SUMMER 2022 LYMPHOMA AND BLADDER CANCER IN DOGS TIED TO ENVIRONMENTAL RISKS Environmental pollutants and toxic chemicals have long been known to put people at risk for cancers such as lymphoma and bladder cancer. Researchers at the University of Wisconsin-Madison propose that dogs, too, may be at heightened risk for these cancers when exposed to harmful pollutants and chemicals. Urothelial cell carcinoma, also called transitional cell carcinoma, is the most common type of bladder cancer in people and dogs. In people with bladder cancer, about half of cases are due to smoking and about 20 percent are due to workplace exposures, but the cause of the remaining 30 percent is not well understood.
