D19: Benign neoplasm of mesothelial tissue

Benign neoplasm of mesothelial tissue describes a condition where non-cancerous tumors grow in the mesothelial tissue, which lines certain organs such as the lungs, heart, and abdominal organs. This kind of growth typically doesn't spread to other tissues or organs and generally remains localized. While the cells in this tumor can grow rapidly, they resemble normal cells and perform their functions properly. The prime cause behind these benign growths is often unknown. Symptoms for benign neoplasm of mesothelial tissue are variable and depend mainly on the organ the neoplasm is connected to. They may exist without causing any symptoms, but if the tumor grows large, it can press against surrounding organs and cause discomfort or other problems. Progression of this condition is slow and generally less aggressive than malignant or cancerous growths.
