Worried 'mom'

So my dog has a small looks like cyst by her eye. Should I be worried? Is that what cancer starts out like. I mean other then the small cyst she is fine. Energetic and her coat is very shiny and healthy.

Any help would be great to put my mind at ease!

When my cat had a small lump on him, I took him to the vet for tests, he was otherwise perfectly normal. Turned out to be nothing, but I didn't want to take any chances.
If I were you I would schedule an appointment to get it looked at.
