In the past, people always thought that having cancer was the same as having an incurable disease. Some patients, once diagnosed with cancer, immediately suffer from mental breakdown, depression, loss of confidence in life, and even irritability, irritability, suicide and other excessive behaviors. Their family members are also often overwhelmed by the diagnosis of cancer and have doubts about the treatment measures, or even give up the treatment. This makes some cancer patients who could have been treated lose the chance to be treated. Some doctors lack professional knowledge and do not know enough about the comprehensive treatment of cancer, and emphasize the role of certain treatment in a partial way, so that patients fail to receive comprehensive treatment in the real sense. In fact, quite a number of cancers can be treated or even cured. In recent years, due to the rapid development of medical science and the application of some high-tech methods, new treatment measures have been introduced, especially the emergence of gene therapy and molecular targeted therapy, which enable some originally untreatable cancer patients to receive effective treatment or live with tumor for a long time. The treatment of cancer is local and systemic. Local treatment is surgery first, and interventional treatment and radiation therapy can be adopted if surgery is not possible. Systemic treatment is mainly chemotherapy and traditional Chinese medicine. Gene therapy and molecular targeted therapy are also available. Once a cancer patient is diagnosed, the treatment should be based on the type, size, location, nature and malignancy of the cancer as well as the patient’s physical condition. A personalized treatment plan should be formulated and a patient electronic file should be established. Strictly follow the program in a sequential manner. Do not choose a single treatment blindly or interrupt the treatment at will. For cancer patients in the process of treatment, the efficacy evaluation should be conducted regularly and the treatment plan should be adjusted according to the efficacy. At the same time, patients and their family members are required to actively cooperate, so that patients can receive timely and effective treatment. Cancer patients should adjust their mentality and treat the disease correctly. They should establish confidence in curing cancer, go to regular hospitals or specialized departments and actively cooperate with the treatment. Once the spirit collapses, no treatment can help”. The necessary life conditioning should be carried out according to different cancers to keep the internal environment of the body relatively stable, increase the immunity of the body, and inhibit the growth of cancer cells. Thus, other treatment measures can play a better role and finally achieve clinical cure of cancer.
