Q. My italian greyhound is riddled with fatty tumors ....how come
DESTINI R. HOLLOWAY, DVM
A. Oftentimes pets get lipomas (fatty tumors) as they get older. These are natural progression as the skin and body age the normal proliferation (growing) of cells can be altered, just like and old car that doesn't run so well or runs slower with age. Even thought the tissue is benign (non-cancerous), it is still abnormal tissue due to a breakdown in the normal turn-over rate of skin cells.
No need to worry about lipomas, however lipomas have been shown to be able to turn into cancerous cells in some cases, so it is always advised to have any new or growing masses checked by a vet to ensure they are nothing to worry about.
