TL;DR: No substantial short-term beneficial effect on incidence or mortality for this type of cancer occurred following daily supplementation with multiple vitamins and minerals among adults with precancerous lesions of the esophagus.

TL;DR: It is suggested that the disproportionate distribution of blacks at lower socioeconomic levels accounts for much of the excess cancer burden among blacks and for both blacks and whites unidentified racial factors, which may be either cultural or genetic, may play a role in the incidence of some cancers.
