Frequently Asked Questions
Can non-smokers get lung cancer?
Yes, while tobacco smoking is the leading cause, lung cancer can also occur in non-smokers due to radon exposure, secondhand smoke, air pollution, occupational carcinogens like asbestos, or certain genetic mutations.
Why is lung cancer often diagnosed late?
Early lung cancer frequently causes no symptoms, and by the time symptoms like persistent cough, weight loss, or coughing blood appear, the disease has often already progressed, which is why low-dose CT screening is recommended for high-risk individuals.
What is molecular testing and why does it matter for treatment?
Testing the tumor tissue for specific genetic mutations helps identify which targeted therapies or immunotherapies are likely to work best for that individual's cancer, allowing more personalized treatment than chemotherapy alone.
Does quitting smoking help even after a lung cancer diagnosis?
Yes, quitting smoking after diagnosis can improve treatment effectiveness, reduce complications from surgery or radiation, and improve overall survival, so it remains valuable at any stage.
Who should get screened for lung cancer?
Low-dose CT screening is generally recommended for older adults with a significant smoking history, even if they've since quit, as it can detect lung cancer at an earlier, more treatable stage.
