There is a famous saying in Chinese medicine that the effect is not correct. Since it is effective, don't change the prescription casually. What you did was right. The dosage and prescription haven't changed for two years, just make appropriate drug adjustment according to the change of symptoms, and stick to it in the future. This is the treatment of treating both the symptoms and the root causes. Drugs that can cure diseases, if tested to be effective, should not be changed easily, so as to complete the process from quantitative change to qualitative change and achieve the effect of recovery.

The above is just a general statement. I don't know what cancer you have, and I don't know whether the medicine you take contains toxic drugs. If it is a toxic Chinese medicine, it should be stopped immediately in clinical practice, and it can not be taken for a long time, which may lead to chronic accumulation poisoning.

Taking nourishing Chinese medicine, especially tonic Chinese medicine, is not suitable for taking radish at the same time, because radish has the function of promoting digestion and breaking qi. When taking nourishing Chinese medicine such as ginseng, eating radish will reduce the effect of tonic.
