About Colorectal Cancer
Colorectal cancer (CRC) is the third most common cancer globally, with more than 1.9 million new cases reported in 2020, according to World Cancer Research Fund International. The US Preventive Services Task Force recommends that screening with stool DNA tests such as ColoAlert should be conducted once every three years starting at age 45. Each year in the US, 16.6 million colonoscopies are performed. However, roughly one-third of US residents aged 50-75 have never been screened for colon cancer. This gap in screening represents a $4.0B+ total market opportunity in the US.

The Company's flagship product is ColoAlert, an accurate, non-invasive and easy-to-use, early-detection diagnostic test for colorectal cancer based on real-time Polymerase Chain Reaction-based (PCR) multiplex detection of molecular-genetic biomarkers in stool samples.
