Colorectal cancer is one of the most common and preventable cancers, yet it often goes undetected in its early stages. Recognizing the warning signs early can lead to timely diagnosis and treatment, improving survival rates and outcomes. Understanding these symptoms and seeking medical attention when necessary can make a significant difference.

Common Early Symptoms

Colorectal cancer may not always present noticeable symptoms at first, but as the disease progresses, individuals may experience:

• Changes in Bowel Habits: Persistent diarrhea, constipation, or a change in stool consistency lasting more than a few days.

• Blood in Stool: Bright red or dark-colored blood in the stool, which may indicate bleeding in the colon or rectum.

• Abdominal Discomfort: Persistent cramping, bloating, gas, or pain in the abdomen.

• Unexplained Weight Loss: Sudden, unintentional weight loss without changes in diet or exercise.

• Fatigue and Weakness: Feeling unusually tired or weak, which can be caused by anemia due to blood loss.

• Incomplete Bowel Movements: A sensation that the bowel does not empty completely.

When to see a doctor: 

If you experience any of these symptoms for more than a few weeks, it’s essential to consult a healthcare professional. While many of these symptoms may be related to other conditions, early detection of colorectal cancer can lead to more effective treatment options and improved survival rates.

Importance of Regular Screening

Since colorectal cancer can develop without noticeable symptoms, regular screenings play a vital role in early detection. The American Cancer Society recommends that individuals at average risk begin screening at age 45. Those with a family history or other risk factors may need to start earlier. Screening methods include:

• Colonoscopy: The most effective way to detect and remove precancerous polyps.

• Fecal Occult Blood Test (FOBT) or Fecal Immunochemical Test (FIT): These tests detect hidden blood in stool samples.

• Stool DNA Test: Identifies genetic changes associated with colorectal cancer.

Taking proactive steps

Aside from regular screenings, you can take steps to lower your risk of colorectal cancer by maintaining a healthy diet, staying active, avoiding smoking, and limiting alcohol intake. If you have concerns about symptoms or risk factors, speak with your healthcare provider about the best prevention and screening strategies for you.

Recognizing the early signs of colorectal cancer and seeking medical attention when necessary can save lives. Stay informed, prioritize screenings, and take charge of your health to prevent and detect colorectal cancer early.
