Tumors

  • Neuroendocrine cells produce specialized chemical substances called “neuroendocrine hormones”. These hormones affect the rates of specific chemical reactions in nearby cells or in other tissues throughout the body.

  • Oral papillomas (warts) are benign tumors of the epithelial lining of the mouth and throat caused by papillomaviruses. The esophagus may also be affected in severe cases.

  • Squamous cell carcinomas are malignant cancers originating from the lining cells of the mouth. They are locally invasive and often recurrent.

  • Osteosarcoma is the most common malignant bone tumor diagnosed in veterinary practice. It is considered similar to pediatric osteosarcoma in humans, a bone cancer that usually develops during the period of rapid growth that occurs in adolescence, as a teenager matures into an adult. Osteosarcoma is considered a rare cancer in cats.

  • The ovary contains several different cell types. These include the germ cells, which make the eggs, the supporting (stromal) and hormone-producing cells as well as epithelium, connective tissue and blood vessels.

  • The pancreas is a glandular organ located close to the liver, the stomach, and the small intestine. It has two main functions, an exocrine function and an endocrine function.

  • A “tumor” is a lump. Not all are cancerous. Panniculitis is usually visible as a lump but it is an inflammation of the subcutaneous fatty tissue and is not cancerous.

  • Papillomas are benign, sometimes multiple, tumors caused by viruses. They are commonly known as “warts”. The tumors often disappear spontaneously because the animal slowly develops immunity to them.

  • The four parathyroid glands (two on each side) are closely associated with the thyroid gland, located just below the larynx or “voice box” in the neck.

  • The pituitary gland is an endocrine gland located at the base of the brain. Endocrine glands produce specialized chemicals called hormones, which regulate and integrate many activities to maintain internal stability of the body.
