Hi Calhoun, sorry about your diagnosis but glad you found us. TO = No evidence of primary, N2= spread to one node greater than 3 cm but less than 6 cm, and MO = No distant spread beyond head/neck. Do you know if you the node showed HPV+? HPV cancers are generally more responsive to treatment. I know there are a few folks here who had unknown primary cancers and they will have more insight.

Good luck to you!
