The recent passing of James Van Der Beek at 48 has reignited a crucial conversation: Are we doing enough to catch colorectal cancer early? This disease is becoming a growing threat to younger generations, and it's time to talk about prevention and screening.
Despite a 44% drop in overall cancer deaths among those under 50 since 1990, colorectal cancer has shockingly emerged as the leading cause of cancer death in this age group. It's a stark reminder that we can't afford to be complacent.
When Should You Start Colonoscopy Screening?
Federal guidelines and the American Cancer Society recommend initiating screening at age 45 for individuals with average risk. This involves a colonoscopy every 10 years or a stool test every 1-3 years. But here's where it gets controversial—the U.S. Preventive Services Task Force and the American Cancer Society have debated dropping the recommended age to 40, given the rising rates of colorectal cancer in younger adults.
Colon cancer typically begins with the development of adenomas or polyps, which can later become cancerous. The risk of colorectal cancer for 40-44-year-olds is approximately 21 per 100,000 people, but this risk more than doubles between ages 45 and 49, according to Rebecca Siegel from the American Cancer Society.
The Challenge of Early Screening
The decision to lower the screening age is not without opposition. Critics argue that screening at a younger age may lead to unnecessary procedures and potential harm. However, proponents believe that catching cancer early can save lives, especially with the increasing incidence in younger populations.
The limited number of gastroenterologists and the time it takes to schedule a colonoscopy are also factors to consider. Currently, only about 20% of eligible individuals aged 44-49 are up to date with their screenings, indicating a need for improved access and awareness.
Recognizing the Early Signs
Knowing the early symptoms of colon cancer is vital. James Van Der Beek's initial symptoms included changes in bowel movements, which he noticed at age 46. Research has identified four key indicators that may appear up to two years before a diagnosis:
- Abdominal pain
- Rectal bleeding
- Ongoing diarrhea
- Iron deficiency anemia
Non-invasive stool and blood tests, such as Cologuard and Shield, can be used as initial screening tools, but a colonoscopy is required for further investigation if signs of cancer are detected.
The Cost of Prevention
Colonoscopy remains the gold standard for colorectal cancer detection, but it can be expensive without insurance. The out-of-pocket cost ranges from $1,250 to over $4,000. While non-invasive stool tests like Cologuard can improve accessibility, insurance coverage for these tests typically begins at age 45, unless there are specific risk factors.
Protecting Yourself Against Colon Cancer
The rise in colorectal cancer rates among young people is concerning, and research suggests that lifestyle factors like obesity, lack of physical activity, gut microbiome changes, and diets high in ultra-processed foods may be significant contributors. Antibiotic use and specific gut bacteria have also been implicated in some studies.
Dr. Andrew Chan emphasizes that while screening is crucial, adopting a healthier diet and increasing physical activity can significantly reduce the risk of colorectal cancer. These lifestyle changes may offer broader health benefits beyond cancer prevention.
So, should you get screened earlier? If you have a family or personal history of colorectal cancer or polyps, the answer is yes. But for those with average risk, the decision is more nuanced. As we grapple with the increasing incidence of colorectal cancer in younger adults, it's essential to stay informed and engage in open discussions with healthcare professionals about the best course of action for your individual circumstances.
