How common is skin cancer in cats?

Skin cancer is fairly unusual, but any lump or bump in your cat needs to be checked. Cats and dogs both get different types of skin cancers, but cat skin cancer is substantially more aggressive than dogs. So any lump or bump in a cat I want to take a look at. We're going to aspirate it, try to get some cells from it, try to determine what it may be, and if it concerns us, because with skin cancer, the sooner we deal with it, the better.
