Scientists now believe that precision medicine, which employs complicated technology and information derived from omics, can treat complex diseases and provide justice in health. Implementation of precision medicine will face new ethical challenges, considering the principles of medical ethics. With respect to philosophical principles, this study addressed the issue of justice and some ethical challenges of precision medicine. Because, in order to gain the benefits of precision medicine, a proper ethical framework must be developed while considering the challenges. The manner in which precision medicine information is shared and accessed can have an impact on people’s future careers, marriage choices, and type of health insurance. Furthermore, preserving people’s privacy and autonomy are important ethical concerns in precision medicine since there will be no perfect guarantee about data security and access. Although in the short and medium term, due to the design of studies and expensive and complex technologies, precision medicine will be limited to certain groups and will intensify the inequality in justice, in the long run, with the easy access and inexpensive cost of precision medicine technologies, the accumulation of medical expenses will decrease throughout life, and justice will be established between and within countries.
