Cancer (also called tumours or neoplasia) is one of the main causes of death in dogs, cats and
other species. Here are 10 interesting facts about cancer.
- Cancer is "an abnormal mass of tissue, the growth of which exceeds
and is uncoordinated with that of the normal tissues, and persists in the
same excessive manner after cessation of the stimulus which evoked the
change" (after Willis). In other words cancer consists of cells that
grow out of control of the body's normal regulatory mechanisms.
- Cancer affects all vertebrate species and is a major cause of death in
many species including humans, dogs and cats.
- Cancers usually - but not always, occur more frequently in older
- Not all forms of cancer are very serious. Warts (papillomas) are a form
of cancer but they are benign.
- There are two types of cancer - benign forms remain local and do not
spread to other parts of the body. Malignant cancers are more serious and
may be life-threatening because they have the potential to spread to other
parts of the body eg to the lungs, liver, skeleton or brain.
- It has been estimated that a sugar-cube sized malignant growth (eg
breast cancer) may contain 1000 million malignant cells - so early
detection and treatment is very important.
- Some forms of cancer can be caused by virus infections. eg Feline
Leukaemia virus can cause a malignant cancer - lymphosarcoma - in cats
- White cats can get cancer of extremities such as their ear flaps,
through exposure to too much sunlight
- Some cancers - eg lymphoma in the dog, are affected by nutrition and
dietary management is an important part of their management
- MOST FORMS OF CANCER CAN BE MANAGED SUCCESSFULLY -
the signs associated with the disease and the growth or spread of the
cancer can be delayed or prevented - even if the patient can not be
