Smoking is one of the leading causes of preventable death worldwide. It is responsible for a number of harmful medical conditions including heart disease, lung cancer, emphysema, and numerous others.
It is estimated that smoking cigarettes can shorten the average lifespan by as much as 10 years or more.
The Effects of Smoking on Health
There are many harmful chemicals in cigarette smoke that can have a serious impact on the health of the smoker, and even those around them. The majority of these chemicals are poisonous and can cause a variety of diseases and conditions.
One of the most serious effects of smoking is its link to cancer. In fact, smoking is responsible for about 25% of all cancer deaths globally. This includes not only lung cancer, but also cancers of the throat, mouth, bladder, pancreas, kidneys, and more.
Non-smokers who are exposed to secondhand smoke are also at risk, with an estimated 3,000 deaths per year from lung cancer alone.
Lung Cancer
Lung cancer is by far the most common type of cancer caused by smoking. It is a dangerous and often deadly disease that can be difficult to treat.
The American Cancer Society estimates that in the United States alone, there will be more than 228,000 new cases of lung cancer and more than 135,000 deaths from the disease in 2020.
Lung cancer occurs when abnormal cells in the lungs begin to grow uncontrollably, forming tumors that can spread to other parts of the body. Smoking is the leading cause of lung cancer, accounting for about 80% of cases.
Other Types of Cancer
Smoking is also linked to a number of other types of cancer. This includes cancers of the throat, mouth, larynx, esophagus, pancreas, liver, bladder, kidney, cervix, and more.
In fact, smoking is the cause of about 30% of all cancer deaths in the United States.
One of the biggest risks associated with smoking is the fact that it contains over 70 known carcinogens. These are substances that are directly responsible for the development of cancerous cells in the body.
Cigarette smoke also contains a number of toxic chemicals that can damage DNA and increase the risk of cancer.
The Importance of Quitting Smoking
Quitting smoking is one of the best things you can do for your health. It’s never too late to quit, and even people who have smoked for many years can greatly reduce their risk of cancer and other diseases by quitting.
Studies have shown that people who quit smoking can reduce their risk of developing lung cancer by as much as 50%. This risk continues to decrease over time, so the sooner you quit smoking, the better.
There are many effective methods for quitting smoking, including nicotine replacement therapy, prescription medications, and counseling or support groups. It’s important to find the method that works best for you and to stick with it.
Conclusion
Smoking is responsible for a significant amount of cancer mortality worldwide. It is the leading cause of lung cancer, and is also linked to a number of other types of cancer.
Quitting smoking is one of the best things you can do for your health, and can greatly reduce your risk of developing cancer and other serious medical conditions.
