Why do you get liver cancer? What are the symptoms?

Now it is found that the causes of liver cancer include: 1, hepatitis B and hepatitis B virus carriers. 2. At present, it is reported abroad that about 13.2% of hepatitis C develops into liver cancer, which is twice that of hepatitis B, followed by cirrhosis. 4. Some chemicals such as nitrosamines, nitrogen mustard, alcohol and organochlorine pesticides are suspected carcinogens. Liver cancer is based on the principle of "early detection and early operation". Because liver cancer is not easy to have symptoms and cancer is not easy to be found, daily self-examination is very important. Epidemiological statistics show that the risk factors leading to liver cancer mainly include the following aspects: 1, hepatitis B or hepatitis C virus infection. 2. Aflatoxin. 3, drinking sewage or pond water containing a large number of organochlorine compounds and algae toxins. 4. Other factors such as ① family aggregation; ② Low selenium; ③ Alcoholic and nutritional cirrhosis. Symptomatic liver cancer has the characteristics of hidden onset, long incubation period, high malignancy, rapid progress, strong invasion, easy metastasis and poor prognosis. Its incidence rate is increasing year by year. Liver cancer belongs to the categories of accumulation, abdominal mass, jaundice, abdominal distension and hypochondriac pain in traditional Chinese medicine. Liver cancer is based on the principle of "early detection and early operation". Because liver cancer is not easy to have symptoms and cancer is not easy to be found, daily self-examination is very important. The early symptoms of liver cancer are not obvious, and even after a long period of illness, there is no feeling. When the disease develops to a certain extent, it will gradually produce some symptoms such as liver pain, loss of appetite, fatigue and thinness. Finally, there will be jaundice, ascites, hematemesis, coma and other manifestations. Huge swelling can often be felt in the upper abdomen of patients with liver cancer, but it has reached the middle and late stage and even metastasized to the lungs. Clinical symptoms of liver cancer digestive tract symptoms loss of appetite, epigastric fullness 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, with a high incidence and is easily 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. A considerable number of patients with liver cancer will sweat and have fever. Fever is mostly moderate to low fever, and a few patients may have high fever, which is above 39℃ and is generally not accompanied by chills. The fever of liver cancer is mostly cancerous fever, which is caused by the release of pyrogen into the blood circulation after tumor tissue necrosis. Cancer patients are prone to infection and fever because of their low resistance, which is sometimes difficult to distinguish from cancerous fever of liver cancer. It is necessary to combine the blood picture to observe whether the antibacterial treatment is effective. Patients with emaciation and fatigue liver cancer often feel more tired than other tumor patients, which is similar to patients with chronic hepatitis. The cause of fatigue is unknown, which may be due to digestive dysfunction and nutrient absorption disorder, or liver cells are damaged, liver function declines, so that metabolic disorder and some toxins cannot be inactivated in time, or liver cancer tissue necrosis releases toxic substances. Emaciation is also a common symptom in patients with liver cancer, which is due to impaired liver function. Digestion and absorption function decreased. With the development of the disease, the degree of emaciation can be aggravated, and cachexia appears in severe cases. Patients with lower extremity edema, liver cancer with ascites often have lower extremity edema, which occurs in the ankle and can spread to the whole lower extremity in severe cases. Clinically, I have seen some patients with high edema of lower limbs, and the skin of thighs can ooze water. The main reason of edema of lower limbs is that ascites compresses the veins of lower limbs or blocks tumor thrombus and venous reflux. Mild edema can also be caused by low plasma albumin. Bleeding tendency Patients with liver cancer often have bleeding tendency such as gingival bleeding and subcutaneous ecchymosis, which are mainly caused by impaired liver function and abnormal coagulation function, especially patients with liver cancer complicated with cirrhosis. Gastrointestinal bleeding is common, mainly esophageal varices caused by portal hypertension. In fact, gastrointestinal bleeding is also the main cause of death in patients with liver cancer. If you have liver cancer, the patient will feel physically tired first. Even if the patient lies down, it can't eliminate fatigue. This kind of burnout and fatigue that can't be eliminated is a common symptom of common liver diseases. The heat energy generated by the food ingested by the human body will be absorbed by the intestine, and part of it will be transported to the liver, stored in the liver, and then transported to all cells in the whole body. If the liver is invaded by cancer cells, the fuel supply of the whole body will be reduced, leading to physical fatigue and fatigue due to insufficient heat energy. If you are just tired or lazy, you may have a cold or be overtired. Few people realize that they may have liver cancer, so their illness has been dragging on. If the cancer tissue is slightly larger, it can cause dull pain in the heart socket or dull pain in the right upper abdomen. Even if it doesn't hurt, there will be oppression and discomfort. When suffering from liver cancer, symptoms caused by gastrointestinal disorders often appear, including loss of appetite, nausea, fullness after meals, stomach discomfort and so on. If you lose weight and sometimes have fever and jaundice of unknown reasons, you must go to the hospital for AFP, B-ultrasound, CT, X-ray hepatic angiography and other methods for diagnosis. The initial symptoms of liver cancer include abdominal distension, abdominal pain, general weakness, loss of appetite, jaundice and itchy skin.
