Unusual Signs of Colon Cancer That You Shouldn’t Ignore

4. Fatigue and Weakness

Feeling unusually tired, even after adequate rest, can be linked to colon cancer. Tumors in the colon may cause internal bleeding, leading to anemia (low red blood cell count). This reduces the body’s ability to carry oxygen, resulting in persistent fatigue and weakness that doesn’t improve with rest.

5. Unexplained Weight Loss

While weight loss can be a symptom of many illnesses, losing weight without diet or exercise changes should raise concerns. Colon cancer may cause metabolic changes that burn more energy, or tumors may interfere with the body’s ability to absorb nutrients properly.

6. Blood in the Stool (Often Overlooked)

Blood in the stool is one of the most prevalent, yet sometimes disregarded, signs of colon cancer. Some people dismiss it as hemorrhoids or minor digestive irritation, but chronic or recurrent bleeding should always be taken seriously. Dark or tarry stools may indicate internal bleeding higher in the colon, even if the blood is not brilliant red.

7. Feeling of Incomplete Bowel Movements

Even after using the restroom, colon cancer might cause the feeling that the intestine has not yet emptied fully. This occurs because a tumor obstructs part of the colon, causing irritation and incomplete evacuation. If this symptom persists, it should not be ignored.

8. Nausea and Vomiting

When colon cancer causes significant blockages, it can lead to digestive backups, resulting in nausea and sometimes vomiting. This is more common in advanced stages, but it can occasionally appear earlier, especially if the tumor interferes with normal digestion.
