Lung cancer may be caused by wood smoke
by Mike Adams, the Health Ranger, NaturalNews Editor
A new study suggests that wood smoke may cause lung cancer even in non-smokers.
Burning wood may be associated with lung cancer, even with people who do not smoke, suggests a new study.
Scientists from Mexico gathered blood samples from 62 patients with lung cancer, 9 patients with chronic obstructive pulmonary disease (COPD), and 9 control subjects.
Of the patients with lung cancer, 23 were tobacco smokers (37.1 percent), 24 were exposed to wood smoke (38.7 percent), and 15 were not in either category (24.2 percent).
Study results show that 38.7 percent of the patients with lung cancer were nonsmokers who were exposed to continuous wood smoke for over 10 years.
Most of these people were women living in rural areas, with poverty conditions.
The findings not only suggest a connection between lung cancer and exposure to wood smoke but they also indicate that wood smoke may cause similar gene mutations to p53, phospho-p53, and MDM2 protein expression as tobacco use.
The study appears in the July issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians.
