The survival rate for mesothelioma in stage I is 21 months, stage II is 19 months, stage III is 16 months and stage IV is 12 months, according to the American Cancer Society. It is important to note that survival rates are based on median survival.
The American Cancer Society reports that survival rates are based on various factors and only rough estimates at best. Patients age and overall health, as well as whether the cancer is operable, affect the overall survival outlook. Improvements in health care and cancer treatments are also notable because survival rates must be taken from previous years.
