What is Benign Mesothelioma?

While the majority of mesothelioma diagnoses are malignant, meaning cancerous, it is possible for benign tumors to form in the mesothelium. Unlike, malignant mesothelioma these benign tumors are typically removed through surgery and do not require additional treatments. Benign tumors are not capable of metastasizing or spreading to other organ systems. However, it is important for patients to recognize the distinction, as malignant mesothelioma is a very serious, rapidly progressing cancer with a 4 to 18 month survival rate following diagnosis.
