Earlier this month, the actor James Van Der Beek, known for his role in Dawson’s Creek, passed away after a two-year fight against bowel cancer at the age of 48. This age bracket has often been associated with older adults, making his diagnosis particularly striking.
The young star is not alone, as other younger public figures, like British journalist Dame Deborah James, who lost her battle at just 40, have also succumbed to this disease after being diagnosed at 35.
There’s a growing concern—cases of early-onset bowel cancer, especially among those under 50, are increasing significantly worldwide. In the UK, individuals in this age category today face about a 50% higher likelihood of developing bowel cancer compared to their counterparts three decades ago.
Researchers, including Professor Sarah Berry from King’s College London, are actively investigating this alarming trend. She is spearheading a substantial study called Prospect, funded with £20 million, aimed at uncovering why this spike is occurring.
In the coming months, Professor Berry’s team intends to recruit thousands of healthy young Brits for the study. They plan to track the participants’ dietary habits, lifestyle choices, and genetic backgrounds over several years. The aim is to identify common risk factors for those developing bowel cancer before 50.
There’s a glimmer of hope that these insights could lead to preventive measures against early-onset bowel cancer. However, Professor Berry emphasizes that individuals shouldn’t wait for study results to start making lifestyle changes that could lower their risk, as there are numerous already identified factors that people can act on today.
“While we don’t yet know what exactly is driving this increase in young people getting bowel cancer, we are aware of habits that elevate the risk later in life,” she stated.
Remarkably, she notes that about 50 to 60 percent of bowel cancer cases could potentially be prevented. There are actionable changes people can make now to reduce their risk.
Processed Meat
One significant culprit linked to bowel cancer is the regular consumption of processed meats, according to Professor Berry. Items like bacon, ham, sausages, and salami are classified as carcinogens by the World Health Organization. Research indicates that eating just 50 grams of processed meat daily can elevate the risk of bowel cancer by around 18% due to chemicals like nitrates utilized in preserving these products.
“We know that a diet high in processed meat increases bowel cancer risk,” she added, highlighting that this is a key area for dietary change.
Sugary Drinks
Another identified risk factor is sugary drinks, frequently consumed by younger individuals. A striking report showed that one in eight teenagers in the UK drinks sugary fizzy beverages daily. A substantial study in the U.S. found women who drank two sugary beverages a day were twice as likely to develop early-stage bowel cancer compared to those who consumed much less.
“Sugar-sweetened drinks are a significant risk factor for bowel cancer,” Professor Berry affirmed, noting that consumption is indeed rising among the youth.
Ultra-Processed Food
Moreover, artificial ingredients typically found in ultra-processed foods could also be driving the increase in bowel cancer rates. These materials, which include emulsifiers, flavorings, and stabilizers, aren’t found in regular kitchens and make up around 40% of the British diet. Concerning findings from a study indicated that those consuming a diet rich in ultra-processed foods had a higher likelihood of developing bowel polyps, which could become cancerous.
“There is some evidence suggesting that additives in these foods could lead to inflammation in the bowel,” Professor Berry noted, although further study is necessary to solidify this connection.
Not Eating Enough Fibre
A common nutritional shortfall—fiber—could also contribute to this uptick in bowel cancer cases. Data reveals that a significant portion of Britons aren’t getting sufficient fiber. The NHS suggests aiming for about 30 grams daily, roughly equivalent to five portions of fruits and vegetables.
Interestingly, increasing fiber intake appears to correlate with a lower risk of bowel cancer, with studies suggesting that adding just 10 grams more can decrease risk by 10%. The exact reason remains unclear, but some theorize it could protect the gut from potential cancers.
Drinking Alcohol Without Meals
Consuming alcohol on an empty stomach might also heighten the risk of bowel cancer, Professor Berry contends. Defined benchmarks suggest that exceeding 14 units weekly correlates with a 25% higher cancer risk. But recent research hints that drinking without food could further elevate this danger.
“Food appears to absorb alcohol, possibly lessening harm to the gut lining,” she described, adding that consuming alcohol during meals may be less damaging overall.
A Common Gut Problem
Another significant factor could be inflammatory bowel disease (IBD). This condition affects around half a million Britons and is linked to a staggering 600% increase in bowel cancer risk. IBD encompasses diseases like Crohn’s and ulcerative colitis, which lead to severe inflammation and symptoms ranging from debilitating pain to diarrhea.
While the exact cause remains a mystery, it’s speculated that an overactive immune response is at play. Studies suggest diets high in ultra-processed foods might elevate the risk of developing IBD, which in turn may cause harmful changes in the gut capable of leading to cancer.
Sitting Down for Too Long
Lastly, a sedentary lifestyle may also contribute to the risk. Research indicates that individuals who spend considerable time sitting—like those with desk jobs—are at a greater risk for developing bowel cancer. Recent studies suggested that those watching five or more hours of television daily were 30% more likely to develop the disease compared to those watching very little.
As Professor Berry highlights, the connection between long periods of inactivity and bowel cancer is emerging, warranting further investigation.
