Colorectal cancer is the third most common form of the cancer. While screening is an effective means of preventing it, many people fail to get a colonoscopy because of the invasive nature of the procedure and the preparation and sedation that goes with it. Check-Cap is a clinical-stage company developing C-Scan, the first capsule-based system for preparation-free, colorectal cancer screening. The capsule uses ultra-low dose X-ray and wireless communication technologies to generate information on the contours of the inside of the colon as it passes through it. This creates a 3D map that allows physicians to look for polyps and other abnormalities. We spoke to Alex Ovadia, CEO of Check-Cap, about colorectal cancer, why people avoid being screened as they should, and how the company’s C-scan capsule-based system works.
