American Registry of Pathology

The American Registry of Pathology (ARP) is an organization that collects and manages information about diseases, especially cancer, based on detailed laboratory examinations of tissue samples. It helps improve understanding of disease trends, supports research, and ensures high-quality diagnostic standards. By compiling data from pathology laboratories across the U.S., ARP aids scientists and healthcare providers in studying disease patterns, developing treatments, and advancing medical knowledge to improve patient care.
