  • The N Status - whether lymph nodes inside or outside the lung are involved

  • The M Status - whether there are other areas outside the chest (metastases) that have cancer

Mesothelioma is difficult to stage with X-rays and sometimes requires other tests, including:

The NYU Division of Thoracic Surgery is recognized as the Biomarker Discovery Laboratory by the National Cancer Institute. The NYU Thoracic Oncology Program's expert multidisciplinary staff treats all stages of mesothelioma.
