The antibiotics did nothing to alter the size of the lateral neck mass, which prompted a visit to an ENT. At this point, I was 100% convinced that I had cancer based on everything that I read. The only question was what “type” of cancer and its stage. After spraying my nasal cavity with a numbing agent, the physician looked at my throat using an endoscope (e.g., examining my throat using a tiny, flexible camera inserted through the nasal cavity) that didn’t seem to indicate anything out of the ordinary. The next logical step was a CT scan to obtain additional information, which I promptly scheduled.
