lung cancers

More than one in four of all diagnosed cancers involve the lung, and lung cancer remains the most common cancer-related cause of death among American men and women. In 2008, more than 161,000 lung cancer deaths are expected, outnumbering deaths from breast, prostate and colon cancers combined.
At the same time, it may well be that a great many lung cancers are preventable. Inhaling cancer causing substances such as tobacco smoke may lead to changes in the lung tissue shortly after exposure so called precancerous changes. Nevertheless, cancer itself typically develops over a period of many years, and if detected at an early enough stage can be eliminated by a variety of treatments.
