Hello, I have been reading your website off and on for 5 months, since the midst of my husband's chemo/ radiation treatment for 
HPV+ tonsillar cancer.  It was a tough road, but he was progressing beautifully.   The last treatment was December, 2012.   I was mentally beginning the party planning to celebrate and thank all of our relatives and friends who helped us through it--when the 3-month PET/non-contrast CT came back with worrisome spots on lungs.  A followup biopsy has confirmed metastasis to the hilar lymph node of lungs.  One small spot, less than a centimeter, (even too small for trial participation) but "terrible" news. (to quote our rad onc).  We have two very conflicting approaches from two different centers here in the Baltimore/DC area:  
[1. Wait 8-10 weeks and do a CT with contrast to see how it's behaving.  If growing, begin chemo
2.] Don't screw around with it and start chemo now.
I have looked and looked and perhaps it's my unfamiliarity with the website, but I do not see similar situation.  I know this is not a common occurrence, but if there is any insight out there, I would love to hear it.  Thank you so much.
Sincerely,
Mary
