Losing weight without trying is a common symptom in most cancers, including colon cancer. When the body is fighting cancer, the immune system is constantly on overdrive, and tumors can affect digestion and appetite. If you notice significant weight loss without changes in diet or exercise, it is important to see a doctor. This symptom often appears later, but can sometimes be an early warning sign as well.
