General abdominal discomfort such as frequent gas pains, bloating, fullness or cramps can also be felt by a person that has developed colon cancer.


In general, weakness and discomfort will be felt, but constant tiredness and a lose of weight can also be symptoms of colon cancer, because when the cancer affects the colon and they why the organ functions, the whole body is going to feel it, as said. If colon cancer evolves and reaches stage four before it is diagnosed, other symptoms may occur depending on the location of the metastatic tumor.
