A method for detecting colorectal cancer in a human subject, comprising:

• measuring an expression level of hsa-miR-204-3p in a blood, serum, or plasma sample from the subject,
• comparing the measured expression level of hsa-miR-204-3p to a control expression level for a healthy subject;
• detecting an decreased level of hsa-miR-204-3p in the sample from the subject as compared to the control expression level from the sample from the healthy subject;
• wherein the decreased level of hsa-miR-204-3p indicates that the subject has colorectal cancer;
• and
• wherein the method further comprises treating the subject for the colorectal cancer or performing a diagnostic procedure on the subject with the colorectal cancer;
• wherein the treatment comprises surgery, radiotherapy, chemotherapy or a combination thereof, and
