If you have some symptoms listed among those linked to colorectal cancer (e.g., blood in the stool), your doctor will follow a precise protocol to understand the cause of the symptom.
This is a 3-step study:
- Clinical observation by the physician;
- Imaging tests (to visualize and categorize any changes in the colon or rectum);
- If a change is found, the next step is a biopsy (to look at the tumor cells, determining if they are malignant or not, and if the answer is yes, what type of cancer).
This 3-steps approach allows a more thorough study of any changes, increasing the reliability of the diagnosis.
