Colon cancer is also know as colorectal cancer (colon cancer and rectal cancer)  and bowel cancer. The colon is basically where the body extracts water and salt from solid wastes. The waste then moves through the rectum and gets out from the body through the anus. Further colon cancer symptoms appear slowly and not immediately seen.

Colon cancer originates from the benign tumors (noncancerous cells) and they are called adenomatous polyps. The adenomatous polyps are present in the inner walls of the large intestine.

It is the cancer that develops from the colon or rectum ( parts of large intestine). It is considered to be the third most common type of cancer in United States.

What Are The Causes Of Colon Cancer ?

The exact causes are not known but in this subheading we will be talking about some of the potential risk factors.

1. Polyps: As mentioned above that colon cancer originates or begins from the precancerous polyps that exist in the large intestine. The most common types of polyps are: Adenomas, Hyperplastic polyps. And some of these polyps may even grow into malignant colon cancer, if not removed during the early stages.

2. Genes: Rapid growth may occur if there is any genetic damage, or if changes in the DNA and check points affect the cell divisions. Colon cancer can also be inherited, but as seen according to the reports that colon cancer occur in people without a family history. For some it may be by birth and they may carry mutations already that make them have the disease in their later life.

3. Traits, Habits, and Diet: Age plays an important role in here. 92 percent of the individuals are those who get a diagnoses are over 50 years old. Sedentary lifestyles, obesity and people who smoke eat tobacco make people more prone to colon cancer. Colon cancer is directly linked with the digestive system so the calories, red meat, processed meat and alcohol are alll attached with higher risk of colon cancer.


How To Diagnose Colon Cancer ?

Whenever a patient visit the physician they carry out whole physical exam and ask about your family history as well. The physicians diagnose only after colonoscopy or a barium enema x-ray.


  • Colonoscopy: In colonoscopy there is a long flexible tube with a camera attached to one end of the tube, and it is directly inserted into the rectum to get the details of inside the colon.

In order, a patient has to keep a check on their special diet, as it has to be followed during this process, the diet duration is of 24-48 hours before the procedure.

If polyps are found during the examination in the colon, they are removed with the help of the tube and send for further investigation to the pathologist for the biopsy. The pathologist examines the sample under the microscope that detects cancerous cells or precancerous cells.

  • Double-contrast barium enema: It is an x-ray procedure in which it uses a liquid called barium to provide clearer imaging results than a standard x-ray can give. But before undergoing this procedure the patient need to undergo for fast for several hours.

A liquid solution containing barium is then injected into the colon through the rectum, followed by pumping of air to smooth barium layer.


How To Treat  Colon Cancer ?

Treatments depend mainly on the type of the cancer, age of an individual and many more. As such there is no common treatment, but surgery, chemotherapy and radiation might be of great help in here.

  • Surgery: In surgery a part of colon is removed also known as colectomy. The affected part of the colon is removed or even the lymph node is removed by the surgeon.                                                                                            A stoma is the opening made in the wall of the abdomen. waste is passed into the bag, removing the need  of lower part of the colon also referred to as colostomy. Small and localized cancers can be removed using endoscopy.
  • Chemotherapy: In this there are chemicals that interfere with the cell division, and by this act the proteins or DNA is damaged. Such treatments can target tumor cells or even the healthy cells. Common side effects of the chemotherapy includes, 1. hair loss 2. nausea 3. fatigue and even 4. vomiting.
  • Radiation: Radiations damages and kills cancer by focusing high-energy gamma rays on them. Side effects of radiation in a individual may include 1.nausea 2.diarrhea 3. weight loss and appetite and many more.
