Prostatic Tumors

Prostatic tumors or prostatic neoplasia is cancer of the prostate gland. All tumors of the prostate gland should be considered malignant, as there has not been a report of a benign prostatic tumor. The most common tumor of the prostate is prostatic adenocarcinoma. Transitional cell carcinoma is also seen.

The incidence of prostatic disease is fairly low in dogs, and very rare in cats. The cause of prostatic neoplasia is unknown.

Prostatic cancer may affect any breed of dog, but is usually seen in older (average age is about 9-10 years old), medium to large breed dogs. It only occurs in male animals. Castrated male dogs and intact (non-neutered) male dogs are equally as likely to get prostatic cancer.
