Understanding Vaccine Associated Feline Sarcoma

also see Feline Fibrosarcoma 

In 1991, a link was found between feline sarcoma and vaccine sites, with a noticeable percentage of the cancerous tumors that affect cats occurring at common vaccine sites. However, the majority of feline sarcomas are not associated with vaccinations, so pet owners should not forgo vaccines in order to prevent the cancer.

Feline Sarcoma Appears Suddenly

The most common site for the tumor to be located is between the shoulder blades. The tumor appears quickly, almost overnight. If you feel a large growth, take your cat to the vet for a biopsy, as this is a sign that the cancer is in the early stages.

Vaccine Benefits Far Exceed Slim Chance of Bad Reaction

Vaccine-associated feline sarcomas are far more rare than the diseases your cat's vaccine protects them from. Though you should consider vaccine sites carefully later in life to determine if your cat has developed any tumors, it's important not to abstain from any vaccines, as they can protect your pet's life, as well as your own as a result of the rabies vaccine.

Erring on the side of safety, discuss your vaccination options with your vet. Vaccinate only for the diseases that your pet could come into contact with in order to avoid unnecessary vaccinations.
