clones

HBO had a "First Look" at the movie, "The Island." It's some sort of directors commentary/extended preview of the movie. "The Island" is apparently about a place on earth where some folks have a clone of themselves living, in case they need a spare organ/body part. It's a bit of an action flick and looks like a little too much running for me to enjoy—no matter how lovely Ms. Johansson is.

However, the purpose of me bringing this to my blog, was because of what the director said the core concept of the movie is:
"If we could, would we have a clone?"

...If I had a clone, would my clone also get cancer? Would the cancer have come back three times in my clone? How much does nuture (environment and lifestyle) *really* effect the development of a cancer (excluding the obvious smoker-lung relationship)?

Would a transplant from my clone be considered autologous or allegneic?
