Anecdote: FWIW, domesticated horses living mostly in barns and given routine veterinary care hardly ever die of cancer. They will die of old age, colic, and aortic rupture, and are often euthanized, but I just do not recall hearing about horses suffering from cancer.
Whenever a famous horse dies, the news travels through the horse community and the stories will virtually always include the cause of death. Just this week, "Go For Gin," who won the Kentucky Derby in 1994, died at the age of thirty-one. Cause was given as heart failure. Not cancer, even at that very advanced age.
Somebody really, really needs to do a study on the cancer rate in horses routinely given ivermectin as a dewormer. It's been heavily used that way for at least the last 30-40 years.
