Colorectal cancer (CRC) is the most common gastrointestinal (GI) cancer. According to the World Health Organization, globally, CRC is the third most common cancer in men and women combined, and the second most common cause of cancer-related deaths. Broken down by sex, CRC is the third most common cancer in men and the second most common cancer in women.

Distribution-wise, the majority of CRC cases occur in industrialized nations, including the United States, Canada, Japan, parts of Europe, New Zealand, Israel, and Australia. Recent rises in CRC incidence have been observed in many parts of Japan, China (Shanghai), and several Eastern European countries.

Despite the increased rates of patient adherence to CRC screening guidelines and early detection of disease, approximately 25% of patients with CRC have distal metastatic disease at the time of diagnosis; moreover, one half of patients with CRC will progress to metastatic disease.

The liver, lungs, and peritoneum are the most common metastatic sites of CRC. Although advances in biomolecular testing have resulted in improved treatment and outcomes of patients with CRC, the fundamentals of diagnosis remain an important aspect of survival.
