Answer :
Final answer:
Tobacco smoke, pollen, and dust mites are allergens that can trigger asthma, an inflammatory condition of the airways. Unlike lung cancer, which is usually caused by smoking or air pollution, asthma is often triggered by an immune response to environmental allergens.
Explanation:
Tobacco smoke, pollen, and dust mites are allergens known to trigger asthma. Asthma is a condition characterized by the inflammation and narrowing of airways, which can lead to symptoms like shortness of breath, chest tightness, wheezing, and coughing. Environmental factors, such as these allergens, can provoke an immune response in sensitive individuals, sometimes resulting in asthma attacks or bronchospasms. These attacks can be severe and require medical attention to relieve the symptoms and manage the underlying inflammation.
While asthma can be triggered by these common allergens, it is essential to distinguish it from other respiratory conditions such as lung cancer, which is most often caused by smoking or severe air pollution rather than allergens. Each condition has different risk factors and mechanisms underlying their development.
