Lung Cancer: Family History Matters


http://theluckyberry.com

Smoking causes most lung cancer; but women appear to be vulnerable to another risk factor - their genes.

Women with a family member who has been diagnosed with lung cancer are nearly three times as likely to develop the disease. Men's risk is nearly doubled by having a close relative with the disease.

It seems that certain inherited genetic patterns leave people more susceptible to lung cancer.
Even nonsmokers face increased risk if their mother, father, or a sibling developed lung cancer.

Other causes include second-hand smoke and exposure to radon, an oderless, invisible gas that occurs naturally in soil and rock.

To decrease lung cancer risk, avoid cigarette smoke and other chemical pollutants, and eat a healthy diet. See your doctor if you have a recurring cough, hoarseness lasting more than two weeks, trouble breathing, chest pain, or if you cough up blood - all could be signs of lung cancer.
