Dogs + Tumors

  • In some cases, chronic inflammation of the nose (rhinitis) leads to proliferation (hyperplasia) and formation of polyps in the nose or throat. These polyps are not cancerous but may need removal.

  • 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.

  • 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, or bone cancer, is common in large breed dogs and is very aggressive, with upwards of 90-95% of patients having micrometastasis. Osteosarcoma is very painful. Lameness or a distinct swelling may be noted. Amputation is by far the most common treatment with chemotherapy following surgery. Radiation therapy may also be an option.

  • Ovarian tumors are quite rare in North American pets, mainly due to routine spaying practices. Several types of tumors can arise from the tissues of the ovary. How the tumor will affect your pet is entirely dependent on the location and type of tumor. By far, ovarian cancer is most commonly diagnosed by abdominal ultrasound or during a spay procedure. Full staging is recommended prior to surgery to determine if the cancer has metastasized. Treatment for solitary masses without evidence of spread typically involves ovariohysterectomy. If metastasis is present, chemotherapy should be considered, however its efficacy is not completely known. Without evidence of spread, ovarian tumors carry a good prognosis.

  • 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.

  • 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.
