Colorectal Cancer Risk

    Last Updated: October 13, 2024

    Some dietary supplements are thought to reduce the risk of colonic cancer, and this is assessed by either epidemiological research showing a relationship or studies that note how supplementation can reduce a known biomarker of colon cancer.

    Summary

    Behind lung cancer, colorectal cancer[1] is the most common cause of cancer death and the fourth most common cancer after lung, breast, and prostate cancer. There were around 1.8 million cases of colorectal cancer worldwide in 2018, resulting in close to 900,000 deaths. Most colorectal cancer cases develop from benign tumors (adenoma) that undergo genetic changes[2] over time (at least 10 years) to ultimately become cancerous (carcinoma). This process, often called the adenoma-carcinoma sequence, is depicted in Figure 1.

    Early detection[4] through colonoscopy screenings is associated with reduced risk of recurrent colorectal cancer and death, and removal of colorectal adenomas appear to reduce the risk of colorectal cancer mortality[5] and incidence[6]. However, recurrence is common[7].
