The main symptoms of early colorectal cancer are blood in the stool and changes in bowel habits. When the cancer is confined to the rectal mucosa, blood in the stool is the only symptom of early colorectal cancer in 85% of cases. Unfortunately, patients often do not pay attention to it. During the rectal examination, a mass can often be felt. In addition to the common systemic symptoms such as loss of appetite, weight loss, and anemia, patients with mid- and late-stage colorectal cancer also have symptoms of local irritation of the cancer, such as increased bowel movements, incomplete bowel movements, frequent bowel movements, and tenesmus. The enlargement of the cancer can cause narrowing of the intestinal cavity and signs of intestinal obstruction.

In the late stage, colorectal cancer often invades surrounding tissues and organs, such as the bladder and prostate, causing frequent urination, urgency and difficulty urinating. It also invades the presacral nerve plexus, causing sacral and lumbar pain. Rectal cancer can also metastasize to the liver, causing liver enlargement, ascites, jaundice, and even cachexia and other symptoms of colorectal cancer.
