The chest film is one of the most common methods of detecting lung cancer, which often appears as solitary nodules or hilar masses. Once the diagnosis is established, the most effective treatment can be determined and staging of the tumor can be done. Surgical resection is the only cure for non-small-cell carcinoma, although radiotherapy and chemotherapy may shrink some tumors. Because 90% of all cases are caused by smoking, a preventive approach to the disease is crucial. Screening of high-risk patients (ie, smokers with airflow obstruction) using chest films and sputum cytology may aid this approach.
胸部X光片是检测肺癌最常用的方法之一，肺癌在胸片上常表现为孤立性结节或肺门肿块。一旦确诊，就可以确定最有效的治疗方法并对肿瘤进行分期。手术切除是治疗非小细胞肺癌的唯一治愈方法，尽管放疗和化疗可能会使一些肿瘤缩小。由于所有病例中有90%是由吸烟引起的，因此对该疾病采取预防措施至关重要。使用胸部X光片和痰细胞学检查对高危患者（即有气流阻塞的吸烟者）进行筛查可能有助于采取这种预防措施。
