After the occurrence and diagnosis of cancer, it is necessary to choose surgery to remove it. Generally, surgery is better for early stage 1 or stage 2 patients, and stage 3 or above patients are just barely operated. However, we often see many post-surgical patients have recurrence and metastasis after chemotherapy treatment in the clinic. This is because, the cancer masses removed by our surgery are visible and palpable, and some tiny lesions cannot be detected and removed. If, at this period, the immunity of human body is still OK, these tiny lesions may be suppressed by the immune system of human body and will not grow quickly. If, during this period, we carry out chemotherapy treatment in the hope of killing cancer cells completely, we may destroy the immune ability of the human body and lose the ability of the human body to fight against cancer, which will make these tiny cancers grow up quickly, and recurrence and metastasis will occur. Because the connection between the blood vessels of these tiny cancer cells and the blood vessels of human body is not smooth, chemotherapy drugs are delivered through the blood vessels, and most of the drugs cannot reach the cancer cells, instead, the normal tissue system is destroyed, and the normal immune function is weakened and cannot play the role of immunity, those tiny cancer cells will grow up, and it is difficult to treat the cancer cells at this time, and the result is that the more chemotherapy treatment is given, the worse the disease will be. The more chemotherapy is administered, the worse the result will be. Therefore, patients after surgery or radiotherapy must be treated with Chinese medicine, because the function of Chinese medicine is to adjust the human body’s environment, normalize the body’s weakened immune system, strengthen and improve the body’s weakened physiological functions, and through the recovery of the immune system, combined with non-toxic anti-cancer herbal medicine for anti-cancer treatment, cancer patients can improve their condition, so that they can survive without cancer or with tumor. The combination of anti-cancer treatment with non-toxic herbs with anti-cancer effects can make cancer patients’ condition improve, so that they can survive cancer-free or with tumor and maintain a good quality of survival. Clinically, it is often seen that patients who have undergone TCM treatment have a very obvious difference in their ability to live, status and control of their disease than those who have not undergone TCM treatment. Moreover, cancer is a special disease that is difficult to be effectively treated by doctors without clinical experience in oncology treatment, and sometimes it is counterproductive, so cancer patients should choose carefully.
