“Lung cancer diagnosis often starts with an imaging test to look at the lungs. If you have symptoms that worry you, a healthcare professional might start with an X-ray. If you smoke or used to smoke, you might have an imaging test to look for signs of lung cancer before you develop symptoms.  People with an increased risk of lung cancer may consider yearly lung cancer screening using low-dose CT scans. Lung cancer screening is generally offered to people 50 and older who smoked heavily for many years. Screening also is offered to people who have quit smoking in the past 15 years. Discuss your lung cancer risk with your healthcare professional. Together you can decide whether lung cancer screening is right for you.  Treatment for lung cancer usually begins with surgery to remove the cancer. If the cancer is very large or has spread to other parts of the body, surgery may not be possible. Treatment might start with medicine and radiation instead. Your healthcare team considers many factors when creating a treatment plan.”
