Cancer staging is typically done using the TNM system, which stands for Tumor, Nodes, and Metastasis. Each component is assessed and given a number to describe the extent of the cancer:
T (Tumor): Size and extent of the primary tumor (T1-T4) N (Nodes): Degree of spread to regional lymph nodes (N0-N3) M (Metastasis): Presence of distant metastatic spread (M0-M1)
The combination of these values helps to assign an overall stage, typically from I to IV, with higher stages indicating more advanced disease.
