1. Colon cancer liver metastasis:

Colon cancer on the left is often complicated by intestinal obstruction, sometimes with abdominal cramps, accompanied by abdominal distension and hyperactive bowel sounds. Patients with advanced liver metastasis of colon cancer often have varying degrees of abdominal pain, often with erosion, necrosis, and secondary infections. If it occurs on the right side, it will cause dull right abdominal pain, and sometimes post-prandial abdominal pain. In the late stage of liver metastasis of colon cancer, abdominal masses are more common in the right abdomen, suggesting that it has reached the middle and advanced stages. The surface of the masses may have a nodular sensation, which can generally be promoted, but it is fixed when the tumor is advanced, and there may be tenderness when the infection is combined. Patients with advanced liver metastases from colon cancer may develop progressive anemia, low fever, progressive wasting, cachexia, hepatomegaly, edema, jaundice, and ascites.
