Colon cancer is the most diagnosed in Spain, and it is increasingly diagnosed in younger patients. Now, a global study, the first of its kind, has revealed new details about colon cancer patients under 35 years old.
While there is widely available data on those under age 50, who are considered early-onset cases, the researchers behind the extensive new analysis say there has been a lack of studies on the “very young.”
The new report reveals that disease rates in people under 35 almost doubled between 1990 and 2019, from 21,000 to 41,000, while deaths increased by 25%.
In the United States, rates among people under 50 have increased by 50% in the same period, suggesting faster growth in younger groups.
The study also found that three risk factors were strongly associated with colon cancer: excessive consumption of alcohol, obesity and not consuming enough calcium.
Surprisingly, exercise, smoking, and fiber consumption had little effect on colon cancer risk, even though there are studies linking the three factors with the disease.
The team of researchers, who have published their article in the journal Neoplasia this month, says: “Until now, the disease burden of each early case.
Globally, one in five deaths from colon cancer was related to diets low in calcium, the most significant risk factor.
Alcohol was the second most important risk factor, responsible for 13% of deaths, and obesity accounted for one in 10.
Researchers evaluated colon cancer data from 204 countries and territories. Data was collected from the 2019 Global Burden of Disease Study The Lancetwhich analyzed the risk of chronic diseases and mortality from 369 diseases.
The researchers say that while this data has been analyzed before, a study this large has never focused on in patients under 35 years of age.
The researchers analyzed five dietary risk factors (diet rich in processed meat, diet rich in red meat, diet low in calcium, diet low in fiber and diet low in milk), as well as the alcohol consumptionsmoking, low physical activity and obesity.
In total, global cases of colon cancer in those under 35 years of age increased from 21,874 in 1990 to 41,545 in 2019, doubling in 30 years. Only 61% of cases occurred in men, while 39% occurred in women. This percentage of men with this disease is higher than the average for all groups.
Additionally, the rate of colon cancers in very early stages increased from 0.8 per 100,000 people in 1990 to 1.05 per 100,000 people in 2019.
The researchers did not evaluate risk factors for other age groups, although it is believed that diets rich in red and processed meatslow-fiber diets and smoking are the most significant risk factors in older adults.
Between 1990 and 2019, deaths also increased from 11,445 to 15,486, a 27% jump.
Meanwhile, in 2023, 13,160 Americans between 50 and 64 years They died of colon cancer, suggesting that the disease remains much more common and deadly in older adults.
