Common Colorectal Cancer Symptoms: What You Need to Know

Knowing what to look out for can make all the difference in catching colorectal cancer early. Here’s a breakdown of common symptoms that shouldn’t be ignored.

1. Changes in Bowel Habits

One of the earliest signs of colorectal cancer is a noticeable change in bowel habits. This can include:

  • Persistent diarrhea or constipation
  • Changes in stool consistency or shape (narrower stools)
  • A feeling of incomplete bowel evacuation

If these changes last more than a few weeks, it’s important to consult a doctor.

2. Blood in the Stool

Blood in your stool is a common symptom and can appear as:

  • Bright red blood, indicating bleeding from the rectum
  • Dark or black stools, which may signal bleeding higher up in the colon

While blood in the stool can be caused by other conditions like hemorrhoids, it’s vital to get it checked.

3. Unexplained Weight Loss

Losing weight without trying is often a red flag for many cancers, including colorectal cancer. This happens because the cancer may cause a loss of appetite or interfere with the body’s ability to absorb nutrients.

4. Fatigue and Weakness

Fatigue that doesn’t improve with rest can result from cancer-related anemia, which occurs when there’s chronic bleeding in the colon or rectum, leading to low red blood cell levels.

5. Abdominal Pain or Cramping

Persistent abdominal discomfort, such as pain, cramping, or bloating, can also be a sign of colorectal cancer. The pain may be caused by a tumor blocking the colon or irritation of the bowel lining.

6. Feeling of Fullness

A constant sensation of fullness, even after a small meal, could indicate a tumor pressing on the digestive tract. This symptom often appears in the later stages of colorectal cancer.

When to See a Doctor

If you experience any of these symptoms for more than a few weeks, it’s important to schedule an appointment with your healthcare provider. While these signs can be linked to other, less serious conditions, early screening and diagnosis can significantly improve outcomes if colorectal cancer is present.

Takeaway

Understanding the common symptoms of colorectal cancer is a key step in promoting early detection and improving survival rates. Don’t ignore persistent changes in your body—speak up and take control of your health. If you’re 45 or older, or have a family history of colorectal cancer, talk to your doctor about scheduling a screening.

By staying informed, we can catch colorectal cancer earlier and save lives.
