– Dangerous glass fibers in cigarettes worsen lung damage for smokers (Natural News, May 04, 2012):
Shocking new research reveals that a specific type of lung cancer many smokers develop comes from tiny tears in their lung tissue caused by microscopic glass fibers, also known as glass wool, found in many conventional cigarette filters. These rips in the epithelial (soft) tissue fuel the development of tumors and cancerous cells due to the constant overload of toxins, namely pesticides, nicotine and ammonia, contained in commercial cigarette smoke.
The filters of typical commercial cigarettes contain microscopic, needle-shaped shards of glass wool (like fiberglass insulation) which escape into the mouth and throat, and then lodge with tobacco tar in the lung tissue, surrounding the alveoli (tiny air sacs) and lead to COPD (chronic obstructive pulmonary disease), emphysema and eventually lung cancer.
A physician’s assistant (PA) and an intensive care nurse at a major hospital reviewed the damaged lung tissue of several cigarette smokers and said the x-rays looked identical to those of patients exposed to asbestos, and that diagnostic imaging revealed what looked like “ground glass” which settled in the soft tissue near the bottom of the lungs (GGO – ground glass opacity). The interviewed nurse said, “When lung tissue is damaged over and over, it develops lesions, and the cancer plants itself in there like seeds.” (http://www.appliedradiology.com)
