Researchers don't yet know why, but about 80 percent of non-smokers
who succumb to lung cancer are women.

Lung cancer is generally thought of as a disease that mostly afflicts
male smokers. But according to a USA Today article, "Lung cancer
causes more deaths among women than breast, uterine and ovarian
cancers combined."

All women should take note of these four primary lung cancer
warning signs:

A cough that changes character (such as severity or frequency)

Awakened at night by coughing

Shortness of breath

Blood in sputum

What this author suspects is that the cause of such a cancer could be
passive smoking. If any of these symptoms are prolonged and there are
chances that you are a passive smoker, schedule a check up. Your
chances of survival are far greater when lung cancer is diagnosed in
the early stages.
