Benign (definition of)
In oncology, a benign tumor is one that does not grow nor spread to adjacent tissues, nor does it metastasize. Common types of benign tumors include moles and freckles.
Most benign tumors are non-life threatening. Nonetheless, some of these can cause health problems, such as compression of vital organs or blood vessels if left untreated. In addition, many benign tumors have the potential to become malignant.
Benign mesothelioma is described by oncologists as a "solitary fibrous tumor," located on the pleural or peritoneal lining. These are extremely rare, accounting for under 10% of all diagnosed cases. Symptoms are almost identical to malignant mesothelioma, and include:
- chest pain
- shortness of breath
- chronic cough
- clubbed fingers
In fact, it is virtually impossible to distinguish between benign and malignant mesothelioma without resorting to mesothelioma surgery.
The good news is that unlike the malignant form, benign mesothelioma is easily treated, and prognosis for the patient is usually excellent. However, benign mesothelioma can be a harbinger of a more serious condition developing in the future, so anyone who has had a benign case should receive regular checkups. Malignant mesothelioma (like peritoneal mesothelioma and pericardial mesothelioma) is potentially far more deadly, but may be treatable if caught in stage 1 and stage 2.
