Lung Cancer Rates Rising in Younger Women Who Never Smoked

Lung cancer remains the leading cause of cancer death in the U.S., but rates are rising among younger women aged 35-54, including those who never smoked.
Cigarette smoking is still the top risk factor, but other exposures like air pollution and radon may also contribute to lung cancer in nonsmokers.
Early symptoms can include persistent cough, upper back pain, shortness of breath, unexplained weight loss, hoarse voice, and coughing up blood.
Experts say routine screening for those at high risk could help detect lung cancer at earlier, more treatable stages.
Researchers are investigating reasons for the demographic shift, as well as improved diagnostic tools and treatments.
