Yes - I vote for the SCC as well- take the biopsy results and get an appointment there - even if its far away - when dealing with this cancer it is better to have the best medical care. It does sound like its small which is great but small can be a big problem regardless its not usual but a highly aggressive cancer can appear superficial (small in size) but spread quickly. So time is of the essence. And some drs aren't familiar with oral cancer (even ENTs) maybe that's why your net couldn't spot it.

Best of luck.
