Way,way OT - Cancer in mixed breed dogs

I have an interesting puzzle. My friend's mixed-breed dog developed a slow growing malignant tumour (hemangiopericytoma). Apparently, this occurs more frequently in mixed-breed dogs than in almost any purebreed. This fact struck me as really odd.

The few hypotheses I could think of don't really stack up
-genetic bottlenecks somehow reduce incidence?
-common heritage of mixes? (although she's part pitbull like most mixes, that breed isn't high risk
- mutts get more viral infections from living on street?

Any thoughts?
