Gene variant may raise lung cancer risk from radon

NEW YORK  - Gene variants that lead to   decreased amounts of an enzyme known as GSTM1 may raise the   risk of lung cancer related to radon exposure, new research   suggests. The gene variants also seem to increase the   cancer-causing effect of secondhand smoke.

Smoking during pregnancy is  known to raise a child's future asthma risk, but children with  a particular gene variation may be especially vulnerable, a  study published Tuesday suggests.

It&#39;s now well known that people who carry mutations in the BRCA 1 and 2 genes are prone to ovarian and breast cancer, but new findings show that these genes also increase risk of certain other cancers as well.

WEDNESDAY, Sept. 5 (HealthDay News) -- An experimental lung cancer screening test designed to look for precancerous genetic damage could help better identify patients at risk for the disease, while opening up the possibility for earlier diagnoses and preventive treatments, a new study suggests.
