March is designated as Colon and Rectum cancer awareness month. Worldwide there are 1.93 million new CRC cases diagnosed, and 940,000 CRC caused deaths in 2020, representing 10% of the global cancer incidence. It is the third most common cancer worldwide. Two thirds of CRC occur in developed countries, because of longer life expectancy, however, the numbers are declining as screening, education, and treatments are offered and 5-year survival rate is 65% for all stages. In developing countries, however, there is increase in new cases because of adoption of unhealthy habits like eating western diets, increase in fatty foods, not exercising like in walking and Obesity. The median survival in developing countries e.g., in Ghana it is 15 months, and 5-year survival rate is 16%.


Symptoms or warning signs include change in bowel movements e.g. diarrhea or constipation, and shape of stool, recurrent abdominal pain, and bleeding from the rectum. Weight loss, tiredness or fatigue may also be present.

Lifestyle changes like exercise, weight loss, high fiber foods, and low-fat diet

Screening starting at age 45 years for those at average risk according to experts. Those with increased risk start earlier, e.g. if you have a parent with colon cancer

  • Screening for CRC saves lives and there has been a decrease in incidence and death due to screening.
  • There are six screening tests available. Three are Stool based and three are Visual.
  • Guaiac Fecal occult blood test- detects blood in stool. Done yearly
  • Fecal Immunochemical Test (FIT)- Detects human hemoglobin in stool. Done yearly
  • Stool DNA –looks for abnormal DNA and blood in stool. Done every 3 years e.g. Cologuard
  • Virtual Colonoscopy- 2 & 3 D images of colon viewed on a computer- Done every 5 years
  • Flexible sigmoidoscopy – Lighted tube checks rectum and lower third of colon, and polyps can be removed. Done every 5 years
  • Screening Colonoscopy- Lighted tube with camera looks inside the entire colon and polyps can be removed. Every 10 years

What test is done depends on many factors. You can discuss with your doctor. If any of the tests detect a problem, a follow up colonoscopy is usually performed.

Colon cancer if detected early is treatable. Treatment can be in the form of surgery, chemotherapy and or radiation depending on size, location and spread of the cancer.
