Etiology of Young-Onset Colorectal Cancer

About 11% of colon cancers and 18% of rectal cancers occur in adults younger than 50 years. In contrast to the recent population decline in CRC incidence in adults aged 50 and above, CRC incidence has increased in all 5-year age groups between 20 and 49 years. The majority of young-onset CRCs are diagnosed symptomatically with more advanced tumors. Dr. Cao is leading research to discover the genomic landscape of young-onset CRCs and the underlying lifestyle factors that may drive the rising incidence.
