Wildfire Smoke Exposure May Shorten Lung Cancer Survival
Doctors looked at a lot of people with lung cancer in California and found something interesting.
If these patients lived in areas with a lot of smoke from wildfires, they were more likely to die from their cancer.
The smoke makes the air bad, and the tiny particles in it get deep into your lungs.
For people who had never smoked before and had a very serious type of cancer, the risk was even higher.
However, if they were getting a special kind of treatment called immunotherapy, it didn't seem to make a difference.
Scientists think the smoke might change how the body reacts to the cancer, and they need to do more research to figure it all out.
Exposure to wildfire smoke may increase the risk of death for lung cancer patients.
A study tracked over 18,000 non-small cell lung cancer patients from 2017-2020.
Patients in areas with high wildfire pollution had a 20% greater risk of dying.
Non-smokers with stage 4 cancer were particularly affected, with a 55% higher risk.
Immunotherapy treatment may mitigate the negative effects of smoke exposure for smokers.
