I wondering if this is squamous cell carcinoma? (Photo)

This spot appeared to have shown up after getting head from my girlfriend at the time roughly 9 months ago. It doesn't itch or hurt its just there. I saw to GP's and they both don't know what it is. I have applied everything on it and nothing works except for maybe Aloe Vera it seems to help slightly but could be my imagination. If nothing is working I am stressing it might cancer.
