Colorectal cancer risks rise among younger generations

Colorectal cancer cases are rising sharply among younger generations, including Gen Z and millennials. A study published in the British Journal of Surgery (BJS) indicates that individuals born in 1990 face double the risk of colorectal cancer compared to those born in 1950.

Research suggests that the consumption of ultra-processed foods (UPF) is a significant contributing factor. These industrially processed foods can promote the formation of precancerous growths in the large intestine. Key dietary triggers identified include processed meats—such as sausages, bacon, and nuggets—which often contain preservatives like nitrites that can cause inflammation and DNA damage. Additionally, sugary beverages like soda and sweetened teas are linked to increased risks, particularly in men.
