There is an emerging body of research study that recommends direct exposure to wildfire smoke might increase the danger of establishing cancer and passing away from it. 1-3
Previous research studies have actually recommended that air contamination– particularly, great particle matter 2.5 microns in size or smaller sized (PM2.5)– might increase the danger of lung cancer, breast cancer, intestinal cancers, and genitourinary cancers. 4-7
Research study has actually likewise exposed associations in between PM2.5 direct exposure and an increased danger of death amongst cancer clients, consisting of those with lung, breast, intestinal, gynecologic, main nerve system (CNS), and hematologic cancers. 8-10

Associations in between wildfire smoke and cancer are less well studied. Nevertheless, “the offered research studies … have actually shown that short-term and long-lasting wildfire smoke direct exposure is connected with increased danger for a number of kinds of cancers, higher death from a number of cancers, even worse survival following treatment of particular cancers, and more barriers to accessing cancer care,” stated Raj Fadadu, MD, from the University of California, San Francisco.
Wildfire Smoke and Cancer Dangers
In a research study released in 2022, scientists analyzed associations in between long-lasting wildfire smoke direct exposure and the occurrence of numerous cancer enters more than 2 million individuals in Canada over an average follow-up of twenty years. 1
Compared to unexposed people, individuals who were exposed to wildfires within 50 km of their homes in the previous ten years had a greater danger of lung cancer (changed threat ratio [aHR], 1.049; 95% CI, 1.028-1.071) and brain growths (aHR, 1.100; 95% CI, 1.026-1.179). There was no association in between wildfire smoke direct exposure and hematologic cancers, nevertheless.
Another research study from 2022 revealed that wildfire-related PM2.5 direct exposure was connected with an increased danger of cancer death. 2 Scientist examined more than 1.3 million cancer deaths in Brazil and discovered that the danger of death from all cancers increased with each 1-μg/ m 3 boost in wildfire-related PM2.5 direct exposure (relative danger [RR], 1.02; 95% CI, 1.01– 1.03; P <
