Since entering the 21st century, with the development of economy and the increase of health consciousness concern, the understanding of tumor has been deepened. Although the research on the pathogenesis of tumors is becoming clearer and clearer, and the means of tumor treatment is becoming more and more abundant, so far there is no proven method for tumor intervention. Although there are many means for patients in front of tumors, medical practitioners who are crowned with high expectation of saving lives and helping the sick are always trying to help patients overcome the disease with a professional, native and professional compassion. Although, the methods provided are not lack of palliative. Although tumor, as a difficult disease, still becomes a difficult problem for medical practitioners all over the world to pay attention to and study, and there is still no key secret of its pathogenesis unlocked. However, on the road of research, especially in the rich practice of clinical prevention and treatment, an interesting phenomenon has been gradually explored: living with tumor and making peace with tumor. The so-called survival with tumor means that the tumor cells do not have to be killed in full (although full killing is difficult to achieve), but by adjusting the immune status, so that the body, in the presence of the tumor, the tumor cells grow slowly or stop growing, while living peacefully with the normal cells of the body for a long time. It can be said that “survival with tumor” is a helpless phenomenon in tumor research and treatment, but it is this helpless concept that has brought gospel to many tumor patients in clinical practice. As long as one has a good attitude, a healthy lifestyle, a positive and scientific intervention and treatment, and through the combination of appropriate anti-cancer therapy and comprehensive therapies such as regulating immunity and helping to dispel evil, as well as abandoning unscientific and superstitious non-scientific means, the life of tumor patients can be continuously extended and even gradually enter the path of recovery.
