Diagnosing Bladder Cancer in Dogs

It is not uncommon for bladder cancer to first suspected when your pet's veterinarian feels the presence of a tumor during a routine examination. Tests that can be used to confirm a diagnosis of bladder cancer include:

  • Urinalysis to look for cancer cells in the pet's urine
  • Bloodwork to check for impaired kidney function
  • Abdominal ultrasound to look for tumors within the bladder 
  • CADET Braf testing

Life Expectancy of Dogs with Bladder Cancer

Sadly, the prognosis isn't good for dogs with bladder cancer. Once diagnosed, dogs with bladder cancer will live for approximately 4-6 months without receiving treatment and 6-12 months with treatment.

Treatment for Bladder Cancer in Dogs

If your dog is diagnosed with bladder cancer your vet may recommend vet surgery, chemotherapy, radiation or a combination of these treatments. Due to the location of bladder tumors the full surgical removal of the tumor is typically not possible, although in some cases it may be possible to remove part of the tumor in order to temporarily relieve your dog's symptoms. That said, it's important for pet parents to note that the tumor will regrow after a time.

The CADET Braf Test

The CADET Braf test can help vets to detect the presence of a specific gene mutation that is linked to bladder cancers in dogs. The CADET Braf test can also be helpful in detecting bladder cancer before symptoms become evident, helping vets to determine the extent of the disease, and in determining what the best form of treatment may be. In some cases the The CADET Braf test is used to determine how a dog is responding to chemotherapy treatment.

If your dog is an at-risk breed for bladder cancer ask your vet whether the CADET Braf test is right for your dog.
