Adrenal Gland Tumors -------------------- General Information The adrenal glands are small structures that lie near the kidneys. Each gland consists of 2 major portions: the cortex and the medulla, which produce hormones that perform many essential tasks. Tumors of the adrenal glands cause an overproduction of hormones. Major signs of adrenal gland tumors include excessive thirst, increased urination, hair loss, an enlarged or sagging abdomen, reduced stamina and progressive deterioration of general health. This group of signs is called Cushing's disease. Adrenal gland tumors may be non-cancerous (benign) or cancerous (malignant). If cancerous, the prognosis (medical forecast) is usually poor. If you decide to have the tumor removed, a sample (biopsy) of the tissue will be submitted to a laboratory to determine whether it is cancerous. Important Points in Treatment 1. Hospitalization and major abdominal surgery are required to remove an adrenal gland tumor. 2. Laboratory tests are required to properly evaluate your pet's condition before and after surgery. Notify the Doctor if Any of the Following Occur: * Your pet chews or damages the sutures or incision. * You cannot give the medication as directed. * Your pet's general health declines.
