summary

I believe some people will know that it takes two years for liver cancer to develop from the first cancer cell to patients with abdominal pain and other obvious symptoms. Early general symptoms are very few, but patients with advanced liver cancer are not only abdominal pain and abdominal distension, but also fatigue, weight loss and progressive hepatomegaly. In addition, patients with advanced liver cancer will have upper abdominal mass, and even patients with liver cancer will have symptoms of low fever. Once liver cancer ruptures, they will have acute abdomen. The patient will have symptoms, not obvious symptoms of metastasis.

The symptoms of liver cancer in B ultrasound

Capsule: for liver cancer with a diameter of less than 3cm, the capsule is usually complete and composed of fibrous tissue. Its acoustic impedance is higher than that of surrounding liver tissue and cancer. Therefore, it forms interface reflection. On the two-dimensional sonogram, it can be shown that a thin hypoechoic membrane surrounds the whole cancer node.

Early liver cancer patients, because of five obvious signs, and some early liver cancer patients even have symptoms and signs similar to cirrhosis, but some patients with advanced liver cancer are more painful, patients will have hepatomegaly symptoms, and patients will appear jaundice and ascites.

In fact, the symptoms of early liver cancer by B-ultrasound are very obvious, and we have known for a long time that early cancer not only has no obvious symptoms, but also can not be ruled out when doing B-ultrasound. Most patients with liver cancer are in the middle and advanced stage when they are diagnosed. It is suggested that high-risk people need B-ultrasound, and serum alpha fetoprotein, AFP, MRI and other examinations.

matters needing attention

Internal echo: the internal echo is different, and has a tendency to change. In addition to uniform low echo details, the echo of other cancer nodules is uneven distribution. The detection rate of liver cancer nodules less than one centimeter detected by ultrasound is 33% - 37%.
