Exposure to air pollution, including PM2.5 particles, increases the risk of throat and neck cancers. Studies show a 14% increased risk of laryngeal cancer associated with PM2.5 exposure. Another study found a 20% increased risk of nasopharyngeal cancer linked to exposure to nitrogen oxides (NOx). Air pollutants cause throat irritation, inflammation, and DNA damage, leading to cancer. Common symptoms include persistent throat irritation, dry cough, and difficulty swallowing.
