Apocrine gland anal sac adenocarcinomas (AGASACA) are malignant tumors of the anal glands. These are paired glands located on either side of the rectal opening. Anal glands are sweat glands that contain a brown, malodorous liquid that is eliminated upon defecation.
How is Agasaca diagnosed?
Blood tests (complete blood count and serum chemistry panel) are done to assess the patient’s overall health and record the serum calcium level. Further diagnostic tests include abdominal ultrasound and thoracic radiographs or whole-body CT scan, and aspirates of local lymph nodes to evaluate for disease spread.
How do you get adenocarcinoma?

How is adenocarcinoma treated?
Treatment options There are three main treatments for adenocarcinomas: surgery to remove the cancer and surrounding tissue. chemotherapy using intravenous medications that destroy cancer cells all over the body. radiation therapy that destroys cancer cells in one location.
What is the survival rate of adenocarcinoma?
Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time (usually 5 years) after they were diagnosed….5-year relative survival rates for small intestine cancer.

For perianal adenocarcinomas, the treatment of choice is complete surgical excision of the tumor (sometimes with removal of the nearby lymph nodes) and neutering. Radiation or chemotherapy is recommended for these types of tumors. With successful therapy, the high blood calcium level will return to normal.
What is the function of apocrine?
Apocrine sweat glands, which are usually associated with hair follicles, continuously secrete a fatty sweat into the gland tubule. Emotional stress causes the tubule wall to contract, expelling the fatty secretion to the skin, where local bacteria break it down into odorous fatty acids.
