Understanding Colon Cancer

Before diving into when screening should start, it’s essential to understand what we’re dealing with. Colon cancer, also known as colorectal cancer, starts in the colon or rectum. It often begins as small, benign (non-cancerous) clumps of cells called polyps. Over time, some of these polyps can become colon cancers.

Why Is Screening Important?

Screening tests help identify the cancer in people who don’t have any symptoms. It’s like finding a needle in a haystack before the needle becomes a bigger problem.

  1. Early Detection: Catching cancer early often means it’s more treatable and may have better outcomes.
  2. Finding Polyps: Screenings can also detect those sneaky polyps before they become cancerous.
  3. Peace of Mind: Knowing you’re clear can offer a lot of relief.

The Recommended Age for Colon Cancer Screening

Let’s answer the pressing question: “What age should colon cancer screening start?”

For most people, the recommended starting age is 45. However, this isn’t a one-size-fits-all answer. Here’s a more detailed breakdown:

General Population

For those without any increased risk factors (like a family history), the general recommendation is to begin screening at age 45. This advice comes from many prominent health organizations who’ve conducted extensive research on the topic.

High-risk Individuals

For people with:

  • A family history of colon cancer
  • Known genetic predispositions (like Lynch syndrome)
  • A history of inflammatory bowel disease

The screening might need to start earlier. It’s essential to consult with a healthcare provider about when and how often to get screened if you fall into this category.

When Should Screenings End?

This is another crucial aspect. Generally, if you’re 75 or older, you might not need regular screenings unless you have specific risk factors. Again, your doctor is the best guide here.

Methods of Screening

It’s not just about when but also how. Here are common methods for colon cancer screening:

  1. Colonoscopy: This is a procedure where a doctor checks the colon and rectum using a long, flexible tube. It’s the most comprehensive test and can remove polyps during the procedure.
  2. Stool tests: These tests check for blood or cancer DNA in your stool. They’re less invasive than a colonoscopy but might require more frequent testing.


Cancer is a word that can send chills down anyone’s spine, but knowledge is power. Now that you know when colon cancer screening should start, you’re empowered to take charge of your health. Remember, while 45 is the general recommendation, your personal and family medical history can influence this. Always consult with your healthcare provider to make the best decision for you.
