Patients with early-stage liver cancer do not experience darkening of the facial complexion. This is because early-stage liver cancer primarily refers to carcinoma in situ of the liver and some small liver cancers. Since the tumors are small and the affected area is limited, they generally cause few symptoms clinically. Some patients may experience mild fatigue and a decrease in appetite, but these do not lead to changes in the complexion. Only when the liver cancer progresses to the middle or late stages, causing damage to liver cell functions or when the pathology metastasizes, leading to damage to multiple organ functions, can there be some changes in facial complexion. For example, patients may exhibit pale complexions due to moderate to severe anemia. Some patients may have yellowing of the skin due to obstructive jaundice or hepatocellular jaundice. Additionally, some patients may show darkening of the facial complexion due to abnormal hormone secretion.
