In reality, cancer is a disease process where a cell continually divides and makes new cells, and doesn't respond to the body's normal signals to slow or stop its division. In benign tumors, the abnormal cells accumulate in one region and form a mass that doesn't spread to distant areas.
Dogs can develop many different kinds of tumors.
Usually, cancer occurs in middle-aged to older dogs, but certain types of cancer also occur in younger dogs. Cancer of the urinary bladder occurs in dogs and cats. Transitional cell carcinoma is the most common tumor of the urinary tract in dogs, and tends to occur in older dogs, most often female, and more frequently in certain breeds such as Scotties and Shelties. Dogs can develop several different types of bladder tumors, including cancer of the muscle wall and cancer of the inner lining cells of the bladder. Cancer of the lining cells, called transitional cell carcinoma, is the most common type of tumor of the urinary bladder in the dog.
