Unfortunately, the only way to understand the exact nature and origin of the lump would be through to your veterinarian clinical examination and laboratory tests. Clinical appearance can help differentiate among infectious and neoplastic disease but only by collecting a specimen of the lesion will give you a specific and definitive answer. A biopsy can be taken under general anesthetic/sedation, otherwise a smaller sample collected with a fine needle can be aspirated without anesthesia/sedation. If you cannot bring Popart to the vet, take a picture and post again on the forum we might be able to help you further by looking at the pictures. I hope my answer was helpful.
