It could be an abscess, or a lipoma (which is benign, but can press on nerves nearby) If it is touchy and painful, it is possible it could be an
abscess. Sometimes, even lipomas are sensitive. Lots of lumps are not necessarily cancer. My
dog is lumpy as a rice pudding, but they are not malignant.
There is only one way to find out....,.go see the vet! If by any chance it happened to be a malignant lump, the best plan would be to have it taken off as soon as possible.
