Colon cancer symptoms?

The main clinical features of early colorectal cancer are bloody stool and change of defecation habits. When the cancer is confined to the rectal mucosa, bloody stool is the only early symptom accounting for 85%. Unfortunately, it is often ignored by patients. In addition to the common systemic symptoms such as loss of appetite, weight loss and anemia, patients with advanced colorectal cancer also had local irritation symptoms such as increased frequency of defecation, incomplete defecation, frequent defecation and severe back pain. The enlargement of cancer may cause intestinal stenosis and obstruction.

In the late stage, cancer often invades surrounding tissues and organs, such as bladder and prostate, causing frequent urination, urgency and dysuria. Invasion of presacral plexus, sacrococcygeal and lumbar pain. Rectal cancer can also metastasize to the liver, causing hepatomegaly, ascites, jaundice, and even cachexia.
