Veterinary researchers at Oregon State University have identified a unique group of proteins that indicate the presence of transitional cell carcinoma – the most common cause of bladder cancer – and may lead to a new assay which could better diagnose this disease in both dogs and humans.

Sheepdogs, collies, and terriers seem particularly susceptible to this type of cancer. By the time the cancer is diagnosed, it is usually too late to save the dog’s life.
An improved assay to detect this serious disease much earlier in both animals and humans should be possible, scientists said, and may even become affordable enough that it could be used as an over-the-counter product to test urine, much like a human pregnancy test. Some of the work may also contribute to new therapies, they said.
“Research of this type should first help us develop a reliable assay for this cancer in dogs, and improve the chance the disease can be caught early enough that treatments are effective,” said Shay Bracha, an assistant professor in the OSU College of Veterinary Medicine.

This is an interesting post, I hope they can find a better treatment. Hate to see any animal suffer.
