Lung Cancer Screening, Version 1.2017


Should you start now?

Start before you have symptoms

Start before you have symptoms

Screening can help find disease early, before

symptoms occur. If you find disease early, you can

start treatment and have a higher chance of a cure.

The goal of lung cancer screening is to find lung

cancer when treatments will work best. Treatments

usually work best if started at the earliest stage

of cancer, before there are symptoms of cancer.

However, at this time, most lung cancer is found after

symptoms appear.

Common symptoms of lung cancer are listed


Guide 2

. See your doctor if you have these

symptoms. Most often, these symptoms are caused

by health problems other than lung cancer. If your

doctor thinks your symptoms may be caused by lung

cancer, he or she may suggest other types of tests

to check for cancer. If you have no symptoms of lung

cancer, a screening program may be right for you.

Certain people are at risk for lung cancer.

Because of this risk, it is important to tell your doctor

about your health history and your family’s health

history. Let the doctor know if you smoked in the

past and how many years it has been since you quit.

Also, let the doctor know if you smoke now. Your

doctor can then share the level of risk you have for

lung cancer. The level of risk can be high, moderate,

or low. If you are at high risk, learn about your

screening options.
