Something real is happening to younger bodies, and brushing it off as better scanning is reckless. Obesity, ultraprocessed diets, alcohol, pollutants and a disrupted gut microbiome have stacked risk onto generations from childhood onward, and tumors in young patients look biologically different. Deaths are climbing too, so waiting for perfect proof means losing people in their prime.
An epidemic of testing is being mistaken for an epidemic of disease. More imaging, more scopes, more checks and lower thresholds for calling something cancer will always produce more diagnoses, yet deaths from most of these cancers have stayed flat or fallen. Hunting for mysterious new exposures drains money and attention while overdiagnosis runs the risk of turning healthy young adults into lifelong patients.
