Did you know that early screening can reduce colorectal cancer-related deaths by 90%? Colorectal cancer, which affects the cells of the colon and rectum, is the second leading cause of cancer-related deaths among individuals aged 50 to 74.
The idea of a colonoscopy might cause some anxiety, but it is a invasive procedure that plays a crucial role in early detection, ultimately saving lives. Learn more in our article!

Why get a colonoscopy?
Colorectal cancer develops silently in the colon and/or rectum, often starting from small polyps that can become dangerous over time. In 2024, it is estimated that over 25,200 Canadians were diagnosed with colorectal cancer, and nearly 9,400 people lost their lives to it.
A colonoscopy is an effective procedure that not only detects polyps before they become malignant tumors but also allows for their immediate removal, reducing the risk of cancer. By acting early, you take a vital step in safeguarding your health.
Who should get a colonoscopy?
In Quebec, the colorectal cancer screening program is recommended for individuals aged 50 to 74 who have no symptoms or personal or family history of the disease. However, if you experience symptoms or are considered at risk, screening may be recommended before the age of 50.
Before undergoing a colonoscopy, a fecal immunochemical test (FIT) is usually suggested. This test is simpler and less costly than a colonoscopy but carries the risk of overdiagnosis and overtreatment.
A colonoscopy may be recommended in several cases:
- You had a FIT, and results indicate blood in your stool.
- You are experiencing symptoms of colorectal cancer (see below).
- You have a personal and/or family history of colorectal cancer or polyps.
- You have other significant risk factors (see here).
Discuss your screening plan with your doctor or gastroenterologist to determine what’s best for your situation.
Symptoms to watch for
Colorectal cancer does not always cause symptoms, especially in its early stages. That’s why early screening is so important. However, be mindful of any unusual signs and consult a healthcare professional promptly if you experience:
- Persistent abdominal pain or cramps: Bloating, cramps, nausea, or vomiting could be linked to inflammation or lesions in the colon.
- Changes in bowel habits: Persistent diarrhea or constipation lasting more than a few weeks should be evaluated.
- Rectal bleeding or blood in stool: This is often overlooked but can indicate abnormalities in the colon or rectum.
- Unexplained weight loss: Sometimes, cancer affects appetite or metabolism.
- Unusual fatigue: This may result from anemia caused by unnoticed blood loss.
Risk factors
Certain factors related to your health and environment can increase your risk of developing colorectal cancer. Talk to your doctor if you have:
- Personal or family history: If you or a close relative have had colorectal cancer or polyps, your risk is higher.
- Age over 50: The risk of colorectal cancer increases with age.
- Specific medical conditions: Inflammatory bowel diseases such as ulcerative colitis or Crohn’s disease can damage the intestinal lining. People with diabetes also have a higher risk.
- Lifestyle factors: A high-fat, low-fiber diet, obesity, smoking, excessive alcohol consumption, and a sedentary lifestyle are contributing factors. Your doctor can help guide you towards a healthier lifestyle.

What happens during a colonoscopy?
A colonoscopy is a invasive procedure that allows a doctor to examine the inner lining of the colon and rectum using an instrument called a colonoscope. This flexible tube has a small camera that captures real-time images, helping detect polyps or other abnormalities. It is typically performed in a hospital or clinic endoscopy unit.
The procedure lasts approximately 30 to 60 minutes:
- You will receive sedation or anesthesia to ensure your comfort.
- You will lie on your left side with your knees pulled up toward your chest.
- The gastroenterologist will gently insert the colonoscope through the rectum and guide it through the colon to inspect the intestinal lining.
- If polyps or suspicious lesions are found, tissue samples (biopsies) may be taken for further analysis.
- You may experience mild discomfort such as cramping, bloating, or a temporary urge to use the restroom.
How to prepare for a colonoscopy?
During your pre-endoscopy consultation, a nurse will provide you with detailed instructions to ensure a successful procedure and accurate results. Preparation generally includes:
Before the colonoscopy
- Diet: One or more days before the exam, your doctor may recommend a low-fiber or liquid diet and advise you to avoid certain foods and colored beverages.
- Medications: Inform your doctor about all medications you take, as some may need to be adjusted.
- Bowel preparation: You will need to take a prescribed laxative solution to cleanse your colon the day before and the morning of the procedure.
- Fasting: You may be required to refrain from eating or drinking for a few hours before the procedure.
After the colonoscopy
- Rest: You will need to stay at the clinic for about an hour after the procedure and rest for the remainder of the day.
- Transportation: Since sedation can temporarily affect reflexes, you will need someone to accompany you home.
- Follow-up appointment: Your medical team may schedule a follow-up visit to discuss results and next steps.
