Every disease has an onset process. For common liver cancer diseases, it should be found in the late stage, which has a great influence on treatment. So, how much is it? Take a closer look at our experts' introduction to this problem. According to experts, it takes about 2 years from the formation of the first cancer cell in the liver to the patient's self-conscious symptoms. During this period, patients may not have any symptoms or signs, only a few patients may have symptoms such as loss of appetite, flatulence in the upper abdomen, abdominal pain, fatigue, loss of appetite, and some patients may have mild hepatomegaly, jaundice, skin itching and other symptoms. But generally speaking, these symptoms are difficult to be taken seriously by people, so many patients with liver cancer are often found in the middle and late stages. Patients with advanced liver cancer cannot rely solely on surgery, chemotherapy and radiotherapy. Tumor biotherapy combined with other treatment methods not only improves the curative effect, but also significantly reduces the metastasis and recurrence rate. It is becoming a new model for the treatment of lung malignant tumor, which is highly valued by people in the industry. Biological therapy is to induce and expand patients' peripheral blood mononuclear cells into DC/CIK cells in GMP laboratory, and then transfuse them into patients to kill lung tumor cells and repair the immune function of the body. The curative effect is definite when used alone, and it is better when used in combination with surgery, radiotherapy and chemotherapy. Moreover, this method is very safe and has almost no toxic side effects. ? In fact, after everyone knows this problem, experts will introduce several early symptoms of liver cancer. I hope you can take precautions. 1. Symptoms of obvious loss of appetite: The most common symptom in the early stage of general liver cancer patients is the feeling of abdominal distension and discomfort. At the same time, patients will also have symptoms of loss of appetite and indigestion in the early stage, and the symptoms of nausea and vomiting in the early stage are not as serious as those in the later stage. 2. Symptoms of pain in the liver area: Generally, patients with liver cancer will not have severe symptoms of pain in the liver area in the early stage. Most patients' early pain symptoms are persistent and intermittent, and patients with liver cancer will aggravate the symptoms when changing their positions, so people must pay attention to the appearance of this symptom.
