In cancer staging, the 'N' component assesses what?

Explanation:
N terminology in cancer staging reflects whether the cancer has spread to nearby regional lymph nodes and how extensive that spread is. This information, combined with the tumor’s size/extent (T) and the presence or absence of distant metastasis (M), helps determine the overall stage and guides treatment decisions. So, the extent of regional lymph node involvement is what the N component measures. The other factors listed are different concepts: the degree of cell differentiation relates to histologic grade, distant metastasis maps to the M component, and tumor margin status refers to surgical margins, not the N category.
