Oh, Paul!
I am so very sorry to hear of such a horrible experience!  You must be wondering what the f**k is going on!  It makes not sense!  Do they have any idea why this is happening to you?  Was your cancer 
HPV+?
I will be thinking of you and hoping for the best as you enter treatment yet again.  I hope you have a strong support system in place.  I cannot imagine how one would handle all of those recurrences.  
Thank you for taking to the time to think of me and wish me luck.  You must be a fighter to have made it this far.  I look forward to seeing you back here as you are able.
With great care,
Kerri
