Cancer Risk: Genetic, Behavior or Just Bad Luck? Auremar/PhotoSpin

Offit emphasized the importance of continuing to stress important public health awareness messages and stated that approximately half of all cancer deaths could be avoided.

Offit said, “Although most cancer is likely due to random events (affecting DNA replication) at the cellular level, at the population level, the most powerful interventions to decrease the burden of cancer are to stop smoking, know your family history and aim for ideal weight.”

Since so many cancer cases are the result of random genetic mistakes that cannot be predicted or prevented, Tomasetti and Vogelstein believe their research points to a need to develop better tests for early detection of cancer so it can be more effectively treated.
