Section: Overview
Renal neoplasia is cancer located in the kidney. Renal neoplasia can originate in the kidney (primary) or spread or metastasize to the kidney from another site (secondary).
Most renal tumors are seen in middle aged to older dogs and cats. Nephroblastomas, rapidly developing malignant tumors, are seen in younger animals. Carcinomas are thought to be more prevalent in the male dog. About 50 percent of cats with renal lymphoma are feline leukemia virus positive.
Generally, there are no specific causes of cancer identified and cancer of the kidney is rare in dogs and cats.
