Stage II means they caught it early. We all empathize with you as the worst time is going through the Dx phase before a treatment plan is given. When I got my Dx, I passed out in the ENT's office! I went on anti-anxiety meds for quite a while. Typically with stage II you will have many treatment options also, maybe even non-surgical. Hang in there! Breath deep, take it one day at a time.

A cancer's stage is based on information about the original (primary) tumor:
The tumor's size
Whether or not the tumor has grown into other nearby areas
Whether or not the cancer has spread to the surrounding lymph nodes
Whether or not the cancer has metastasized (spread) to distant areas of the body
