That's terribly bad news ailsa, I am so sorry to hear that.  Can I suggest that you call the nurses here on the forum.  They are really easy to talk to and will be able to give you a lot of information.  They have a freefone number which is a shown at the bottom of this page.  They are contactable Monday to Friday during office hours.

Wishing you and your boyfriend all the very best and hope he responds well to treatment x
