The Importance of Regular Colorectal Cancer Screenings: Detecting Issues Early

What is Colorectal Cancer?

Colorectal cancer is a disease that starts in the colon or rectum. These are parts of the large intestine, which helps your body digest food. Cancer happens when cells in these areas grow out of control. As a result, tumors can form and may spread to other parts of the body. Colorectal cancer is sometimes called colon cancer or rectal cancer, depending on where it starts.

Why Early Screening Matters

Early screening for colorectal cancer can save lives. When doctors find cancer early, treatment is more likely to work. In fact, early detection of colorectal cancer often means the cancer is smaller and has not spread. Because of this, people have a better chance of recovery. According to the CDC, regular colon cancer screening can prevent many deaths each year. Screening can also find growths called polyps before they turn into cancer.

Symptoms and Risk Factors

Many people with early colorectal cancer have no symptoms. However, as the cancer grows, some signs may appear. It is important to know these symptoms and risk factors:

  • Blood in your stool or on toilet paper
  • Changes in bowel habits, such as diarrhea or constipation
  • Stomach pain or cramps that do not go away
  • Unexplained weight loss
  • Feeling very tired all the time

    • Some people have a higher risk of getting colorectal cancer. For example, your risk increases if you:

  • Are over age 45
  • Have a family history of colon or rectal cancer
  • Eat a diet low in fiber and high in red or processed meats
  • Smoke or drink alcohol often
  • Are overweight or do not exercise
  • Have certain health conditions, like Crohn’s disease or ulcerative colitis

    • How Colorectal Cancer is Diagnosed

    Doctors use several tests to diagnose colorectal cancer. First, they may ask about your symptoms and medical history. Next, they might do a physical exam. If they suspect cancer, they will order tests such as:

  • Colonoscopy: A doctor uses a thin, flexible tube to look inside your colon and rectum.
  • Stool tests: These check for blood or abnormal DNA in your stool.
  • Imaging tests: Scans like CT or MRI help doctors see inside your body.

    • If a test finds something unusual, the doctor may take a small sample of tissue, called a biopsy, to check for cancer cells.

    Screening Methods and Recommendations

    Screening means checking for cancer before you have symptoms. Because early detection of colorectal cancer is so important, experts recommend regular screening for most adults starting at age 45. The US Preventive Services Task Force supports this guideline. Screening methods include:

  • Colonoscopy: Done every 10 years if results are normal.
  • Stool tests: Some are done yearly, like the fecal immunochemical test (FIT).
  • Flexible sigmoidoscopy: Checks part of the colon every 5 years.
  • CT colonography: Also called virtual colonoscopy, done every 5 years.

    • Your doctor can help you choose the best test for you. If you have a family history or other risk factors, you may need to start screening earlier.

    Prevention Tips and Healthy Lifestyle Guidance

    While not all cases can be prevented, you can lower your risk of colorectal cancer by making healthy choices. For example, you can:

  • Eat plenty of fruits, vegetables, and whole grains
  • Limit red and processed meats
  • Stay active and exercise regularly
  • Maintain a healthy weight
  • Avoid smoking and limit alcohol
  • Get regular screenings as recommended

    • These steps can help prevent colon cancer and improve your overall health.
