Nowadays, many tumor patients will choose traditional Chinese medicine treatment, but they have great doubts about the medication time and how long to change the prescription. Some patients do not come to see the doctor after taking Chinese medicine for a few days, thinking that they can stop seeing the doctor if they have no symptoms, which is a big mistake. This is a mistake. Tumor is not like a cold, which can be cured after taking a few doses of medicine, but requires a long time of medication. How long does it take? How often is it good to adjust the prescription? At present, there is no definite figure. Most of the old Chinese medicine practitioners believe that those who do not have tumor lesions should take one dose of medicine every day for the first two years, one dose every other day for the third year, one dose for three days for the fourth year, and one dose every week for the fifth year, so that the effect will be better. In an interview with a lymphoma patient in Beijing who had been taking Chinese medicine for a long time, I learned that during the five years of treatment, the prescription was adjusted quite frequently in the first year, usually once a week. After the third year, the patient’s condition stabilized, and the prescriptions were adjusted once every two weeks to once a month. Clinical observation shows that the recurrence and metastasis rates are significantly lower when taking Chinese medicine for a long time. The reduction of tumor recurrence and metastasis is not only a matter of tumor suppression, but also a matter of changing the constitution of tumor patients. If patients have tumor lesions, they should insist on long-term medication until the tumor disappears for 2 years before stopping the medication. But this is only if the doctor who prescribes the medicine to the patient really treats the patient with evidence and prescribes the right medicine. If a TCM doctor gives the wrong prescription to a patient and the patient still insists on not stopping the medicine, it is tantamount to killing oneself in disguise. Some patients will surely ask, how long is it reasonable to change prescriptions? It is generally believed that if you are seriously ill, you should change your prescription every day for a maximum of 7 days, or 2 weeks if you are more stable; for foreign patients, you should change your prescription once a month for a maximum of 2 months, why? Chinese medicine believes that about 2 months a main gas, each main gas treatment are different, treatment drugs need to change, so it is best to see the doctor often. But still, the key is to find a really responsible and qualified TCM practitioner, otherwise even if you change every day, there is still no benefit for your body. For tumor patients, it is recommended that when looking for Chinese medicine to treat their diseases, they should not seek treatment for their diseases. You must be cautious and objective in looking at TCM, and do not blindly believe in the TCM doctor you want to see when you are not sure whether he has the real medical skills and level. Only when you are sure that the TCM doctor himself has the legal qualification to practice medicine, the ability to dialectically prescribe, and the trustworthy character, you can be assured that you will be able to see him. In addition, TCM treatment is aimed at self-adjustment of the human body, through the use of medicine to restore the body’s own functions to ensure the healthy operation of the five organs and six bowels. To sum up, there are two keys for tumor patients to grasp such a problem as how long to take Chinese medicine, the first one is to find the right TCM doctor: one who is legally qualified to practice medicine, with real level and trustworthy character. The second is to always pay attention to your physical condition. Chinese medicine treatment is through the use of Chinese medicine and with the coordination mechanism of the self body, the patient’s own physical condition is most clear to himself.
