Researchers are not exactly sure why there has been such an increase, but say it could be linked to a growing rate of obesity, poor diets and a lack of exercise.

Cancer is rising in younger adults. Faster biological aging may help explain why

Cancer rates are rising in adults under 55, and new research suggests accelerated biological aging may be one piece of the puzzle. Scientists found that people from more recent generations tended to have bodies that appeared biologically older than those of earlier generations at the same chronological age. Greater biological age acceleration was linked to a higher risk of early onset cancers, with specific patterns seen for lung, gastrointestinal, uterine and colorectal cancers.
