Breast Cancer is Smoking Along

Cigarette smoke could be a cause of breast cancer after all, University of Florida researchers reported in a cellular cancer journal called Oncogene.

Breast cancer is one of the few cancers in which a link to smoking has never clearly been established.

The study differs in one key aspect from previous studies that have not found a clear link between smoking and breast cancer: The researchers used condensate from actual tobacco smoke, in which normal breast cells were exposed to the full range of the approximately 4,000 chemicals in tobacco smoke and not just a few of its known toxins. The condensate was injected into laboratory mice.

“It is very significant from a health point of view that in a single puff, you are taking in 4,000 chemicals, and we don't know what they are going to do, where they're going,” said Dr. Satya Narayan, one of the researchers.
