I am sorry for your father. We just lost my neighbor and my wife's best friend last week to colon cancer. It hit us pretty hard. Everyone I had ever lost was sudden, here one minute, gone the next, from a heart attack, car accident, or such. Watching the slow, lingering, wasting away to nothing death was one of the hardest things I have ever went through. Cancer sucks, I hope this treatment proves beneficial so others do not have to go through what she did.
