National Health Commission: Scientific Approach to Radiation Issues in Tumor Imaging Examinations.

The National Health Commission held a press conference today to introduce health knowledge related to cancer prevention and early screening. Dr. Han Baohui, director of the Department of Respiratory Medicine at Shanghai Chest Hospital, mentioned that when it comes to lung cancer screening, many people are most concerned about the radiation exposure from the tests. This can be seen from three aspects: "why use low-dose spiral CT, how much radiation dose is given, is it worthwhile to do so".
