Check the bottom of this "cyst" for tiny legs. If there are legs, it is a fat tick which will fall off soon or which you should be able to easily remove. If you do not see legs this could be a cyst or a little tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. A cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.
