Up to 38.6% of people with colon cancer who have a hereditary cancer syndrome—including 6.3% of those with Lynch syndrome—could have their conditions remain undetected with current universal tumor-screening methods, and at least 7.1% of people with colorectal cancer have an identifiable inherited genetic mutation, according to new data published by scientists at The Ohio State University Comprehensive Cancer Center—Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC—James).
