Curing Cancer

I just got back from a wonderful trip to a beautiful country: Luxembourg. I highly recommend it. However, we left before I could point to an incredibly exciting development in medical science: a potential cure for cancer. The particular cancer in question is leukemia, although the potential cure may be applicable to others. Basically, they reprogrammed some of a patient's white blood cells to hunt down any and all cancer cells. They tested it with three people with advanced-stage leukemia: a couple weeks later, they experienced the equivalent of a horrible case of the flu -- which meant it was working. A year later, two of the patients have no sign of cancer, and the other still has it, but is no longer dying from it. Amazing!
