I have a quick question regarding classifying the M component of the TNM staging. If I have a lymph node that was metastases on the same side of my neck as the source (which is on left over tonsil tissue), would the classification be?

M0: Presence of distant metastasis cannot be assessed.
M1: No evidence of distant metastasis.
M2: Distant metastasis present
