Does secondhand smoke cause lung cancer in infants?

Second hand smoke can cause lung cancer in infants.

If the infant inhales a small amount of secondhand smoke occasionally, it generally does not cause lung cancer. However, secondhand smoke contains a lot of tar, nicotine and other harmful components, which has a certain carcinogenic effect. The lung function development of infants is not perfect. If you smoke a lot for a long time, you can increase the risk of lung cancer, but you will not necessarily get lung cancer.

Parents need to create a good living environment for infants, keep the surrounding air fresh, and breathe more fresh air. Smoking is harmful to health. Parents are advised to quit smoking as soon as possible to reduce the risk of lung cancer.
