Lung biopsy is the gold standard test for<unk>  of lung mass. However, in order to determine the extent of lung mass and to derive therapy other tests such as CT scan, sputum cytology and PET scan are also necessary. According to the American Joint Committee on Cancer (AJCC) staging system, there are 4 stages of malignant lung mass, based on 3 factors: tumor size, lymph node invasion, and metastasis. Each stage is assigned a letter and a number  that designate T for tumor size, N for node invasion, and M for metastasis.
