Lung Cancer
Secondhand Smoke/Bennett Study
A study by William P. Bennett, MD, formerly of the National
Cancer Institute (NCI) and now associate research scientist in City
of Hope’s Division of Molecular Medicine, and Curtis Harris, MD, of
the NCI, found that some women may be genetically susceptible to
lung cancer when exposed to the carcinogens in environmental
(secondhand) tobacco smoke. The study found that women who developed
lung cancer and were exposed to secondhand smoke were 2.6 times more
likely to have a specific genetic alteration in GSTM1, a cancer
susceptibility gene, than women who developed lung cancer but were
not exposed to secondhand smoke.
