Colorectal Cancer Strikes Younger Adults More Often, Now Leading Cause of Cancer Deaths Under 50
Colorectal cancer is striking younger adults more frequently, with incidence rates rising by about 2% annually since the mid-1990s. This alarming trend has made it the leading cause of cancer-related death in US men under 50 and is set to top the list for women under 50 by 2030. Early detection is crucial, and understanding red-flag symptoms is key.
Dr. Kimmie Ng, a gastrointestinal oncologist at Dana-Farber Cancer Institute, has been treating young adults with colorectal cancer for two decades. She warns that environmental factors like obesity, sedentary behavior, and diets high in red meat and processed foods may contribute to this rise. The US Preventive Services Task Force lowered the screening age from 50 to 45 in 2021, reflecting the increased risk in younger adults.
The causes of early-onset colorectal cancer are multifactorial. While most cases aren't explained by heritable factors, young patients have a higher chance of being diagnosed with hereditary syndromes like Lynch syndrome or familial adenomatous polyposis. The development of risk factors is linked to a combination of genetic predispositions, lifestyle factors, and possibly environmental influences.
Colorectal cancer in younger adults is a growing concern. Understanding and addressing modifiable risk factors, such as diet and obesity, and being aware of red-flag symptoms can help in early detection. The medical community continues to study and address this worrying trend to improve outcomes for young patients.
