Liver cancer is one of the common malignant tumors in the digestive system. In the early stages of liver cancer, most patients do not exhibit symptoms of skin itching. It is only when the cancer progresses and causes obstructive jaundice that patients clinically develop symptoms of skin itching. Early-stage liver cancer patients typically do not show typical clinical symptoms, or they may not have any significant symptoms at all. This is because early-stage liver cancer lesions are small and localized, without external invasion or metastasis. Therefore, the impact on the entire body is minimal, and clinically it generally manifests as mild abdominal bloating, discomfort, nausea, diarrhea, and some patients may experience a dull ache or discomfort in the liver area. Because the symptoms of early-stage liver cancer are atypical, many patients are already in the middle to late stages by the time they seek medical attention, missing the opportunity for clinical cure.
