According to a recent article, the increase in early-onset cancer incidence does not consistently indicate an increase in the occurrence of clinically meaningful cancer.
Researchers, including Dr. Patel from Harvard Medical School, examined the trend of early-onset cancer and found that since 1992, the incidence of eight specific cancers (thyroid, anus, kidney, small intestine, colorectum, endometrium, pancreas, and myeloma) in U.S. adults under 50 has doubled, while mortality rates remained stable.
The increase in early-onset cancer incidence does not consistently indicate an increase in the occurrence of clinically meaningful cancer.
Author's summary: Early-onset cancer rise not linked to clinically meaningful occurrence.
