If you experience an unintentional loss of 5% or more of your weight within 6 months, then it’s a clear sign that something is terribly wrong. This happens because cancer cells use the energy of the body as fuel, which affects the immune system and causes weight loss.
Colon cancer patients often have a big tumor blocking the colon, thus bowel movements are disrupted and weight loss occurs.
Irregular bowel movements
The colon polyps can turn cancerous over time and affect your bowel movements. They can also influence your large intestine function and cause stool changes.
