Lung Cancer is increasingly being diagnosed in people under 40, raising concerns among health experts. While smoking remains a major risk factor, pollution, passive smoking, genetic factors, occupational exposure, and lifestyle changes may also contribute to rising cases in younger adults. Warning signs include persistent cough, chest pain, breathlessness, coughing up blood, unexplained weight loss, and repeated chest infections.
Doctors use imaging tests such as chest X-rays, CT scans, biopsies, and lung evaluations for diagnosis. Early detection is critical because symptoms in younger individuals are often overlooked or mistaken for common respiratory illnesses.
