C ancer is an uncontrolled growth of cells on or within the body. C ancer is common in pet animals, and the rate increases with age.
Dogs get cancer at roughly the same rate as humans, while cats get fewer cancers.
Cancer accounts for almost half of the deaths of pets over 10 years of age. S trong circumstantial evidence of cancer can be attained from x-rays, blood tests, the physical appearance of the cancer, or the physical signs caused by the cancer. S ome cancer, such as breast cancer, is largely preventable with early spaying. Unfortunately, the cause of most cancers is not known and therefore prevention is difficult. Most skin tumors in cats are malignant, but in dogs they are often benign.
