Here is the concept related slightly differently which may help (or not).
you are right - a complicated issue:

<<Cancer is a genetic disease, Dr. Avadhani explained. Yet cancer is
inherited in only five percent of cases. The rest spontaneously arise
following a primary DNA lesion that occurs during the life of an individual.
"It is this 95 percent of the population that's going to be extremely
important for understanding cancer in both humans and animals.

"Animals are exposed to the same environment and some of the same putative
causal factors that we are," he said. >>
