Colonoscopies might not be anyone’s idea of fun, but they save lives every single day. As uncomfortable as the thought of the procedure may be, it’s one of the most effective tools we have for detecting colon cancer early, preventing it altogether, and addressing other silent issues in the digestive tract.
Understanding the real value of a colonoscopy, and when to get one, could be the difference between catching something early… or too late.
The Lifesaving Power of a Colonoscopy
A colonoscopy is a medical procedure where a gastroenterologist uses a thin, flexible camera to examine the inside of your colon and rectum. While it’s often used to investigate symptoms like rectal bleeding or persistent abdominal pain, its greatest power lies in prevention.
During a routine colonoscopy, doctors can:
- Detect and remove polyps before they become cancerous
- Identify signs of inflammation, ulcers, or bleeding
- Diagnose conditions like Crohn’s disease, ulcerative colitis, or diverticulosis
- Catch colorectal cancer at its earliest, most treatable stage
According to the World Health Organisation, colorectal cancer is the second leading cause of cancer-related deaths, yet it’s also one of the most preventable.
When Should You Get a Colonoscopy?
Timing matters. Here’s a general guide:
Age 45 or Older
For average-risk adults, the first colonoscopy is recommended at age 45. This was recently lowered from age 50 due to rising rates of early-onset colorectal cancer.
Family History of Colon Cancer or Polyps
If a close relative had colon cancer or advanced polyps, you may need screening sooner and more frequently.
Symptoms That Warrant Immediate Screening
Don’t wait for age-based guidelines if you notice:
- Rectal bleeding
- Persistent changes in bowel habits
- Unexplained abdominal pain
- Unexplained weight loss
- Iron deficiency anemia
Even if you’re under 45, these symptoms mean it’s time to talk to a gastroenterologist like Dr Fernandes Mark Lee.
What Happens During a Colonoscopy?
Most patients say the prep is the hardest part. You’ll need to follow a special diet and take a laxative the day before to clear your colon.
During the procedure:
- You’ll be sedated and comfortable
- The doctor uses a scope to examine your colon
- Polyps can be removed on the spot
- The whole thing usually takes 30 to 60 minutes
- Most patients go home the same day and feel normal within hours
It’s a small investment of time for a potentially lifesaving outcome.

| “It’s too embarrassing.” | Colonoscopies are routine for doctors and extremely private for you. |

When to See a Specialist
If you’re over 45, have digestive symptoms, or a family history of colon issues, it’s time to speak to a gastroenterologist like Dr Mark Lee. You’ll get clear guidance on how often you’ll need follow-ups and whether any polyps found need further attention.
Conclusion
Colonoscopies don’t just diagnose disease, they prevent it. One screening could save your life. With expert care from gastroenterologists, such as Dr Fernandes Mark Lee, the process is safer, easier, and more effective than ever.
Don’t wait for symptoms to show up. Schedule your colonoscopy. Take control of your gut health, because early action saves lives.
