About EXACT Sciences Corporation (EXAS):

EXACT Sciences Corporation is applying advances in genomics to facilitate the early detection of common cancers. The Company's stool-based, DNA technology offers the most accurate, non-invasive diagnostic available for the detection of colorectal cancer (CRC). CRC is the 2nd leading cause of cancer deaths and according to the American Cancer Society's journal, screening has been shown to have the biggest impact on improving mortality, over treatment and behavior modification. Despite this, more than half of the 87 million people over the age of 50 who should be adequately screened are not, and this rate increases by approximately four million each year.

EXACT Sciences has a commercial partnership with Laboratory Corporation of America (LabCorp.), which offers a simple, non-invasive CRC screening test based on EXACT's proprietary technologies. EXACT Sciences also aims to exploit new opportunities within CRC, such as staging and monitoring, and pursue new opportunities in other cancers.
