Fatigue
Just like other types of cancer, colon cancer makes your body extremely fatigued and exhausted. Increasing activities of cancerous cells force the immune system to work harder to fight against them. As a result, your level of energy would drop quickly in a short amount of time. You might feel weak and deeply tired during the day. This affects daily tasks at work or study. The symptom will not disappear until you seek proper treatments to inhibit the effects of tumors or cancerous cells in your digestive system. [2]
