as a fairly partial party (I like gas stovetops, don't own one):
statistically significant doesn't necessarily measure how important the effect is (or translatable to real life scenarios)
one study found people exposed to ~50 mg/m^3 benzene for 4 months to 16 years developed cancer (with some studies reporting ~20 mg/m^3, and a minimum of 2 mg/m^3 over 6 years)
this study reports ~3-6 ug/m^3, which is at a minimum 3 orders of magnitude less than the what was previously reported to cause cancer. (and also uses this 3 ug/m^3 based on some california recommendation)
TL;DR does it emit benzene? yes.
does it emit enough to cause cancer? untested. extrapolated answer: probably not.
