joe1619.....last Sundays 60min on CBS talked about a dr doing surgery at UPMC (pittsburgh pa) on a man that had esophegal cancer.
I dont know if you can access the program still at cbs.com. I would post the URL but I dont know if I am permitted to do that.
The show was about how they are growing replacement parts for our bodies ears....bladders.....heart valves......and they mentioned surgery done on this man for cancer of the esophegus. The dr I went to did his surgery. I dont remember the exact details but they lined his esophegus with material made from pig bladder. They are doing some wonderful things.
