Symptoms of COLORECTAL CANCER
The symptoms which appear increase as the tumor enlarges. At first, there may be minimal or no symptoms. As the tumor progresses, there is usually a change in the frequency, appearance, or size of the stool. In addition, blood in the stool or black stools may occur. People develop lower abdominal pain and swelling. Loss of weight and loss of appetite commonly occur. With increasing blood loss, people may feel fatigued or develop shortness of breath or rapid or irregular heart beats. If the tumor obstructs the intestinal tract, severe constipation, abdominal swelling, nausea, and vomiting will occur.
