Why going to China for cancer treatment?

Tests and procedures used for colon cancer diagnosis include:

  • Using a scope to examine the inside of the colon. Colonoscopy uses a long, flexible and slender tube attached to a video camera and monitor to view the whole colon and rectum. A doctor may pass surgical tools through the tube to take tissue samples and remove polyps.
  • Removing a sample of tissue for testing. A biopsy is a procedure to remove a sample of tissue for testing in a lab. For colon cancer, the tissue sample is often collected during a colonoscopy. Sometimes surgery is needed to get the tissue sample. In the lab, tests can show whether the cells are cancerous and how quickly they’re growing. Other tests can give more information about the cancer cells. Your health care team uses the results to understand your prognosis and create a treatment plan.
  • Blood tests. Blood tests aren’t used to diagnose colon cancer. But blood tests can give clues about overall health, such as how well the kidneys and liver are working. A blood test might be used to look for a low level of red blood cells. This result might indicate that a colon cancer is causing bleeding.

    Colon cancers sometimes make a protein called carcinoembryonic antigen, also called CEA. Blood tests can track the level of CEA over time. The results might show whether the cancer is responding to treatment. After treatment, CEA blood tests might detect if the cancer comes back.

Colon cancer stages

After a colon cancer diagnosis, other tests might be needed to find out the extent of the cancer. This is called the cancer’s stage. The health care team considers the cancer’s stage when creating a treatment plan.

Staging tests might include imaging scans of the abdomen, pelvis and chest. Imaging tests take pictures of the body. They show the location and the size of the colon cancer. Often, doctors can’t be certain of the cancer’s stage until after colon cancer surgery.

Colon cancer stages range from 0 to 4. The lowest numbers mean the cancer is all inside the lining of the colon. By stage 4, the cancer is considered advanced and has spread to other areas of the body. When cancer spreads, it’s called metastatic cancer.

Many people with colon cancer don’t have symptoms at first. When symptoms appear, they’ll likely depend on the cancer’s size and where it is in the large intestine.
