No increase in colorectal cancer in patients under 50 years of age: a Victorian experience from the last decade

Abstract

AIM: The study aimed to assess whether there has been an increase in the incidence of colorectal cancer (CRC) among young patients in Victoria and whether such cancers are more advanced at presentation. METHOD: The Victorian Cancer registry database was searched for patients, 18-50 years of age, diagnosed with CRC [young colorectal cancer (YCRC)] between 2000 and 2010.
