Cancer in cats is the leading cause of death among cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. Feline cancer initially manifests as a lump or bump on any part of the body. It rapidly grows in the affected cell, attaches itself to the tissue under the skin in that area, and, depending on the tumour, it can spread to other parts of the body.^[1] Although cancer accounts for approximately 32% of deaths in cats over ten years old, it can be successfully treated if diagnosed early.^[2]

While the causes of cancer in cats are unknown, feline leukemia virus is suspected to be a prime contributor.^[2] Other factors suspected to increase rates of feline cancer include toxins from the environment, passive smoking, excessive grooming, or licking parts of the body that have been in contact with an environmental toxin.^[2]

Cancer can be detected at an early stage by observing certain signs and symptoms. Common diagnostic methods include physical examination, x-rays, ultrasounds, cytology, blood tests, urine tests, and nuclear scans. Depending on the type of cancer and its level of progress, surgery, radiation, chemotherapy, or immunotherapy may be used to treat the cancer. Although research into causes and treatment of feline cancers has been slow, there have been advances in radiation therapy, as well as newer and improved chemotherapy procedures.^[2]
