As in humans and other types of animal, cancer in cats occur when cells start to grow uncontrollably and invade surrounding tissue. It may or may not spread to other areas of the body. And just like people, cats can get various types of cancer.
Although cancer has no single known cause, hereditary and environmental factors do play a role in cancer development in felines. For example, squamous cell carcinoma that occurs on the nose, ear, or eyelids is known to be caused by repeated exposure to sunlight, with light-coloured cats more susceptible than others). However, on of the most common types of cancer in cats is lymphosarcoma.
There are a few symptoms to look out for when you think cancer is an issue in a cat, stray or otherwise. These include:
- weight loss
- bad breath
- loss of appetite
At the first sign of any symptoms, take the cat to a vet for an examination and proper diagnosis. Do not assume that a symptom by itself is an indicator of cancer though.
