Colon cancer is a type of cancer that occurs in the colon (large intestine/bowel). It is also referred to as colon, rectal, or colorectal cancer depending on where it develops. When the tumor starts in the rectum, it is called colorectal cancer.
Colon cancer usually starts as small non-cancerous polyps which form on the inside of the colon. Over time, these polyps grow bigger and turn into colon cancer.
With colon cancer, the symptoms may vary based on the size of the tumor, where it is located, and how far it has spread in the large intestine. The most common symptoms that colon cancer diagnosed patients experience are:
Tiredness and regular fatigue
Sudden loss of weight/appetite
Constipation or Diarrhoea
Blood/mucus in stools/narrow stools
Bowel discomforts like abdominal pain or excessive gas

The stages of colon cancer are as follows:
This is the earliest stage of colon cancer in which the cancer is limited to the mucosa (the inner lining of the colon).
Cancer has spread to the next layer of the colon, the submucosa. It may have also grown into the muscular layer of the colon.
Stage 2 colon cancer is categorized into three sections: 2A, 2B, and 2C.
Stage 3 colon cancer is divided into three sections: 3A, 3B, and 3C.
There are three stages of stage 4 colon cancer: 4A, 4B, and 4C.
The exact cause of colon cancer is unknown. But, there are various risk factors that can increase the chances of developing colon cancer.
Although people of any age can get develop colon cancer, the majority of people who are diagnosed with this disease are above 50 years.
People with a family history of colon cancer are more likely to develop the disease than people who don’t. Inherited syndromes like familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC) can also increase colon cancer risk.
The probability of developing colon cancer increases if a person previously had colon cancer or colon polyps (noncancerous).
People who consume Alcohol and Tobacco are at a higher risk of developing colon cancer.
Obese people make up for a higher number of colon cancer patients and have a higher risk of dying from the disease. Book an appointment at our Gastroenterology Hospital in Malleshwaram Bangalore to know about the treatment options.
A typical diet that has low fiber, high fat/calories, and red and processed meat is also found to be a risk factor for colon cancer.
Inflammatory intestinal illnesses (Crohn's disease and ulcerative colitis) can increase the colon cancer risk.
The treatment for colon cancer or colorectal cancer depends on the stage of your cancer based on which doctors suggest surgery, chemotherapy, or radiation therapy.
Surgery: Resection and anastomosis/colostomy /ileostomy – Usually performed in the last stage of the colon or colorectal cancer, a portion of the colon that contains the cancerous cells is removed. Visit Manipal Hospitals to know more about Colon Cancer Treatment in Malleshwaram Bangalore.
Chemotherapy interferes with cell division by disrupting the DNA and damaging the cells.
Radiotherapy is used to kill the cancer cells by using high-energy gamma rays.
Targeted therapy by using drugs that enter the bloodstream and function against cancers in the different parts of the body where cancer may have spread.
SEMS Placement for Obstruction: Using a self-expanding metallic stent (SEMS) at the sigmoid colon help in opening the blockage in the bowel and improve the symptoms. These stents are inserted using an endoscope. The stents usually expand up to 20 mm in diameter and are known to provide relief for symptoms like constipation, abdominal pain, bloating, or nausea.
It is often difficult to identify the presence of colon cancer in the early stages of developing the disease. Doctors suggest regular screening tests to prevent the disease early by removing the polyps before it becomes cancerous.
