Colon Cancer

Carcinoid Tumours


The colon, also known as the large intestine, is the last segment of the digestive tract in the human body. Colon cancers are cancers that affect this portion of the body. They’re also known as large bowel cancer or cancer of the large intestine.

Colon cancers are caused by a variety of factors that aren’t fully understood. Due to a DNA error, healthy cells in the colon can continue to divide even though new cells are not needed. Colon cancer usually starts as a small cluster of cells known as polyps. These polyps may not be cancerous at first (benign). These polyps will eventually transform into colon cancer, says Dr. Sanjoy Mandal, who is considered to be the best cancer surgeon in Kolkata.

Symptoms and Warning Signs

Colon cancer usually does not cause any symptoms in its early stages. In addition, the signs of colon cancer differ depending on the size and position of the cancerous polyps. According to the oncologist in Kolkata, the following are some early signs and symptoms of colon cancer in both men and women:

  • Bleeding from the anus (rectum), as well as blood-stained stools
  • A significant change in bowel habits (constipation or diarrhoea), persisting for over four weeks
  • Consistent abdominal distress with symptoms such as gas, cramps, or pain
  • A persistent sensation of incomplete bowel emptying
  • Weakness or exhaustion
  • Unexplained weight loss

Who is More at Risk

The factors that increase your risks of having colon cancer, as discussed by the oncology specialist in Kolkata, are:
  • Older age (more than 50 years)
  • A history of polyps or colorectal cancer
  • Colon cancer in the family
  • Intestinal inflammation (e.g., Crohn’s disease and ulcerative colitis)
  • Inheritance of some conditions of colorectal cancer and polyps
  • Insulin resistance and diabetes
  • Lifestyle-related risks like sedentary lifestyle, smoking, excessive alcohol consumption, and intake of a high-fat, low-fibre diet
  • Exposure to radiotherapy

Colon Cancer Treatment in Kolkata

The type of colon cancer treatment is primarily determined by the cancer’s level. Discuss various treatment choices with your oncologist. Surgery, chemotherapy, and radiotherapy are the three main treatment methods, followed by supportive care. The oncologist will recommend the appropriate treatment plan based on the severity of the disease. Follow the oncologist’s instructions to get the best treatment outcomes.

Surgical Removal

In order to control the growth and spread of cancer, the oncology surgeon in Kolkata may decide to remove the colon polyp, colon tumour, and lymph node, depending on the diagnosis. To prevent a blockage of the colon due to cancer, surgical procedures can include the placement of a stent.
Your doctor will assist you in deciding which surgical technique is best for you. Dr. Sanjoy Mandal performs laparoscopy and minimally invasive operations, such as colectomy or diverting colostomy, in order to improve the chances of a quicker recovery.
