The Costwold System divides both HL and NHL into how many stages?

The Cotswold System classifies both Hodgkin Lymphoma (HL) and Non-Hodgkin Lymphoma (NHL) into four distinct stages. This staging system is instrumental for oncologists as it aids in determining the extent of the disease and helps guide treatment decisions.

In this classification, the stages are defined based on the number and location of affected lymph nodes, as well as the presence of systemic symptoms. By identifying four stages, the Cotswold System provides a more detailed framework compared to simpler systems, allowing healthcare providers to better describe the disease progression and tailor therapies accordingly.

This level of granularity is essential for effective patient management and plays a critical role in prognosis determination. Understanding the distinction between these stages is vital for both clinical practice and for students preparing for examinations related to oncology and radiology.
