A good friend and coworker was diagnosed with stage 4 esophageal cancer (spread to intestines, pancreas, etc) before diagnosis about 3 weeks ago. He just ran the Boston marathon this year and is in excellent shape. He doesn't eat red meat (has high cholesterol), doesn't smoke, dip, etc. He has two young boys (7 & 9 I think). I've been really having a hard to understanding/accepting this. Can only imagine how much harder it is being your little sis.
