Rise in young colon and rectal cancers
The article discusses an increase in early-stage colon and rectal cancer rates among young people under the age of 50, despite a decline in older age groups. International studies have shown that this type of cancer has risen in 27 countries, with a particular increase among youth. The changes are attributed to factors such as the rising prevalence of obesity, dietary pattern shifts, deterioration of the gut microbiome, as well as prolonged exposure to environmental and dietary factors over decades. Evidence suggests that this condition may originate in childhood, involving environmental and biological changes such as the interaction of the bacterium Escherichia coli (Colibactin) with colon cells, leading to early mutations that make cells more susceptible to cancerous transformation. Experts recommend early screening at age 45 for individuals with moderate risk, and emphasize the importance of adopting a healthy lifestyle that includes maintaining a healthy weight, engaging in physical activity, consuming fiber-rich foods, and reducing intake of processed meats and alcohol to lower risks. It is also noted that the causes are still not definitively understood, but it is believed that a combination of genetic and environmental factors contributes to the rising incidence.
