Lung cancer is the most common cancer in the world, and could have devastating effects to one’s health if not caught early enough. In order to combat this, the implementation of low-dose computed tomography (LDCT) lung cancer screenings can be used to help detect the cancer early. Questionnaires are used in order to determine if people are high-risk for developing lung cancer and qualify for this scan. Physicians have been reported to believe in these screenings and feel they help improve survival rates and early diagnosis of lung cancer. Although there are many positives with LDCT, there are also some problems. The continued radiation dose is of concern along with how the radiation can also influence future developments of radiation induced lung cancer. Another problem with LDCT lung cancer screenings is the false positive rate on diagnosis of lung nodules, which has been high in some of the studies conducted on this topic. Although LDCT lung cancer screenings have had these problems, the future looks promising with the advancement of technology and more studies done on the topic.
