Lung cancer in non smokers is as real a threat as it is in smokers. What makes it worse is that while you, as a non-smoker, might make sure your life is healthy and without any vices, but being around smokers can cause much deadly damage to you, as it does to smokers!
Non smokers face a big risk of cancer from second hand smoke or environmental tobacco smoke. As a preventable cause of cancer, it is one factor that leads to many cancer-related deaths in the US. Roughly 3,000 deaths each year are attributed to cancer patients who have cancer due to second hand smoke.
Second hand smoke contains more than 4000 chemicals, 50 of which are believed to cause cancer. Inhaling this smoke, even inadvertently, can cause cancer. Just segregating sections is not enough as the air tends to still contain the harmful carcinogens despite not sitting with smokers.
Primary symptoms of lung cancer are usually easily identified.
If the cancer is more serious or more advanced, there could be other symptoms depending on which organ is affected like affected kidneys, liver or the brain.

Everyone is at risk if they prevail in an environment filled with cigarette smoke. There is no acceptable level in a smoke-free environment. Prevention is the best way to reduce exposure to second hand smoke.
Parents have to make sure that they are not around anyone who smokes. You have to also remember to not smoke in the house, not smoke when anyone is pregnant and generally take additional precautionary measures. Teach your child to stay away from smoke. Sometimes the carcinogens in the cigarette smoke also cling to the clothes of the smoker so just not smoking indoors might not help. If you have a history of cancer in the family it would help for you to stay away from smoking and smokers altogether.
Take simple steps like create good ventilation in the home, do not encourage people to smoke in the house and specify non-smoking facilities everywhere.
