Cancer (neoplasia) is a change from normal cells into abnormal malignant
cells, and it can take many forms. Some involve solid masses, or tumors,
while others involve the blood or bone marrow in leukemia. Cancer can develop
in virtually any organ or body system. In addition, some cancers spread or
metastasize to other areas of the body. They can spread to nearby tissues,
or invade the blood stream or lymphatic system. Cancer commonly metastasizes
to the lung. The exact symptoms, treatment and prognosis vary with the specific
tumor type and situation.
This summer, remember that your dog is also at risk for skin cancer from
ultraviolet radiation. Short-haired and light-coloured dogs (and dogs
with sparse coats due to a skin disease are at the most risk. To be
safe, use an SPF-30 sun screen on areas not protected by the dog's coat,
including the tips of the ears, the bridge of the nose and near the eyes.
