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.
