Smoking Causes Lung Cancer

For example, current studies have shown that the spouse of a smoker is likely to develop lung cancer. For women who have husbands who smoke, the risk is 20% that they will develop lung cancer.

For men whose spouses smoke, the risk is 30%. Also, those who are exposed to smoke in their place of employment are around 15% likely to develop lung cancer. These statistics are scary, and should cause concern to anyone who is exposed to smoke. Even someone who has never smoked has a risk of lung cancer from the smoke they are exposed to.

How Smoking Causes Lung Cancer

We know that smoking causes lung cancer. How does this process work? As previously noted, smoke from cigarettes has multiple carcinogens, or cancer causing materials, that are forced to enter your body when you smoke, or are exposed to smoke passively. These carcinogens damage the healthy cells in your lungs. These damaged cells can eventually become cancerous, given enough time. This effect is compounded over years, and is particularly noticeable in those people who smoke multiple packs of cigarettes a day.

But the sad fact is that those who are exposed to passive smoking, or secondhand smoke, are also in danger of developing lung cancer. While not as high of a risk as the actual smoker faces, continual exposure to lung cancer allows the body to inhale those carcinogens and causes damage to the lung cells. This can lead to lung cancer. Secondhand smoke is a very dangerous substance. You should avoid breathing smoke whenever possible. If you have children, keep them away from smoke at all times. Never allow people to smoke around your children, because their developing lungs are particularly susceptible to damage from smoke.

So if we know that smoking causes lung cancer, why is more not being done to stop the effects of smoking, and particularly second hand smoke? More and more cities are passing smoking bans, making it illegal to smoke in public locations such as restaurants. These steps are helping to reduce the number of problems relating to smoking and lung cancer, but much more needs to be done!
