Breathing in dust can significantly increase the chances of suffering from lung cancer because certain types of dust, especially in construction and industrial settings, can contain harmful particles such as asbestos, silica, or other carcinogenic substances. These particles can be inhaled and accumulate in the lungs, leading to chronic respiratory issues and potentially increasing the risk of developing lung cancer over time.

Options that involve exposure to sunlight and the consumption of processed foods are not directly linked to a higher risk of lung cancer. While excessive sun exposure can lead to skin cancer, it does not have the same association with lung cancer as inhaling harmful dust particles. Similarly, a diet high in processed foods may be related to other health issues, but it is not established as a direct contributor to lung cancer risk. Eating a high-fiber diet is generally associated with numerous health benefits, including a reduced risk of various cancers, making it a protective rather than a risk factor.
