This is Scientific American’s 60-Second Science. I’m Steve Mirsky. Got a minute?
“Only 10 percent of people die from primary tumors. The real problem is when it spreads around the body. The problem of metastases.” Arizona State University’s Paul Davies, speaking at the Penn Club in New York. “I don’t think we need to cure cancer. In fact, I don’t really think of cancer as a disease as much as an alternative form of living matter. We don’t need to cure it; we just need to manage it for long enough that people die of something else.”
The cosmologist was asked to study cancer by the National Cancer Institute. “When cancer cells spread around the body, this is a physics problem. These cells are microscopic1 bodies being swept along in this raging torrent2. They wriggle3 around, they latch4 on to surfaces, they drill their way through. This is the sort of language that physicists5 and engineers can understand. Cancer research is dominated by genetics and biochemistry. That’s why we have the therapies, genetic6 and chemotherapy, as the main approaches. I think that we can open up a whole new frontier just by thinking about the problem in a totally different way.”
