Secondhand Smoke and Your Lung Cancer Risk

Secondhand smoke is a type of smoke that you did not intend to breathe in. Secondhand smoke exposure is caused by either side stream or mainstream smoke. Tobacco, such as cigarettes, cigars, or pipes, emit sidestream smoke when they are lit; meanwhile, a smoker will exhale the mainstream smoke. Both of these types release toxic compounds into the air, which do have a harmful impact to the nonsmokers. Secondhand smoke can cause a variety of health issues in infants and toddlers, including increased the prevalence and severity of asthma attacks, lung infections, ear infections, and sudden infant death syndrome (SIDS). At this rate, smoking cessation is a good way to prevent these health issues from happening to your loved ones.

People seem to believe that opening windows or using a ventilator would keep them safe from secondhand smoke. Unfortunately, according to researchers, the toxins in the smoke will not go away even if you take these initiatives. They still very much can be found in people’s hair, clothing, carpets, and furniture. These chemicals are commonly referred to as “thirdhand smoke”. The only method of reducing exposure is to avoid areas where secondhand smoke occurs, especially indoors.

Secondhand smoke exposure influences the physiological changes of the respiratory system. Clinical symptoms may vary depending on which physiological mechanism predominates and which anatomical region is most afflicted in a patient. The physiological reaction to secondhand smoke is similar to that of the smoker, but with a lesser impact. The changes that can be ruled out involve increased mucus secretion, decreased ciliary movement, increased white blood cell production, and increased mucosal permeability to foreign particles. These changes are correlated with the increase in total or specific immunoglobulin E (IgE) levels and the blood eosinophil counts in your body.

To some level, smoke can be a local irritant. The cells in the lungs mutate as a result of this prolonged irritation. They will easily learn how to keep evolving by altering, increasing, and re-growing the cells in the lungs. It is the persistence of the proliferation activities that can lead to cancer. Furthermore, smoking can affect and modify the DNA, resulting in cell multiplication, cancer, and continuing to spread as a consequence of cumulative changes over time.

Secondhand smoke causes several potential health risks. Secondhand smoke contains at least 250 hazardous compounds, including at least 50 carcinogenic elements (chemicals that are known to cause cancer). Vinyl chloride, cadmium, benzene, arsenic, and ethylene oxide are just a few of the toxic substances found in secondhand smoke. Cancer is reported to be caused by secondhand smoke around the whole world. The US Environmental Protection Agency has categorized it as a “known human carcinogen”. This has also been related to heart, and lung pathological conditions, as well as some other major health problems. According to statistics, nonsmokers who cohabit with a smoker have a higher probability of getting lung cancer than nonsmokers who do not live with a smoker.

While it seems to be the reason that more intensive or longer exposure to secondhand smoke is connected with a higher risk of developing medical issues, there is no acceptable limit for secondhand smoke exposure that has been determined. Secondhand smoke, even at low amounts, can be dangerous. This implies that wherever you go, any exposure to secondhand smoke should be avoided. This includes staying away from restaurants and pubs where smoking is still allowed nowadays. Open windows and using air ventilators do not eliminate all traces of secondhand smoke. However, they may aid in decreasing some of the toxins contained in tobacco combustion. It is encouraged to request people around you to refrain from smoking in your car or around your house.
