New insights into why ex-smokers remain at elevated risk of lung disease
A new study from McGill University reveals that former smokers face persistent lung health risks due to lasting cellular and genetic changes. Researchers found that while some damage is reversible, other molecular signatures remain, explaining why ex-smokers are still prone to lung disease.
Why it matters
Understanding the long-term biological impact of smoking is essential for developing better screening and treatment protocols for former smokers.
