#Early Detection

The alarming rise of colorectal cancer among younger adults highlights the importance of vigilance and proactive health measures. Though traditionally associated with older populations, colorectal cancer is increasingly affecting individuals under 50, according to recent observations by the Mayo Clinic. The term “colorectal cancer” encompasses both colon cancer, which affects the large intestine, and rectal cancer, which begins in the rectum. Over the past two decades, an uptick in cases among the younger demographic has become apparent, with rectal cancer exhibiting a particularly pronounced increase.

Colon cancer, also known as colorectal cancer, has become increasingly significant worldwide and in Thailand, reflecting global trends and attracting healthcare attention. The American Cancer Society’s recent estimates reveal approximately 107,320 new colon cancer cases in the U.S. in 2025, underscoring a growing need for prevention and early detection measures. While overall colon cancer rates in older adults have decreased annually, worrying trends show a 2.4% annual increase among those under 55 from 2012 to 2021, prompting heightened awareness and strategy adaptation in fighting this disease.
