How is Non-Hodgkin Lymphoma Diagnosed?
Published: May 10, 2024
Diagnosing non-Hodgkin lymphoma involves a series of tests to accurately identify the type and stage. Knowing the diagnosis process can help demystify what to expect.
Initial Steps in Diagnosis
The first step in diagnosing NHL is a thorough physical examination and medical history review. Doctors will check for swollen lymph nodes and ask about symptoms like fever or weight loss. Initial blood tests, such as a complete blood count (CBC), can provide clues about the presence of NHL.
The Role of Biopsy
A biopsy is crucial for diagnosing NHL. During a biopsy, a sample of tissue, usually from a lymph node, is removed and examined under a microscope. This helps determine the specific type of NHL, which is essential for planning treatment. In some cases, other tissues may be biopsied if lymph nodes are not accessible.
Advanced Imaging Techniques
Imaging tests like CT or PET scans are often used to detect NHL and guide biopsies. These scans help identify which lymph nodes or organs are affected, providing a clearer picture of the disease's spread. Imaging is also valuable in assessing the response to treatment.
