Random mutations that lead to cancer are basically “bad luck.”
Cancer can be caused by tobacco smoke or by an inherited trait, but new research finds that most of the mutations that lead to cancer crop up naturally.
The authors of the study published Thursday poked a hornet’s nest by suggesting that many cancers are unavoidable.
The provocative findings by Bert Vogelstein and Cristian Tomasetti at the Johns Hopkins Kimmel Cancer Center, have stirred up a heated scientific debate that started two years ago, when they published a report along similar lines.
Back then, critics said they were undercutting important messages about cancer prevention. So when these scientists had new results to report, Vogelstein addressed that concern head-on.
“We all agree that 40 percent of cancers are preventable,” he said at a news conference. “The question is, what about the other cancers that aren’t known to be preventable?”
