Many friends will think that there is no way to receive treatment for cancer, and they can only wait for death slowly. In fact, this idea is wrong. Timely treatment is of great help to relieve the patient's condition. What is liver cancer? What are the early symptoms of liver cancer? Let's take a look at what liver cancer is. Early symptoms of liver cancer. Liver cancer is a malignant tumor that occurs in the liver and has a high mortality rate. Known as primary liver cancer, it is a malignant tumor of the liver formed by cancer transferring from other organs of the body to the liver. Known as secondary liver cancer, also known as metastatic liver cancer. The initial symptoms are not obvious, and the later symptoms are mainly pain, fatigue, emaciation, jaundice, ascites and so on. The first symptom of most patients with advanced liver cancer is pain in the liver area, and the incidence rate is above 50%. The pain in the liver area is generally located under the right rib or xiphoid process, and the pain is intermittent or persistent dull pain. Dull pain or tingling, the patient may feel discomfort in the right upper abdomen some time before the pain. The pain can be relieved by itself in a short time. The main cause of pain is the rapid enlargement of tumor, which compresses the liver capsule and produces traction pain. It can also be caused by tumor necrosis stimulating the liver capsule. A few patients spontaneously or suddenly have severe pain in the liver area after liver puncture, which is mostly caused by rupture and bleeding of cancer nodules on the surface of the liver. If there is blood pressure drop and shock at the same time, there is bloody liquid at the puncture site of abdominal cavity, which indicates that the cancer node is ruptured and bleeding seriously. In this case, emergency rescue is needed. Without the above-mentioned accompanying symptoms, the pain is limited, indicating that the bleeding is located under the liver capsule. The pain varies according to the location of the tumor growth. Tumors located in the left lobe often cause pain in the upper and middle abdomen. The tumor is located in the right lobe, and the pain is in the right quarter rib; When the tumor involves the diaphragm, the pain radiates to the right shoulder or back, which is easily mistaken for shoulder arthritis; When the tumor is located in the posterior segment of the right lobe, it can sometimes cause low back pain; Patients with tumors located in deep liver parenchyma generally do not feel pain. Symptoms of digestive tract, loss of appetite, fullness of upper abdomen after meals. Heating, dyspepsia and nausea are common digestive tract symptoms of liver cancer, among which loss of appetite and abdominal distension are the most common. Diarrhea is also a common digestive tract symptom of liver cancer, which has been reported at home and abroad. The incidence rate is high and it is easy to be mistaken for chronic enteritis. Portal hypertension and intestinal dysfunction caused by tumor thrombus in portal vein or hepatic vein can cause abdominal distension, increase stool frequency and ascites can also cause abdominal distension. Gastrointestinal dysfunction can also lead to indigestion, warm gas, nausea and other symptoms.
