by contrast , the low alcohol groups ( lo-beer and lo-etoh ) showed a trend toward increased incidence and proportion of tumors in the left colon ( incidence of 42 and 35 % versus 15 % in control , p = 0.06 for lo-beer ; 28 and 30 % of tumors in left colon versus 11 % , p = 0.08 and p = 0.07 ) but no effect on right colonic tumorigenesis .
