Cats + Tumors

  • 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.

  • Plasma cells (plasmacytes) are specialized cells that function as part of the body's immune system. They are formed from 'B'- type lymphocytes.

  • Salivary cancers are almost invariably malignant tumors originating from the secretory cells of the glands. Other swellings or tumors of salivary glands may be due to infections and cysts.

  • This tumor is a disordered and purposeless overgrowth of sweat gland cells. Most sweat glands are attached to the hair follicles (paratrichial, or beside the hair) but a few are not associated with follicles (atrichial).

  • This slow-growing tumor is a disordered overgrowth of cells of the epidermis, or outer layer of skin. It gets its name from its resemblance under the microscope to the basal cell layer of epithelium.

  • This is one of many similar tumors that arise by disordered growth of the hair follicles. Almost all of these tumors are benign and can be permanently cured by total surgical removal.

  • Melanocytes are cells that produce a pigment called melanin. They are found in many parts of the body where there is pigment, particularly skin, hair and eyes.
