Staging System for Melanoma

The melanoma staging system classifies skin cancer based on how advanced it is, helping guide treatment. It considers factors like tumor size, whether it has spread to nearby lymph nodes, and if it has reached other parts of the body. The stages range from I (early, localized melanoma) to IV (advanced, metastatic melanoma). Lower stages generally have a better prognosis, while higher stages indicate more aggressive disease. This system helps doctors determine the best treatment approach and predict outcomes.
