When it comes to cancer, everyone is afraid of avoiding it, especially liver cancer, which is more horrible than other malignant tumors because of its extremely high mortality rate and rapid development. After most patients know they have liver cancer, their first thought is to know how long they can live. There is a common saying that “”three months for the fast ones and six months for the slow ones”. So far, there is no definite answer to this question, and it is not something that can be predicted casually. It is mainly related to the type of liver cancer, the stage of liver cancer, the scope of metastasis, the patient’s physical and mental state, the treatment means and other aspects: 1. Primary liver cancer can be divided into hepatocellular liver cancer, cholangiocellular liver cancer and mixed liver cancer according to cellular typing. According to the morphology of tumor, it can be divided into nodular type, giant type and diffuse type. The symptoms of different types of lung cancer are different, and the degree of erosion to the body will be different, so the survival period of different types of patients will be different. 2.Related to the stage of liver cancer Liver cancer can be divided into early stage liver cancer, middle stage liver cancer and late stage liver cancer. Early stage liver cancer can be cured if it is detected early and treated timely, and the survival period is not much different from normal people. However, if scientific treatment is adopted, the quality of survival can be improved and the survival period can be prolonged. 3.Related to the metastasis and spread of liver cancer The main ways of liver cancer spread and metastasis are hematogenous metastasis, lymphatic metastasis and implantation metastasis. Different metastasis pathways and different metastatic sites will lead to different metastatic symptoms and degree of erosion to the body. Some patients do not have metastasis and spread of liver cancer, and they will recover better from treatment and have longer survival period. While some patients will have metastasis and spread of different degrees and scopes. If liver cancer once spreads to important parts, it will seriously threaten the life safety of lung cancer patients. 4.Related to the patient’s physical condition How long the patient can live is also related to the patient’s physical condition. Some liver cancer patients have poor physical quality, especially they have other diseases; while some patients have good physical quality and strong immune system, even after surgery or chemotherapy, they can recover to the best condition quickly, so the survival period will be longer. In addition, some liver cancer patients are in poor mental state and depressed for a long time because of the disease, which leads to endocrine disorder and immunity decline, further accelerating the development of cancer cells and shortening the survival cycle. In addition, special attention should be paid to diet, pay more attention to nutrition, give high protein, high calorie, high vitamin and low fat food to enhance patients’ physical fitness, which is also the key to determine patients’ survival period.
