Colon cancer often starts silently but reveals warning signs like rectal bleeding, changes in bowel habits, abdominal pain, and unexplained weight loss. Early detection can save lives. Dr. Nitin Jha, an expert in advanced gastrointestinal surgery, explains the key symptoms of colon cancer you should never ignore.
Signs and Symptoms of Colon Cancer
By Dr. Nitin Jha, Senior Laparoscopic and Robotic Surgeon
Colon cancer, also known as colorectal cancer, is one of the leading causes of cancer-related deaths worldwide. It often begins as benign polyps in the colon or rectum that may turn cancerous over time. The good news is that colon cancer is highly treatable if caught early. That’s why recognizing its signs and symptoms is crucial for timely diagnosis and treatment.
1. Persistent Diarrhea or Constipation
Changes in bowel habits are one of the earliest signs of colon cancer. If you experience persistent diarrhea or constipation that lasts for more than a few days, it could be a red flag.
- Diarrhea may indicate irritation or a partial blockage in the colon.
- Constipation could suggest a growing tumor causing obstruction.
These changes are often ignored or attributed to diet or stress, but chronic irregularities warrant a medical consultation.
2. Rectal Bleeding or Blood in the Stool
One of the hallmark symptoms of colon cancer is rectal bleeding or blood-streaked stool. While hemorrhoids or fissures can also cause bleeding, colon cancer-related bleeding is usually darker or mixed with stool.
- Bright red blood may signal bleeding near the rectum.
- Dark or tarry stools could indicate bleeding higher up in the colon.
If you notice this symptom, do not delay in getting a colonoscopy or appropriate diagnostic test.
3. Abdominal Pain, Cramps, or Bloating
As the tumor grows, it can interfere with the normal function of the colon, causing discomfort or pain in the abdomen. Patients often report:
- Cramping or dull pain that doesn’t go away
- Bloating or a feeling of fullness even after eating small amounts
- Sharp abdominal pain, especially if there’s a blockage
If these symptoms persist or become more intense over time, they should be investigated without delay.
4. Unexplained Weight Loss
Weight loss without a clear cause is always concerning and is a common symptom of many types of cancer, including colon cancer.
- If you’re losing weight despite no changes in diet or physical activity,
- Or if your appetite has decreased significantly,
… it’s essential to consider cancer screening as part of your medical evaluation.
This symptom usually appears in the later stages of colon cancer, but in some cases, it can be an early clue, especially when combined with other symptoms.
5. Weakness and Fatigue
Cancer cells consume the body’s energy and nutrients, which can lead to persistent tiredness and weakness. Additionally, chronic blood loss from the tumor can cause anemia, resulting in:
- Shortness of breath
- Pale skin
- Difficulty in concentration
- General fatigue even after resting
If you feel unusually weak and notice other digestive symptoms, it could be more than just lifestyle-related tiredness.
When Should You See a Doctor?
If you’re experiencing one or more of these symptoms, especially for more than a couple of weeks, it’s time to consult a specialist. While these symptoms can have other causes, ruling out colon cancer is critical to ensure early intervention.
Risk Factors to Watch For:
- Age over 50 (although younger people can also develop it)
- Family history of colon cancer or polyps
- Sedentary lifestyle
- Low-fiber, high-fat diet
- Smoking and heavy alcohol use
- History of inflammatory bowel disease (Crohn’s or Ulcerative Colitis)
Early Detection Saves Lives
The survival rate for colon cancer significantly improves with early detection. Colonoscopy remains the gold standard for screening and can also allow for polyp removal before they become cancerous.
