Emphysema and Pneumonia Increase Risk for Lung Cancer
According to the journal Lung Cancer, individuals with a history of emphysema and pneumonia have an increased risk of developing lung cancer. However, further study is needed to confirm these findings.
Researchers from Quebec, Canada, recently evaluated data from two clinical studies to look for an association between non-cancerous medical conditions affecting the lung and a subsequent risk of developing lung cancer. The lung conditions evaluated for their relation to lung cancer risk included asthma, tuberculosis, emphysema, and pneumonia.
