Researchers investigated the relation between baseline BMI and cancer incidence in 160,000 new cancers from a population of 5 million adults collected over 7.5 years from British general practices. Higher BMI was associated with increasing cancers of the uterus, gallbladder, kidney, cervix, thyroid, liver, colon, ovary, and breast (postmenopausal) and with leukemia. Cancers of the lung and oral cavity were attributable entirely to smoking and not BMI.
