1. Smoking Cigarettes: A Silent Predator

Smoking Cigarettes A Silent Predator

The act of lighting up a cigarette and inhaling its smoke remains the most significant contributor to lung cancer. It’s not just a bad habit; it’s a lethal one, responsible for the majority of lung cancer cases. Interestingly, cigarettes contain over 7,000 chemicals, many of which are proven carcinogens.

When you puff on a cigarette, you’re not just getting a nicotine hit. You’re filling your lungs with a toxic soup of chemicals. Each inhale leaves a residue on the delicate tissues lining your lungs, causing cellular changes that can be the first step on the path to cancer. Some of these toxins can remain in your body for years, continuing their destructive work long after you’ve stubbed out your last cigarette.

The numbers are equally startling. Compared to non-smokers, smokers are 15 to 30 times more likely to develop lung cancer or die from it. The risk isn’t just restricted to heavy smokers; even “light” smoking can double your risk. It’s no wonder why cigarettes are often called “cancer sticks.”

Chemicals like acetaldehyde, acrolein, and formaldehyde in the cigarette smoke interact with DNA in the lung cells, causing mutations. Over time, these mutations accumulate, and normal cells turn into cancer cells. The transformation is often slow but devastatingly effective, leading to different forms of lung cancer like small cell and non-small cell lung cancer.(1)
