Why more young adults are being diagnosed with colon cancer: Oncologist Dr Ravi K Gupta shares risk factors and symptoms

Colorectal cancer diagnoses are rising in adults under 55, now accounting for nearly 1 in 5 new cases.

Dr. Ravi K Gupta cites changes in the gut microbiome, including low fiber, ultra-processed foods, and antibiotics, as risk factors.

High intake of ultra-processed foods and sugary drinks is linked to increased colorectal cancer risk, especially in men.

Poor metabolic health, such as obesity and type 2 diabetes, also raises risk of early-onset colorectal cancer.
