have any concerns or questions.
Hopefully you are able to get away, and in the meantime I hope that this forum can be of some help to you.
