Listen to the interview below as Renee and Eliot Russman, President & CEO of Fidelco Guide Dog Foundation, talk about the astonishing fact that breast cancer does indeed affect dogs and cats too. 

To Recap..

In Dogs:

  • Mammary tumors are the most common type of cancer in unspayed, female dogs
  • Typically, these tumors are diagnosed in older dogs of 10 – 11 years old, although the cancer may have been developing for some time
  • Approximately 50% of these tumors are malignant
  • Dogs fed a high-fat diet, or overweight at 1 year old, are at increased risk of developing mammary tumors.

In Cats:

  • Cancer afflicts about 30% to 40% of all cats, and one-third or so diagnoses involve the mammary glands
  • Mammary cancer typically presents in middle-aged or older cats, and the prognosis is not as positive as with dogs
  • Unfortunately, over 85 percent of mammary tumors in cats are malignant and they tend to grow and metastasize quickly
  • Like breast tumors in humans, these start as a small lump in a mammary gland, and often, more than one mammary gland is affected. 

What can responsible pet owners do to protect their animals?

  • It’s really easy to check for breast lumps in dogs and cats…just add an additional minute of careful petting and loving time with them.
  • Ask your veterinarian to check for tumors with every visit…appropriate early treatment, even if the tumor is malignant, is often curative.
  • In cats, this disease is preventable by having females spayed before six months of age.
  • And, fatty, human food is not a good treat for our dogs or cats. Also…don’t forget the male dogs and cats at home…although very rare, mammary cancer does occur.
