Xeloda

I take xeloda 1 week on and 1 week off.  I started taking it this time in December 2013.  My hands are red and peeling and my feet are red and hard and cracked and I occasionally I get blisters on my heels.  My tumor marker numbers are still going down.  Last couple times it was 21.3, 20.3 then 19.0.   I feel great other than my feet and hand problems. I have a PET scan in a couple weeks, and hope to hear good news.  My dr says the numbers can change from day to day a little bit.  I had blood work once, and it was over 70 (not on the xeloda), then they re tested me a week later, and it was a little different.  I think it was 72.   I have been told uner 37 is good.  Although, my dr said mine isnt reliable to say if I do or dont have cancer still.   My friend who is cancer free now, for 7 years, just got tested, and her number is 16.8.  I guess that is normal.  Mine have been down to 16 at the lowest, and 105 at the highest, but not recently.
