How to diagnose Colon Cancer?
Colon cancer, also called as colorectal cancer, is the sixth common cause for the death due to cancer. It is the third most common form of cancer which mainly affects individuals aged 45 or above. Therefore, it is advised to get the screening done every second and third year for colon cancer after the age of 45 years.
The oncologist may suggest any one or combination of the following test for the diagnosis of the colon cancer depending on the symptoms:
- Carcinoembryonic antigen (CEA) essay
- Digital rectal exam
The oncologist may suggest certain other tests for cancer patients to find the cancer cells inside the rectum and colon or other body parts. These tests may include CT scan, PET scan, MRI, and endoscopic ultrasound (EUS).
