Colorectal cancer diagnoses in adults under 50 are rising, prompting research into the causes. While increased screening since guidelines lowered the recommended age to 45 explains some of the rise in early-stage diagnoses, it doesn't account for the overall increase, including late-stage cancers, observed since the mid-1990s. Studies published in JAMA show a significant increase in screening rates among 45-49 year olds, correlating with a surge in early-stage diagnoses. However, experts emphasize the need for further research into underlying factors like diet and environment and highlight the importance of knowing warning signs and seeking medical attention for persistent symptoms.
