World Health Organization (WHO) Classification of Tumors

The World Health Organization (WHO) Classification of Tumors is a global system used by doctors and scientists to categorize and describe different types of cancers and abnormal growths. It helps ensure consistent diagnosis and understanding of tumors by grouping them based on their appearance, behavior, and genetic features. This classification guides treatment decisions and research, ultimately aiming to improve patient outcomes. It covers many types of tumors from various organs and is regularly updated as new scientific knowledge emerges.
