At present, the most important thing for tumor treatment or prevention is to adjust the internal environment of the body, so that the internal environment of the body can reach a state close to equilibrium, which is good for preventing the recurrence and metastasis of tumor. I don’t agree with the method of prescribing a bunch of so-called anti-cancer Chinese medicines, such as the commonly used ones like white flowering snake’s tongue, half a lotus, half a lotus and so on. Firstly, those so-called anti-cancer herbs have not been proven to be effective, and secondly, even if they are effective, the use of these herbs without evidence will disrupt the balance of the body’s internal environment and promote tumor growth instead.
