Context: In the present study, we aimed to design a comprehensive system for screening, diagnosing, and treating breast cancer in the armed forces. Methods: We conducted a focused group meeting (FGM) and article review to evaluate one-stop clinics. Review studies with a standard design based on the PRISMA guidelines and the “Cochrane Handbook” to conduct data analysis were reviewed in the article review phase. In addition, for data extraction in the initial phase, the text of each session with specialists was read and discussed to get the general atmosphere of the meetings. Results: In the present study, we observed the importance of better diagnosis and treatment of army cases, as mentioned in previous studies. Thus, we should use one-stop clinics to screen, diagnose, and treat army cases with breast cancer. In the present study, we designed this system and reviewed the best results in screening, diagnosis, and treatment of breast cancer in army cases. Conclusions: A general and regular one-stop clinic dedicated to rapid diagnosis in a comprehensive cancer center can be a highly effective model of care, although not directly linked to screening structures.
