Theoretical analyses of gastric cancers lead us to point out seven important indications about carcinogenesis. First, in a human body, not the microscopic but the macroscopic mechanisms play an important role in causing cancer. Second, carcinogenesis in vivo differs in carcinogenic mechanism from that in vitro. Third, although the majority of medical researchers focus on examining the relationship between immunity and carcinogenesis, theoretical analyses of gastric cancers lead us to suggest that immunity aggressively permits an organ in a certain condition to cause cancer. Fourth, medical doctors, who treat a person suffering from gastric scirrhus, need to notice the existence of posterior force and to make a therapy of cutting it out. Fifth, helicobacter pylori can be considered to play a role in causing strong primary tissue distortion in the stomach wall. Sixth, the most important problem, which prevents us from finding out the fundamental cause of cancer, is in our mind. Seventh, modern medical science should establish a new field, theoretical medicine, in order to make a great progress.
(1) Microscopic and Macroscopic Mechanisms
Although the majority of medical researchers pay attention only to microscopic mechanisms in a human body such as chemical reactions, genetic functions and so on, they should notice that macroscopic mechanisms in a human body play a major role in causing cancer. In a human body, the microscopic mechanisms maintain the symmetrical relationship with the macroscopic mechanisms, and not only control but also are controlled by the macroscopic mechanisms. That is, a human body maintains the life both by using the microscopic and the macroscopic mechanisms. Thus, whenever medical researchers check any obscure mechanisms about disease including cancer, they should take notice of the relationship between microscopic and macroscopic mechanisms in a human body. Undoubtedly, paying attention to this relationship will allow medical researchers to notice new points of views toward disease, as well as help them find out the fundamental causes of diseases including cancer.
Additionally, modern medical science has divided a human body into many parts in order to analyze accurately the obscure mechanisms. Just this division forces medical researchers and doctors to narrow their view points, and to pay attention only to microscopic mechanisms. A human body, as explained before, is a relative system consisting of organs, each of which always balances itself with other organs. This balance works as the stability of a human body, and which allows a human body to maintain the life. These indications reveal that even when an organ appears to change its circumstance for itself, its fundamental cause always originates in the relationship between the organ and the other organs: the background organs. Thus, whenever medical researches try to check any obscure mechanism in a human body, they need to pay attention not only to the mechanism itself but also to the relationship between the microscopic and the macroscopic mechanisms in a human body.
(2) Difference between Carcinogenesis in Vivo and in Vitro
Carcinogenesis in vivo (tissular carcinogenesis) quite differs in carcinogenic mechanism from that in vitro (cellular carcinogenesis). Usually when medical researchers examine carcinogenesis, they often check it by using cultured cells. Certainly, this procedure enables medical researchers to find out various accurate mechanisms about carcinogenesis. However, even if they check carcinogenesis by using cultured cells, they will be unable to find out how a tissue causes cancer. Why? This is because tissular carcinogenesis quite differs in outbreak mechanism from cellular one. That is, even when medical researchers try to check tissular carcinogenesis only by using cultured cells, they will be unable to find out the fundamental mechanisms. Thus, whenever medical researchers examine carcinogenesis, they should take notice of the difference in carcinogenesis between vivo and vitro.
(3) Immunity and Carcinogenesis
Although the majority of medical researchers tend to think that immunity always plays a role in preventing a human body from causing diseases including cancer, they should also recheck this thought. When a human body loses good balance among the organs, it will often aggressively destroy its own cells to regain the good balance. In this process, a human body must, by using the immunity, destroy its own cells. Certainly, although a phenomenon: “immunity destroys cells” appears to be an abnormal one, it can theoretically be considered one of the normal phenomena seen in a human body. Likewise, although carcinogenesis appears to be one of the abnormal phenomena caused in a human body, it can also be considered one of the normal phenomena seen in a human body. That is, there is a strong possibility that immunity aggressively permits a tissue in a certain condition to cause carcinogenesis. Undoubtedly, unless medical researchers can understand such a special characteristic of immunity, they will be unable to control cancer completely even by using immune therapy.
