Colorectal Cancer Types, Stages, Signs, Symptoms, Risk Factors, Diagnostic Procedures, Treatment, Specialists & Doctors

Colorectal cancer or bowel cancer is the abnormal or unusual growth of cells in the large  intestine (colon) or the rectum of our digestive system. It usually starts with the development  of polyps in the intestine. These polyps are usually harmless but can turn into cancerous cells, if not treated early.  

What are the types of colorectal cancer (bowel cancer)?

Though being the cancer of colon or rectum, it differs in nature based on the types of cancerous cells. It can be of various types: 

The most common type of colorectal cancer starts from adenocarcinomas which forms in the  cells that make the mucus within the colon or rectum. 

The other less common types includes those caused by other types of tumors such as  lymphomas which usually spread with lymph nodes in the colon; carcinoids which start in  intestine within hormone making cells and sarcomas which form in the soft tissues such as  muscles in the colon. 

What are the signs & symptoms of colorectal cancer (bowel cancer)? 

It is generally asymptomatic in initial stages; however, it may still be identified with some of  the most common symptoms that people suffering from this disease, might experience. They  are: 

  1. Changes in bowel habits 
  2. Diarrhea or constipation 
  3. Constant feeling of fullness 
  4. Blood in the feces 
  5. Bright red blood from rectum 
  6. Weight loss 
  7. Feeling tired or fatigue 
  8. Anemia

Though most of these symptoms not always are suggestive of colorectal cancer, immediate  consultation with an expert or nearby doctor should be done.

What are the stages of colorectal cancer (bowel cancer)?

To know the extent and seriousness of cancer, staging guidelines are used by doctors to provide and suggest the best possible treatments.  

In the earliest stages of colorectal cancer, the abnormal tissues may be present in the inner linings of the colon. In stage 1, they penetrate the lining of the colon. In stage 2, cancer may have spread to the walls of the colon or to the lymph nodes but hasn’t affected them yet. Stage 3 indicates the movement of cancer to the lymph nodes while in stage 4 or the final stage, cancer spreads from the colon to the other organs such as the liver or lungs. 

What are the risk factors of colorectal cancer (bowel cancer)? 

What exactly causes colorectal cancer is still unknown but certain factors aggravate or  heighten the risks of getting it. Some of the major risk factors include smoking, obesity,  having type 2 diabetes, following a sedentary lifestyle, consuming a diet containing processed  meats, etc. However, all these risks are avoidable and can be reduced by altering one’s  lifestyle. 

Other risk factors are rigid and hence can’t be changed or avoided. These include age, having  a history of polyps or other bowel syndromes, a lineage of colorectal cancer and/or having  certain genetic syndromes such as Crohn’s disease, Lynch Syndrome or adenomatous  polyposis.

What are the diagnostic procedures for colorectal cancer (bowel cancer)? 

On examining the symptoms, the doctor might suggest a series of tests and exams to examine the root and real cause and nature of the disease. The diagnostic procedures include: 

  1. Colonoscopy: This procedure includes the use of a colonoscope which contains a  camera and light, providing a full view of the colon and rectum. 
  2. Blood Stool Test: In this, a stool sample is analyzed for the traces of blood and other substances. 
  3. Stool Immunochemistry: This test helps to check hidden blood in the lower colon. It is also known as fecal immunochemistry. 
  4. Stool DNA Test: This test checks for various DNA markers that colon cancer or precancerous cells might shed into the stool. 
  5. Flexible Sigmoidoscopy: This procedure is used to examine the rectum and sigmoid colon. 
  6. Barium Enema X-Ray: It is used to reveal any unusual feature via the X-ray.
  7. CT Colonography: This is used to produce images of the colon. It is a predecessor of colonoscopy and its results suggest whether there is a need of colonoscopy or not.
  8. Imaging Tests: Ultrasound, CT scan or MRI scan are done to determine whether the cancer has spread to other parts of the body or not. 

All of the above procedures should be done in consultation with specialists and under their supervision to procure the best and most reliable results.

Depending upon the size and location of the tumor;  cancer stage; its nature- whether recurrent or not and person’s overall health, different kinds or combinations of treatments may be used. The various types of treatments include: 

  1. Surgery: It is the primary treatment which is done at early stages of cancer. It involves the removal of cancerous tissue or tumors from the body and prevents the cancer from spreading. 
  2. Chemotherapy: It is usually done in the later stages, mostly after the surgery, to destroy the remaining nods or cancer tissues and stop them from recurring or spreading. It involves a number of drugs such as Avastin, cyramza etc. 
  3. Targeted therapy and Immunotherapy: These are used to target a specific protein to slow down the growth of cancerous cells and to signal the immune system to eliminate specific cells respectively with the use of some specific drugs.
