Study: Up to 90 percent of cancers not ‘bad luck,’ but due to lifestyle choices, environment

Scientists have long agreed that a person’s risk of getting cancer comes down to a mix of genes, lifestyle, environment thrown in with some measure of chance. But the relative importance of each factor has never been settled.

In early January, a team of researchers from Johns Hopkins Medicine caused a stir when they published a study in the journal Science detailing their “bad luck” hypothesis for how normal cells turn bad. Their work involved trying to figure out why tissue in certain parts of our bodies are more vulnerable to developing cancer than others and they concluded it had to do with how many times they divide — a process that occurs somewhat at random.
