What is Colorectal Cancer?

Both the colon and rectum are parts of the human digestive system. They tend to form a muscular, long tube referred to as the large intestine. The large intestine begins with the colon which is about 4 to 5 feet and the last few inches is rectum.

From the small intestine, partly digested food enters the colon, which then removes the water and needed nutrients from the food and then turns the remaining food into waste or stool. The stool passes into the rectum from the colon and comes out of the body through anus.

Colorectal Cancer:

A cancer that begins in the large intestine is called colon cancer (colon).

Colon cancer can affect anyone at any age, but it most frequently affects older people. Polyps, which are tiny, noncancerous (benign) collections of cells that grow on the inside of the colon, may also be a starting point.

Statistics of Colorectal Cancer:

Worldwide, colorectal cancer is the 3rd most diagnosed cancer in males and 2nd most diagnosed in females. 1.2 million cases were estimated to have been reported in 2008.

Types of Colorectal Cancer:

Adenocarcinoma :

Tumors that begin in the lining of internal organs are known as adenocarcinomas. The word "adeno" signifies "gland." These cancers develop from glandular cells, or cells that produce. They can form in a variety of organs, including the lung and the breast. Early tumours in colorectal cancer begin as tiny adenomatous non-pedunculated polyps that continue to grow and can eventually transform into malignant tumours.

Rarely found Colorectal Cancer:


A lymphoma is a type of cancer that begins in a lymph node, which is part of the immune system. It can, however, begin in the colon or rectum too


Carcinoids are cancers that begin in the intestine's unique hormone-producing cells. They frequently have no symptoms.

Colorectal Cancer risk factors include the following:

Old age

Family history of colorectal cancer or polyps

Different intestinal disorders like ulcerative colitis

Inherited genes from family

High fat, low fiber diet

Sedentary lifestyle



Over consumption of alcohol

Understanding the major signs of Colorectal Cancer:

Even if you have no family history of colorectal cancer or polyps, tell your doctor if you experience any of the symptoms listed below, regardless of your age. Colorectal cancer symptoms include the following:

Change in bowel habits: Colorectal cancer symptoms include constipation, diarrhoea, altered bowel movements, incomplete evacuation, and bowel incontinence, which are normally signs of other, less significant conditions.

Blood on or in the stool

Blood on or in the stool is by far the most visible of all the symptoms of colorectal cancer. However, it does not always imply cancer because bleeding in the digestive tract can be caused by a variety of conditions, including haemorrhoids, anal tears (fissures), ulcerative colitis, and Crohn's disease, to mention a few.

  • Abdominal or pelvic pain or bloating
  • Unexplained weight loss
  • Vomiting

Early screening to identify the condition:

Colorectal cancer screening can often detect it early, when it is small, hasn't spread, and may be easier to treat. Regular screenings can even help to prevent colorectal cancer. A polyp can grow into cancer over a period of 10 to 15 years. Screening allows doctors to detect and remove suspicious polyps before they develop into cancer.

There are several screening procedures that can find Colon Cancer:

  • Colonoscopy
  • Sigmoidoscopy
  • Fecal occult blood testing
  • Double contrast barium enema

Soon after turning 45, you should start getting screened for colorectal cancer if you fall into the high risk group. After that, you should continue getting screened periodically. Early detection of colon cancer results in a five-year survival rate of roughly 90%. Reach out to a Surgical cancer center in coimbatore in case you are having any signs of colorectal cancer.

Diagnosis of the condition that can help in identification:

Your doctor may suggest one or more of the following tests and procedures if your signs and symptoms suggest that you may have colon cancer:


Colonoscopy:A long, flexible, and thin tube connected to a camera and monitor allows a colonoscopy to see your whole colon and rectum. Your doctor may insert surgical instruments through the tube to take tissue samples (biopsies) for analysis and remove polyps if any questionable regions are discovered.


Blood tests:Blood test for serum marker - carcinoembryonic antigen (CEA) is usually done. This marker is more useful in the follow-up period to detect recurrence rather than in initial diagnosis


Virtual colonoscopy:This test, also known as a CT colonoscopy or virtual colonoscopy, involves swallowing a contrast dye and inflating contrast and air into the rectum before performing a CT scan (imaging made with the use of X-rays) of the abdomen and pelvis.
