Hidden Mutation Rates May Shape Cancer Risk, Study Finds
A study by City of Hope and TGen reveals that healthy individuals exhibit significant variations in organ mutation rates, with some showing mutation levels comparable to cancer patients. These findings suggest that baseline genetic mutation burdens may be a key factor in individual cancer risk.
Why it matters
Understanding these hidden mutation rates could revolutionize cancer prevention strategies and early detection methods by identifying high-risk individuals before tumors develop.
LOS ANGELES AND PHOENIX (Oct. 1, 2026) - A new study by scientists at City of Hope (r) and TGen, part of City of Hope, found surprisingly large differences in the number of mutations present in organs of healthy individuals. Some study participants had a similar number of mutations as is typically found in cancer patients. These results provide an explanation for why some individuals ultimately end up with cancer, opening the door to improved approaches for cancer risk assessment and prevention.
City of Hope is one of the largest and most advanced cancer research and treatment organizations in the country and is ranked among the nation's leading cancer centers by U.S. News & World Report.
