I followed Josh Davis's link http://www.hike4hope.net and watched several of his videos.  His story is amazing as he has had to overcome a diagnosis of stage 3 colon cancer and, the doctors, as usual tried to blame it on something else, while this terrible disease was eating him alive.

I, too, am a cancer survivor (lung cancer, adenocarcinoma), but they caught mine early.  They did watch the tumor grow for a whole year before they decided they better operate, but thank goodness it was a slow growing tumor.  I did not have to do the chemo thing, but I still lost over 70+ lbs which makes me between a size 2 to size 4 and I'm almost 5'11" tall.

I admire Josh for his guts in dealing with this disease.  He looks so thin in his videos.  I hope he beats his cancer; he seems like a fine young man.
