CANCER IN PETS: WHAT PET OWNERS SHOULD
KNOW
MANHATTAN -- With about
380 of every 100,000 dogs and 156 of every 100,000 cats at risk for cancer each
year, pet owners are likely to have questions about how the disease, thought by
some to be found only in people, can affect their dogs and cats. Dr. Ruthanne Chun, assistant professor of clinical oncology at
What can cause
cancer in my pet?
Just like people,
excessive exposure to environmental toxins or sun may predispose animals to
developing certain kinds of cancer. Inappropriate breeding may also lead to
genetic abnormalities that result in an increased likelihood of developing
cancer.
How can I detect
cancer in my pet?
Pet your cat or dog
thoroughly once a week to feel for abnormal lumps, bumps or swellings. Be alert
for any area that appears to be painful when touched. Open wounds that are
ulcerated and don't heal in a reasonable amount of time also could be potential
signs of cancer. Nonspecific symptoms such as loss of
appetite, weight loss, vomiting or diarrhea also may
be causes for concern.
What does a
diagnosis of cancer mean for my pet?
Your veterinarian must
determine what type of tumor your pet has and how far
it has spread. The best way to determine if the tumor
is malignant (likely to spread to other parts of the body) or benign (grows
only in one area of the body) is to perform a biopsy. A biopsy, and additional
tests to determine whether or not the tumor has spread,
will help determine your pet's long-term outlook. If the tumor
is malignant, you and your veterinarian will have to decide the best treatment
for your pet.
What treatment
options are available for my pet?
There are three main options
-- surgery, chemotherapy and radiation therapy -- that may be used alone or in
combination depending on what type of treatment is needed. Your veterinarian
can tell you which treatment would be best for your pet.
How long is
treatment and will my pet require more than one cancer treatment?
Treatment varies
greatly depending on the tumor type.
How much does cancer
treatment cost?
Depending on the tumor type, cancer treatments can cost anywhere from $400
to $3,000.
What are common
cancers in pets?
Common cancers in pets
include skin cancers, cancer of the lymph nodes (lymphoma) and bone cancer.
What age are animals
more are risk?
Middle-aged to older
dogs are usually more at risk, but there are breed differences due to size: a
5-year-old Great Dane is considered old, while a 5-year-old toy poodle is still
young. Also, animals as young as six months have been diagnosed with cancer.
How regularly should
I take my pet to the vet for cancer check?
Annual physical
examinations are appropriate for young animals, twice a year is recommended for
older pets, but you should take your dog or cat to the veterinarian anytime you
suspect a problem.
What breeds of cats
and dogs are more at risk and why?
Golden retrievers tend
to have a high rate of cancer, likely because of a genetic problem. No cat
breeds are more at risk than any other. Other risks vary with the type of tumor. Large to giant breeds of dogs are more likely to be
diagnosed with bone cancer. Fair skinned dogs -- and white cats -- that are out
in the sun a lot are more likely to develop skin cancer.
