Introduction
Excessive formaldehyde exposure usually does not cause lung cancer. However, long-term exposure to formaldehyde may increase the risk of lung cancer, although actual outcomes vary from person to person. A detailed analysis is as follows: formaldehyde typically does not directly cause lung cancer, but since formaldehyde is classified as a carcinogen, prolonged or repeated exposure may increase cancer risk. Short-term exposure generally does not lead to cancer, but it might cause pulmonary discomfort, such as coughing and dryness in the lungs. If lung cancer does develop...
Exposure to excessive formaldehyde usually does not cause lung cancer. However, long-term exposure to formaldehyde may increase the risk of developing lung cancer. The actual impact varies from person to person. Detailed analysis is as follows:
1. No
Formaldehyde typically does not directly cause lung cancer. However, formaldehyde is classified as a carcinogenic substance. Short-term or single exposure generally does not lead to cancer but may cause respiratory discomfort, such as coughing and dryness in the lungs. If lung cancer is diagnosed despite minimal exposure to formaldehyde, it is advisable to consider whether chronic lung conditions have been left untreated. In such cases, prompt medical evaluation to identify the underlying cause and receive targeted treatment is recommended.
2. Yes
Formaldehyde is widely used in daily life. Building materials commonly used in indoor renovations—such as plywood, paint, and carpets—contain and release formaldehyde. Humans are primarily exposed to formaldehyde through inhalation, ingestion, and skin contact. Long-term exposure to formaldehyde may lead to lung cancer. Furthermore, prolonged exposure to formaldehyde can impair respiratory function and disrupt nervous system signaling. In severe cases, formaldehyde may cause genetic and chromosomal mutations. Therefore, it is important to avoid formaldehyde exposure.
If one must remain in a formaldehyde-contaminated environment for an extended period, wearing a mask is recommended to provide some protection. If significant symptoms develop, prompt medical evaluation is advised, followed by appropriate treatment based on the individual's condition.
