New tumour testing methods can improve the accuracy of diagnosis
Although a strong genetic predisposition to colorectal cancer (CRC) is rare, it is important because of its large contribution to CRC diagnosed before the age of 50 years and because mortality from CRC can be reduced by appropriate management. There are currently limitations in determining whether a case of CRC is “sporadic” or whether it might be related to an inherited predisposition. However, Australian research that examines the utility of new diagnostic tools to help diagnose genetic tendency to CRC may be showing us a way forward.1,2
