WebHorvath also analyzed nearly 6,000 samples from 20 different cancers and found that cancer greatly affected DNA methylation age. However, in most cancers the age acceleration didn’t reflect the tumor grade and stage. The rate of ticking of the biological clock, as measured by the rates of change in DNA methylation, wasn’t constant.
