Approximately one in 16 women in the United States will develop lung cancer in her life. Lung cancer occurs when irregular cells grow rapidly within the lung tissues. Sometimes it begins in stealth mode with no symptoms.

There are two main types of lung cancer: small-cell and non-small cell. Small-cell is divided into two stages: limited (confined to one lung and possibly nearby lymph nodes) and extensive (cancer has spread to the other lung and beyond). Non-small cell is assigned to a stage of one through four, depending on how far it has spread.

Success in quitting smoking is the result of planning and commitment, not luck. Your doctor can help you customize a strategy which allows you to kick the habit once and for all.
