"Berners have a 30% incidence of cancer." To properly evaluate what that statement realoly means, one would need to know more info.
What is the cancer rate in other breeds to compare #'s? What is the actual death rate from cancer in Berners? (Some cancers can be successfully treated. My Java has been free of mast cell for 2 1/2 years now.) What age did the dogs die from the cancer? (A 5 yr old dying from cancer is a different thing than a 13 yr old w/ cancer.) Do specific cancers run in certain lines? The term "cancer" encompasses an entire spectrum of quite different illnesses.
