Wildfires can extend hospital stays for cancer patients, according to new research that points to concern among health experts about the potential effects that blazes have on people who are recovering from surgery.

Patients who were in a hospital as wildfires raged nearby remained admitted nearly two days longer on average than patients who were not close to a fire, said a study that was published this week in the Journal of the National Cancer Institute.

Researchers looked at national data of lung cancer patients who underwent surgery to remove tumors, and compared it to federal disaster declarations for wildfires in the same counties.

Chan School of Public Health.
