Breast cancer is the most prevalent Iranian female malignancy. Breast screening reduces the number of malignant breast diseases. We aimed to assess the results of the pilot breast cancer screening on early detection in female medical staff in Milad Hospital, Tehran, Iran. A cross-sectional study. Female medical staff from Milad Hospital, Tehran, Iran, were examined by a specialist in 2016. A checklist, including demographic data, was completed by the participants. If necessary, they referred to as sonography or mammography. Data were analyzed using SPSS software. Of 746 people enrolled, 137 had no pathological point, 609 had suspicious or positive findings that were referred for further investigation, 449 had normal findings, and 7 had suspicious mass and were biopsied, 6 were benign. One case had primary invasive cancer. Since screening for breast cancer helps to early detection of this disease, the implementation of cancer screening programs should be on the priority of health authorities.

Localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. Despite development of many techniques including angiography, MRI, sonography ,and frame base stereotaxy , a more accurate localizing technique is still needed (1,2) . A step forward to achieve this goal is to develop a navigation system. In this manuscript, we explained some clinical applications, advantages, and disadvantages of navigation system and tried to have a short glimpse on its future.
