Scientists have found that exposure to airborne PM2.5 pollutants significantly increases the risk of head and neck cancer. Research results It was published In the journal Scientific Reports (SciRep).
Air pollution is a known risk factor for various diseases. The International Agency for Research on Cancer (IARC) classifies PM2.5 as a Group 1 carcinogen that can cause lung cancer. PM2.5 is a mixture of fine particulate matter, dust, ash, soot, smoke and mineral or organic compounds.
Particular attention of researchers was drawn to the pollutant’s effect on head and neck cells, which are particularly vulnerable to carcinogens.
A study using SEER data (2002–2012) and county-level PM2.5 pollution information (US 1981–2016) confirmed that high PM2.5 levels were associated with increased incidence of head cancer and neck cancer. However, the increase in the concentration of harmful particles in the air was also associated with an increase in the number of cases.
Particular attention was paid to the location of the cancer: PM2.5 pollution significantly triggered mouth and throat cancer, but not malignant tumors in the paranasal sinuses, hypopharynx, nasopharynx, or oropharynx.
