Colon Cancer

About the Department

The largest intestine in your body is the colon that forms the final part of your digestive tract. In the majority of colon cancer cases, it starts with tiny, benign cluster of cells known as adenomatous polyps. Covering the inner walls of the colon, the polyps contain an excessive number of normal and abnormal cells that appear on the glands. With the passage of time, the growths that are abnormally large degenerate to form adenocarcinomas. 

If one has a condition known as familial adenomatous polyposis syndrome where they have genetic abnormalities, then there are more chances of such people developing colon cancer. For such cases, multiple adenomatous polyps form in the colon leading to colon cancer. This form of colon cancer generally runs in the family and usually happens before the age of 40.

There is another type of colon cancer that is also hereditary in nature known as nonpolyposis colorectal cancer (HNPCC) syndrome. However, in this case the colon cancer develops in the absence of the precursor polyps.

If there is a first degree relative like a parent or a sibling who has colon cancer, then the chance increases by two to three times for immediate family members to also develop colon cancer. 

At Fortis Bannerghatta, we aim to bring together path-breaking research, technological advancements in medical procedures along with a team of highly skilled cancer specialists to comprehend your cancer diagnosis and treatment along with designing your subsequent need for home care. We do not believe that your suffering helps in our way of approaching patient care. Hence we use minimally invasive surgical procedures that can help remove the cancerous mass whilst still being able to preserve the surrounding tissue.

Our Diagnostic Services

To formulate the right treatment plan begins with an accurate diagnosis. At Fortis, Bannerghatta, we only use the most advanced and modern techniques and tools that will help us to conclude the existence of a colorectal malignancy. Taking a hands-on methodology towards cancer screening and testing, we aim to diagnose the condition at the earlier stages where the chances of the treatment being a success is far more possible. 

Your specialist may prescribe the following diagnostic tests:

- Colonoscopy:

During this procedure, a thin tube that has a light is inserted into the colon and the rectum. Having a camera attached to the tube, it can check for polyps or any abnormal areas of cancer. 

- Virtual Colonoscopy:

This diagnostic test uses x-rays and with the help of computers generates 3-D images of the rectum and displays it on the computer screen. 

- Ultrasound:

This may include both endoscopic ultrasound (EUS) and 3-D transrectal ultrasound (TRUS) with the help of which the depth of the cancer may be evaluated. It can also additionally capture images and take tissue samples. 

- Probe-based confocal laser endomicroscopy (pCLE):

Using this diagnostic screening, it can correctly view tissue cells in the digestive tract at the cellular level. With the assistance of one of smallest microscopes’ in the world today, the doctor is able to remove the cancerous tissue with this process. 

Post reviewing the results of the first round of diagnostic screening, your specialist may recommend secondary diagnostic screenings for further verification. These may include:

  • CT Scan
  • MRI
  • PET Scan
  • Biopsy


At Fortis, we can imagine going through these diagnostic tests can be frightening. It is our objective to make our patients and their families aware of the effects of colon cancer and how they can play a proactive role in patient care. If you do have questions during any of these diagnostic screenings, then do not hesitate to discuss your concerns with your specialist at Fortis.
