Step-by-Step Surgery for Anal Sac Cancer

Anal sac cancer causes local problems, mainly because of pain and straining to defecate. Anal sac apocrine gland adenocarcinoma also leads to systemic issues, including hypercalcemia and metastasis. Affected patients are older female dogs in 90 percent of the cases. A few cases have been described in cats.

Differential diagnosis for perianal disease includes anal sac impaction, abscess (which may rupture), sacculitis, perianal adenomas, perineal hernias, perineal fistulas and other malignancies, such as perianal malignant melanoma. Any of these conditions affect the quality of life of the patient.
