Colorectal cancer genetically different in older and younger patients

While the overall rate of colorectal cancer (CRC) is declining, CRC specifically among young patients is increasing. Previous studies have shown that CRC in patients younger than 50 years old tends to be more aggressive than CRC in older patients. A new study offers early evidence of genetic differences between CRC in young and old patients, possibly pointing toward different treatments and strategies in combating the young form of the disease.
