WHO (World Health Organization) classification of lymphoid neoplasms

The WHO classification of lymphoid neoplasms organizes blood cancers that originate from lymphocytes (a type of immune cell) into specific categories based on their characteristics, origin, and behavior. It provides a standardized way for doctors worldwide to diagnose, study, and treat these cancers. This system considers factors like cell type (B-cell or T-cell), genetic features, and how aggressive the disease is. By classifying lymphoid neoplasms accurately, clinicians can determine the best treatment approach and predict how the disease might progress.
