Colon cancer is the most common form of cancer found in humans these days. But it is very important to detect colon cancer early. People might get confused as to which test can detect colon cancer, whether it is a CT scan or not. In this blog, we’ll explore how CT scans are used in detecting colon cancer, their effectiveness, and other diagnostic methods that might be more appropriate depending on your health. 

We’ll also explain when a CT scan is typically recommended and its limitations, helping you make informed decisions about your health. Plus, August’s WhatsApp Health Assistant is available to give you personalized advice on cancer screening and next steps.

What is a CT scan?

A CT (computed tomography) scan is a way to create detailed cross-sectional images of your body. It is a medical imaging process. It allows doctors to check the internal organs, tissues, and other internal structures with more precision than traditional X-rays. This makes it a valuable tool for detecting various conditions, including cancer.

Can a CT scan detect colon cancer?

Yes, a CT scan can detect colon cancer, but it is not the primary method used for screening or initial diagnosis. Here’s why:

1. Detailed imaging: CT scans help to get a detailed image of the disease. Most of the time it’s done after cancer is diagnosed to check how much the cancer has spread inside the body. 

2. Treatment plan: A CT scan is mostly done after the disease is diagnosed to check the stage of the cancer, and thus the treatment plan is done depending on this. 

3. Emergency situation: A CT scan can be done to quickly check any emergency symptoms, such as bowel obstruction or severe pain. 

Limitations of CT Scans in Detecting Colon Cancer

CT scans are helpful for a complete diagnosis, but it is not the actual process through which they detect cancer. Here are a few reasons why:

1. Early Signs: Early stage detection plays a crucial role in cancer treatment. CT scans cannot identify initial levels of tumours or polyps. Early-stage detection usually requires more specialized procedures.

2. Unnecessary Findings: Sometimes CT scans show results with unnecessary findings, which may not require the attention exactly at the time of cancer diagnosis and treatment. 

3. Radiation Exposure: CT scans involve exposure to radiation. And people who undergo frequent imaging may get risks because of radiation. While the risk is generally low, other non-radiation-based screening methods may be preferable for regular cancer screenings.

What Is the Best Test for Detecting Colon Cancer?

CT scans play an important role in colon cancer. But patient’s need a test, which will be useful for early diagnosis. The most common methods for detecting colon cancers are as follows: 

1. Colonoscopy: This is one of the most used tests to detect colon cancer. Any suspicious polyps can be removed and biopsied during the procedure, making it both a diagnostic and preventive tool. 

2. Stool Tests: Tests like the Fecal Immunochemical Test (FIT) or the Fecal Occult Blood Test (FOBT) are non-invasive and check for hidden blood in the stool, which can be an early sign of colon cancer. While these tests are convenient, they are less specific and may require follow-up with a colonoscopy if results are abnormal. 

3. Sigmoidoscopy: It’s similar to a colonoscopy; this test examines only the lower part of the colon. While it’s less invasive, it may miss polyps or cancers in the upper part of the colon.

4. CT Colonography (Virtual Colonoscopy): CT colonography creates detailed images of the colon and rectum. It’s less invasive than a colonoscopy and is a variation of colonoscopy. But still involves some radiation exposure.  If abnormalities are detected, a follow-up colonoscopy may be necessary.

When is a CT scan used in colon cancer diagnosis?

Although CT scans cannot detect cancer as the very first step, there are a few other times when CT scans are being used in colon cancer diagnosis.

1. Assessing Cancer Spread (Staging): A CT scan helps you diagnose at which stage the cancer is at present time. It will analyse the areas where the cancer has spread. This staging information is vital for creating a treatment plan.

2. Guiding Treatment: A CT scan helps surgeons plan the surgery by analysing where the cancer has spread and checking the stage of the cancer. 

3. Monitoring After Treatment: In some cases, CT scans are done to check the progression of the disease, or if the patient has taken medication, then how is the progression? 

How Effective Are CT Scans Compared to Other Tests?

CT scans are most effective for colon cancer detection and metastasis (the spread of cancer), but they are less effective for early detection. Colonoscopy is the most effective and standard test for early detection of colon cancers.
