Research demonstrates that cells with cancer-associated mutations overtake human tissue with age

December 13, 2021

It’s worth noting, in light of recently published research, that a majority of people won’t be diagnosed with cancer in their lifetimes. According to the National Cancer Institute, about 40% of people will, which means 60% won’t.

These percentages are worth remembering because research conducted by University of Colorado Cancer Center Deputy Director James DeGregori, PhD, a professor of biochemistry and molecular genetics, and Edward J. Evans, PhD, a postdoctoral fellow in the Department of Biochemistry and Molecular Genetics, found that most cancer-free individuals over age 60 carry at least 100 billion cells harboring at least one oncogenic, or tumor-causing, mutation.
