How Smoking and Second-Hand Smoke Increase Lung Cancer Risk
When it comes to the causes of lung cancer, smoking is still the leading cause, but little do people know that second-hand smoke is just as lethal.
Whether you are an active smoker or somebody who inhales smoke from another person's cigarette, your lungs are continuously exposed to harmful chemicals that induce cancerous changes with time.
Cigarette smoke contains more than 7,000 chemicals, and at least 70 of those are known carcinogens-substances that directly damage the DNA in your lung cells.
All these toxins weaken the lungs' natural defense system, making it harder for the body to repair itself. Over time, this damage adds up, leading to uncontrolled cell growth-the beginning of lung cancer.
Even occasional smoking or exposure to smoke in closed spaces, like homes, cars, or workplaces, increases risk.
Second-hand smoke-the combination of smoke exhaled by smokers and the smoke from the burning end of a cigarette-contains the same toxic chemicals.
Studies show that nonsmokers who live with smokers have a 20-30% higher chance of developing lung cancer than those who do not.
The good news is that it's never too late to reduce your risk.
Your lungs can start to heal the moment you quit smoking, and avoiding secondhand smoke can drastically lower your chances of developing cancer.
