Colorectal cancer deaths rise as younger adults face advanced diagnoses

A concerning trend is emerging in the fight against cancer: while mortality rates for most cancers have been declining, deaths from colorectal cancer have been steadily increasing since 2005, rising by 1% each year. This makes colorectal cancer the third-most diagnosed cancer in the United States, according to the Cancer Research Institute.

A Shift in Diagnosis

Doctors at Marshfield Clinic in Weston, Wisconsin, are observing a particularly troubling pattern. They are seeing more young adults – those under 50 years old – diagnosed with colorectal cancer, and a significant portion, two-thirds, are presenting with advanced stages of the disease. This late-stage diagnosis contributes to increased mortality and morbidity.

Did You Know? Since 2005, colorectal cancer is the only major cancer type in the U.S. where death rates have increased annually.

Why the Change?

One key factor appears to be a lack of awareness and screening. Many younger adults don’t believe they are at risk for colorectal cancer and therefore forgo recommended screenings. Symptoms, such as lingering abdominal pain, unexpected weight loss, or bloody stools, are often ignored, potentially delaying diagnosis and treatment.

Family history also plays a crucial role. Colon cancer can be hereditary, meaning individuals with a family history of the disease have a higher risk. Dr. Adedayo Onitilo, chief of oncology services at Marshfield Clinic, emphasizes the importance of open communication within families. “It’s very important that people know their family history and it’s also very important not to hide it. There is no taboo in having cancer. It’s good to share it,” he stated.

Expert Insight: The increasing incidence of late-stage diagnoses in younger adults suggests a critical need for increased awareness and potentially a reevaluation of current screening guidelines. The reluctance to discuss symptoms and family history creates a significant barrier to early detection.

Understanding the Causes and Treatments

While the exact cause of colorectal cancer remains unknown, dietary factors are suspected to contribute to the rise in cases. Dr. Onitilo points to “Western diets” and sugar-sweetened beverages as potential culprits.

Currently, treatments like chemotherapy and immunotherapy are available. These treatments can eliminate the disease in stage-3 cases and extend life expectancy for those with stage-4 cancer.

Frequently Asked Questions

Yes, colon cancer can be hereditary, and those with a family history of the disease have a higher chance of getting it themselves.

What is the current recommended screening age?

The recommended screening age is 45, although doctors at Marshfield Clinic are considering whether that age should be lowered.
