Everything you need to know about Colon Cancer

Cancer of the colon or rectum also called colorectal cancer, is located at the digestive tract’s lower end. It is a malignant tumor that begins in the large intestine.


Old age
Hereditary: colorectal cancer can be passed on through genes
Poor diet and lifestyle is a factor that contributes to colon cancer
Mainly high fat, more red meat and low fiber diet can cause such problems
Chronic smoking and alcohol consumption


  • Change in the consistency of your stool might be a symptom of colon cancer. Look out for persistent change in your bowel habits
  • Rectal bleeding or blood in your stool
  • If you’re experiencing cramps, gas, or any abdominal discomfort, it might be a symptom of colon cancer
  • Weakness or fatigue
  • Unexplained weight loss
  • If you get a feeling that your bowel doesn’t empty completely after your visits to the loo, you may have colorectal cancer.

The most important point to note is, one should never self-diagnose. If you think you’re experiencing symptoms of a disease or ailment, no matter how big or small, always consult a family doctor, general practitioner, or an oncologist (a doctor who treats cancer).


  • Colonoscopy: a thin fiber-optic instrument is inserted into the colon for examination
  • Biopsy: tissues removed from the living body for testing
  • Molecular testing of the tumour
  • Blood tests
  • Diagnostic imaging tests such as CT scan, MRI scan, and X-ray
  • Ultrasound

Treatment of colorectal cancer is based on the size, location, and how far cancer has spread

Some common treatments include:

  • surgery to remove cancer
  • chemotherapy
  • radiation therapy


  • Get screened or get diagnostic imaging tests. Screenings are tests that look for cancer before signs and symptoms develop
  • Follow a healthy diet; eat your greens, fruits, and whole grains
  • Exercise regularly
  • Obesity is said to be a cause of colon cancer. Control your BMI by following a healthy lifestyle
  • Quit smoking as it leads to many more injurious diseases as well
