The following risk assessment tool is intended to help you determine your risk of lung cancer in the next year (i.e., 1-year lung cancer risk). Clinicians at MD Anderson Cancer Center developed a lung cancer risk model for smokers and ex-smokers using numerous risk factors known to have a significant association with lung cancera. This simplified version uses only gender, age (over 40) and smoking history.
If you have a pulmonary nodule, please use the Nodule Lung Cancer Risk Calculator.
Calculate lung cancer risk below:
I am currently years of age
MD Anderson risk tables do not contain data for patients younger than 40 years old.
I have never smoked
If you have smoked in your lifetime, please complete the following fields
I currently smoke
I began smoking at age:
I smoke an average of
0.511.522.533.544.555.56 packs per day.
I quit smoking
I quit smoking at age *this calculator assumes 20 pack years for an ex-smoker
*Note: This risk calculator is not for individuals under the age of 40 or who have a smoking history of less than 20 pack-years. (A pack-year is calculated by multiplying the number of packs of cigarettes (20 cigarettes per pack) smoked per day by the number of years smoked. For example, 20 pack-years is the equivalent of having smoked 1 pack of cigarettes every day for 20 years or 2 packs of cigarettes per day for 10 years.)
