New cancer research challenges the 'bad luck' hypothesis

New research has found that environmental exposures, lifestyle choices and other factors that could be changed or avoided account for between 70 percent and 90 percent of the gene mutations that make cancerous tumors progress, leaving “intrinsic factors” to account for the minority of malignant tumors.

Among cancer researchers, 2015 may be remembered as the year that the role of bad luck in cancer’s origins became a key object of debate.
