Canine anal gland tumors in and around the anus (perianal tumors) can be divided in perianal gland tumors and anal sac tumors. Rectal tumors are also common in dogs. Perianal Gland Adenoma: Perianal glands are found anywhere around the anus, at the base of the tail and surrounding the male genitalia. Perianal gland tumors are often benign and occur frequently in male, intact dogs. Female dogs can be affected, however, although Cushing’s disease should be ruled out. These tumors are dependent on testosterone and will often disappear after castration. Multiple tumors can be present. In less than 5 percent of the cases, perianal gland tumors are malignant (fast growing) These tumors can grow fast. Cancerous cells can spread later in the growth process (call metastisis). Anal Sac Adenocarcinoma: Anal gland tumors (Adenocarcinomas) are usually seen in older female dogs. An anal tumor is very dangerous and can spread quickly to the lymph nodes. This type of cancer creates a secretion that increases calcium in the blood and can damage the kidneys.

Median survival for dogs with anal sac adenocarcinomas was 544 days and dogs with tumors < 10 cm having a significant better prognosis. Also, dogs with hypercalcemia and visible metastases did significantly worse. Learn More.
