Papillary Mesothelioma is a subtype of epithelial mesothelioma—a condition where the membranes within the body are invaded by cube-like cancer cells. These cancer cells may form into a tumor or tumors, referred to as well-differentiated papillary mesothelioma (this mesothelioma is commonly referred to as “WDPM”).
Symptoms of papillary mesothelioma may include pain and excessive fluid buildup in the membranes or body cavities of patients. However, in most cases, patients will be asymptomatic. Papillary mesothelioma is also very slow-moving. The cells multiply at a very low rate, do not often infect other tissues, and in some cases, are totally inactive. Experts may refer to these tumors as “low grade” (as opposed to high grade). WDPM in one location has generally been linked to a slower, non-malignant growth, but if it appears in several places throughout the body, it is likely to indicate a more aggressive and dangerous form of cancer.
