There is colorectal cancer in my family and several years ago I had genetic testing that included some hereditary colorectal cancer genes. This testing came back negative. Is there any new genetic testing available now for other hereditary colorectal cancer genes?
Genetic testing for hereditary colon cancer has expanded over the past few years. Three new hereditary colorectal cancer and polyposis genes have recently been discovered. Testing is now available for these genes for individuals who have personal and/or family histories suggestive of these syndromes.
