Dogs + Tumors

  • 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.

  • Like us, dogs can develop oral masses. Some will grow slowly and won't spread to other locations (benign), while others will spread to different areas of the body causing great harm (malignant).

  • 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.

  • 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.
