My dog's lump grew and changed. Should I be worried about cancer?

Question

This started out as, what looked like, a mosquito bite a few years ago then turned into a, what I thought, scab. Over about 4 years it has grown and lately it has grown a lot faster. It used to be flat, but now is somewhat raised in the middle. Please don't tell me it's cancer. Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 18 years and 2 months old | 32 lbs

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors.
