March is Colorectal Cancer Awareness Month. The International Agency for Research on Cancer (IARC) estimates that in 2020 colorectal cancer was the third most commonly diagnosed cancer type in the world, with almost 2 million new cases. It was the third most common cancer in men but the second most common cancer in women, after breast cancer. Colorectal cancer was also the second most common cause of cancer death worldwide, causing almost 1 million deaths.
In this video, Dr Béatrice Lauby-Secretan of the Evidence Synthesis and Classification Branch at IARC explains how the IARC Handbooks of Cancer Prevention programme evaluated the effectiveness of colorectal cancer screening methods in reducing colorectal cancer incidence and mortality. This information enables governments and public health organizations to take action against this disease in the most effective way.
