The Silent Rise: Why Colorectal Cancer is Increasing in Adults

Provider talking to patient

Colorectal cancer was once considered a disease that mainly affected older adults—but that’s changing. Over the last two decades, doctors have seen a steady rise in colorectal cancer among people under 50. While researchers are still studying why this trend is occurring, lifestyle factors such as diet, weight, and physical activity may play a role.

The good news? Colorectal cancer is highly preventable and treatable when caught early. That’s why updated national guidelines now recommend starting regular screening at age 45 instead of 50. Screening can find precancerous growths, called polyps, before they turn into cancer—or detect cancer early, when treatment is most effective.

If you’re 45 or older, talk with your provider about which screening option is right for you. Whether it’s a colonoscopy or an at-home stool-based test, the best screening is the one that gets done.

Don’t wait for symptoms—early detection saves lives.

FAQs About Colorectal Cancer Screening

Is colorectal cancer preventable with screening?

Yes. Screening can find polyps before they turn into cancer and detect cancer early, when treatment works best. Increased screening has contributed to lower colorectal cancer rates in older adults.

Do I need to get screened for colorectal cancer?

Yes. Adults at average risk should begin screening at age 45. If you have risk factors such as family history, certain medical conditions, or lifestyle factors, your provider may recommend starting earlier.

When should I get screened?

Most people should start at 45. Start earlier if you:

  • Have symptoms
  • Have a family history of colorectal cancer or polyps (typically age 40, or 10 years before the youngest case)
  • Have certain genetic conditions
  • Have a personal history of cancer or chronic bowel disease.

Talk with your provider to determine the right timing for you.

What are the symptoms of colorectal cancer?

Symptoms can include changes in bowel habits, abdominal pain, rectal bleeding, or fatigue. These can be caused by many conditions, so any new symptoms should be evaluated promptly. Don’t wait—early detection saves lives.

How can I convince someone to get screened?

Start by asking if they’ve considered screening and understand what concerns may be holding them back. Offer support, share why screening matters, and consider leading by example by getting screened yourself.

What should I do if I still have questions?

Talk with your healthcare provider about screening options, timing, and any concerns you may have.
