Diffuse liver ca refers to diffuse liver cancer. Diffuse hepatocellular carcinoma is a pathological type of primary hepatocellular carcinoma, also known as infiltrative hepatocellular carcinoma. The patient’s hepatocellular malignancy is diffuse, with a large number of cancerous nodules on the liver and multiple cancerous lesions in the liver. This type of lesion is more serious and has poor prognosis. 1. Clinical manifestations: patients with diffuse hepatocellular carcinoma usually have no symptoms in the early stage; when the lesion starts to progress, patients may have symptoms such as yellow staining of the sclera, pain in the liver area, fatigue, loss of appetite and so on, and ascites will be formed in patients with progressive stage. In addition, diffuse hepatocellular carcinoma can easily metastasize to other organs and show corresponding metastatic tumor symptoms. 2. Examination: the disease can be examined by ultrasound, CT, nuclear scan and other imaging means. In addition, blood test shows that the patient’s AFP (alpha-fetoprotein) value is constantly elevated, which is also of diagnostic value for this disease. For patients diagnosed with diffuse hepatocellular carcinoma, they should immediately go to the relevant departments of regular hospitals for treatment under the guidance of specialized physicians, so as to improve the quality of survival and prolong the survival period as much as possible.
