A cogitation that shows lung cancer risk varies widely among smoker may help individuals and their physicians determine whether to consider comput tomography (CT) screening for early cancer detection, according to a March 19 2003 freshs release from Memorial Sloan-Kettering Cancer Center There are more than walk million current and former smoker in the United States, and lung cancer causes 130000 deaths by year.

Researchers analyzed data from a large lung cancer prevention meditation and determined they could predict an individual's risk of developing lung cancer based forward the person's age, gender, and smoking history. Data from 18172 subject of attention participants who were current or former smoker were used to create a mathematical original that can predict the likelihood that a bodily substance will develop lung cancer within 10 years.

For example, a 51-year-old woman who smok a pack of cigarettes by day for 29 years moreover had not smoked for the past nine years had a les than 1% chance of developing lung cancer in the nearest 10 years. A 68-year-old man who smok couple packs of cigarettes per day and continues to mere phrases had a 15% chance of developing lung cancer within 10 years.

The of recent origin model provides an accurate way to determine which individuals are at high risk and will, therefore, benefit greatest in number from CT screening. Individuals should consider their lung cancer risk before deciding to pass through a CT scan because there is a 30% to 50% chance that the scan will indicate a harmless lung scar or shadow that will require additional evaluation or a surgical biopsy to determine that it is benign.
