Lung disease is fatal for 86 percent of its victims within five years of a diagnosis, and is the leading cause of cancer death among women, exceeding even breast cancer. Researchers continue to study the causes of lung cancer and to search for ways to prevent it. But, about 90% of all lung cancer deaths among women are from smoking. Even though it is well known that the effects of smoking are harmful, an alarming number of women continue to smoke. The effects of tobacco seem to be far more damaging to women than to men. Scientists have discovered that a gene that accelerates lung cancer growth is more active in females. This book presents the latest research in this dynamic field.
