Colon Cancer

Colon cancer, commonly known as colorectal cancer (CRC), is a condition that affects the large intestine. It is a type of cancer that develops in the colon or rectum. The large intestine is made up of colon, cecum, rectum, and anus.

The large intestine is where colon cancer mostly develops because of the colon's ability to absorb vitamins and nutrients from the food that has been digested and passed through it. It typically begins when abnormal cells develop out of control and infiltrate the rectum's wall and nearby tissue. One of the most prevalent cancers in adults is CRC. Given that men make up the large majority of cases, it is also one of the deadliest. Despite the fact that CRC is typically found in men, it can also affect women.

Signs and Symptoms

  • Bright red blood in the stool or maroon/black colour stool
  • Rectal bleeding
  • Persistent abdominal discomfort
  • Excessive gas and abdominal pain
  • Feeling of abdomen fullness even after not eating for a sometime
  • Fatigue or tiredness
  • Unexplained weight loss
  • Most of these symptoms may potentially signal other possible illnesses. Early on in the disease, colon cancer is often symptomless in many patients. When symptoms occur, they'll likely vary, depending on the cancer's size and location in your large intestine. Make an appointment with your gastroenterologist to talk about getting a rectal cancer screening if you experience any of these symptoms. Also do get screening if there is family history of colon cancer or rectal cancer.


    Regular screenings are advised for those who have had colon cancer in the past, are older than 50, have a family history of the disease, have Lynch syndrome, Crohn's disease, or adenomatous polyposis.

    • Keeping a healthy weight: Obesity and being overweight increase the chance of developing numerous malignancies, including colorectal cancer. If you want to gain weight, you can add healthy snacks to your day, restrict portion size, and engage in as much physical activity as you can.
    • Routine exercise: It has been demonstrated that consistent, moderate exercise significantly reduces a person's risk of acquiring colorectal cancer.
    • A balanced diet: Eat a diet high in fibre, fresh fruit and vegetables, high-quality carbs, and little red and processed meat.
