For most patients who are lifetime non-smokers or have minimal tobacco use, we begin by evaluating other potential risk factors, such as exposure to asbestos. This was particularly common among individuals who served in the military, worked in insulation or construction, or were employed as mechanics—especially when brake pads contained asbestos. Miners are also at risk, though mining isn’t as prevalent in California. Another environmental factor is radon gas, which naturally emits from the ground in certain regions of the country. Homeowners can have their properties tested for radon, and if elevated levels are found, there are methods to ventilate the area beneath the home to prevent the gas from accumulating inside. While you can’t remove radon gas from the earth, you can reduce its impact within your home.
Additionally, particulate matter from fires—whether from wildfires, tobacco use, or wood-burning fireplaces—can irritate the lungs and contribute to conditions like restrictive airway disease, emphysema, and bronchitis. Long-term exposure to this particulate matter may also be carcinogenic. The challenge lies in determining how much exposure becomes dangerous, as individual risk varies. Nevertheless, it's strongly recommended to minimize exposure to particulate matter from any source, including smoking and indoor fireplaces.
Radon is a naturally occurring gas found in soil, and certain geographic areas have higher concentrations. If your home is located in one of these regions, it's important to test the property and install ventilation systems if needed to prevent the gas from seeping into your living space. Maps are available that show radon-prone zones, and testing and mitigation services are accessible to help reduce the risk.
