The completion of the project trying to analyze the genome of human beings is said to be attained in 2001, if it is done early, and that even if it is done late, it will in 2003. Some go so far as to say, "One will be able to have the CD-ROM in which the information of one's own hereditary information is saved. Since they have not known the root causes of diseases, doctors have lumped one disease with others, and have had contacts with patients.For example, when it comes to cancer, what are said is only 'Anticancer drugs are convenient." or "Radiotherapy does well". They have never chosen any treatments with the criteria, whether the treatments fit patients. However, the completion of the project and the study made by it will enable us to recognize which gene distribution cause diseases, and to give medical treatments that fit to the gene distribution: colon cancer can not be defined as one type. It is possible that some colon cancer is caused by the disorder of the 1st and the 150th gene distribution and other by the disorder of the 2nd and the 400th. seen from the interpretation of the interior of the body, cancer of infinite types are recognized. Scrutinization of the role of each gene will enable us to do medical treatment for the sake of each person, namely "Ordermade Medical Treatment". A judgement such as "This medicine will do" or "That therapy does better" can be done thanks to the analysies about gene distributions.
Later on, strategy to establish such medical treatment needs constructing. After the scrutinization, study for the good of patients should be done, when molecular biology, information genetics and so on, which we have used are required, in, the meantime, not only diseases but also the characters and behavior of one will be able to be related to genes, This can be a new problem concerning one's privacy in the near future. It is necessary that we consider how to protect such private gene information and do write down on paper.
