Bowel cancer is one of the most preventable cancers — when it’s found early. Detecting and removing pre-cancerous polyps can stop cancer before it starts. And, when bowel cancer itself is detected early, it’s often completely curable.
I’m Dr Tim Lyon, lead endoscopist for Colonoscopy Clinic on the Sunshine Coast. Here’s why early detection matters — and how you can take simple steps to protect yourself, whatever your age.
Why early detection matters?
Most bowel cancers start as small growths on the bowel wall called polyps. These can take up to 10 years to become cancerous, but can be easily removed during a colonoscopy long before they cause harm.
Finding and removing polyps early means less invasive treatment, better outcomes, and often avoiding major surgery altogether.
Do I need symptoms to get a colonoscopy?
Absolutely not. Most people with early bowel cancer feel perfectly healthy.
A colonoscopy is one of the most powerful tools to detect and remove polyps before they turn into cancer.
Even if you feel well, talk to your GP about screening — especially if you’re over 45 or have an increased risk of bowel cancer.
Who’s at higher risk of bowel cancer?
You may be at increased risk if you:
- Have a family history of bowel cancer or polyps
- Lead a sedentary lifestyle
- Carry excess body weight
- Eat a lot of processed or red meat
- Drink alcohol excessively or smoke
If any of these risk factors apply to you, speak with your GP about starting screening earlier.
What symptoms should I watch for?
Be alert to:
- Blood in your stool or rectal bleeding
- Unexplained changes in bowel habits
- Ongoing abdominal pain, bloating or cramping
- Unexplained weight loss or fatigue
- A feeling that your bowel doesn’t empty completely
If you notice any of these symptoms, see your GP as soon as possible.
But remember — most early bowel cancers don’t cause symptoms, which is why proactive, regular screening is so important.
Do I really have to wait until I’m 50?
No. You can start earlier.
If you’re 45–49, you can now request to join the National Bowel Cancer Screening Program and receive a free test kit before you turn 50.
If you’re under 45 and have symptoms or a family history, talk to your GP about starting screening earlier. We’re increasingly seeing advanced polyps – and even cancer – in younger and younger patients, sometimes in their 20s.
At Colonoscopy Clinic, we believe age should never be a barrier to early detection.
What is the National Bowel Cancer Screening Program?
This free Australian Government program sends eligible Australians a simple home test kit to check for hidden blood in your stool — an early warning sign of bowel disease. When you turn 50, you’ll receive the kit in the mail.
If your result is positive, your GP will refer you for a colonoscopy to investigate for polyps or cancers before it’s too late.
It’s a simple step that could save your life.
