Adhere to lamivudine tablets to control hepatitis B virus, one tablet daily without interruption. Give hepatic artery cannulation chemoembolization (referred to as TACE) to destroy potential microscopic cancer cells. Regular review, including blood tests and liver ultrasound. The patient was strictly followed. Recent follow-up revealed that the patient was free of discomfort, with good control of hepatitis B virus, and no signs of cancer recurrence or metastasis were detected. According to the information provided by the patient’s family, some of the patients who had surgery at the same time did not insist on taking traditional Chinese medicine and some did not change their past bad habits, as a result, the cancer cells recurred in a short period of time. Curing a disease is like fighting a war, and cancer cells are like enemies. Surgery has cut off the visible cancer mass, and the remaining invisible cancer cells are very few in number, just like stragglers. If we are negligent and do not treat the cancer cells after surgery, it will be difficult to treat the cancer cells after they have formed again or metastasized, and it will be difficult to cure them. Cancer cells are not ordinary enemies, but special forces among enemies with strong vitality, which are difficult to be completely driven out and killed, so comprehensive measures must be taken. Combination of Chinese medicine and Western medicine, combination of pharmacotherapy and food therapy, combination of local treatment and systemic treatment, psychological adjustment, exercise and daily living should be used, that is, all 18 weapons should be used to interfere with cancer cells in all aspects, multiple ways and multiple levels to make it difficult for them to develop. We cannot be afraid of trouble and use only one or two of these methods or measures, which will reduce the probability of overcoming cancer cells.
