For decades now, it has been no secret that smoking is one of the most devastating habits to the human body. There aren’t many things that can do more damage to our bodies than cigarettes. However, out of all health risks associated with smoking, lung cancer is the most vicious one. Unfortunately, due to the frequency of smoking habits, lung cancer cases are still one of the most rampant forms of cancer globally.
Without any second thought, smoking is a sure way to cause cancer. And lung cancer is the most common out of all the ones that smoking contributes to. However, you are in luck because unlike other forms of cancer, early intervention and diagnosis can offer a higher probability of treatment. In this article, we take a look at how smoking contributes to the development of lung cancer and the impact that this disease holds on the life of suffering individuals.
Lung cancer is not only harmful to the smoker but also to the people surrounding them. Once inhaled, the toxic chemicals from smoking will reach the lungs and become held up. The primary role of our lungs is to supply oxygen to the body. Instead, smokers expose themselves to a wide range of chemicals that are not suitable for human consumption. These chemicals then cause abnormal growths in lung tissues, which eventually results in cancer. And the long-term effects of smoking become increasingly worse with time.
Types of Lung Cancer
Lung cancer is a deadly disease that affects millions of people worldwide. It is a type of cancer that starts in the lungs and can spread to other parts of the body if left untreated. There are two main types of lung cancer: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). While both types of lung cancer are associated with smoking, NSCLC is the most common type and makes up about 85% of all lung cancers.
- Small Cell Lung Cancer (SCLC): This type of lung cancer is very aggressive and tends to spread quickly, making it more difficult to treat. About 10-15% of all lung cancers are SCLC.
- Non-Small Cell Lung Cancer (NSCLC): NSCLC is the most common type of lung cancer and is further classified into three subtypes: adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Adenocarcinoma is the most common subtype and accounts for 40% of all lung cancers. Squamous cell carcinoma accounts for about 25% of all lung cancers while large cell carcinoma accounts for 10-15% of all lung cancers.
NSCLC is further classified based on the size and location of the tumor, as well as the type of cell that the cancer originates from. Adenocarcinoma, for example, affects the cells that produce mucus in the lungs, while squamous cell carcinoma affects the flat cells that line the airways in the lungs. Large cell carcinoma, on the other hand, affects the cells in the outer parts of the lungs.
It is important to note that while smoking is the leading cause of lung cancer, other factors such as exposure to radon, air pollution, and a family history of lung cancer can also increase the risk of developing lung cancer. Therefore, it is crucial to take precautionary measures and quit smoking, as well as get regular checkups to catch any potential signs of lung cancer early on.
Smoking and Lung Cancer
It is no secret that smoking is the leading cause of lung cancer. According to the American Lung Association, smoking is responsible for about 80% of all lung cancer deaths in the United States.
- Cigarette smoke contains more than 70 known carcinogens, or cancer-causing agents. When these chemicals are inhaled, they can damage the cells that line the lungs, leading to mutations that can eventually turn cancerous.
- Not only does smoking increase the risk of developing lung cancer, it also makes the cancer harder to treat. Smoking weakens the immune system, making it harder for the body to fight off cancer cells.
- Even secondhand smoke can increase the risk of lung cancer. Those who regularly breathe in secondhand smoke are about 20-30% more likely to develop lung cancer than those who do not.
It is important to note that smoking can also increase the risk of developing other types of cancer, including throat cancer, pancreatic cancer, and bladder cancer, among others. Quitting smoking can greatly reduce the risk of developing these cancers, as well as improve overall health and well-being.
If you are a smoker, it is never too late to quit. Talk to your healthcare provider about resources that can help you quit smoking and reduce your risk of developing lung cancer and other health problems associated with smoking.
| Type of Lung Cancer | Percentage of Cases Associated with Smoking |
|---|---|
| Non-Small Cell Lung Cancer (NSCLC) | 85% |
| Small Cell Lung Cancer (SCLC) | 95% |
As the table above shows, both types of lung cancer are heavily linked to smoking. Non-small cell lung cancer is the most common type of lung cancer, accounting for about 85% of cases. Of those cases, about 85% are associated with smoking. Small cell lung cancer is less common, accounting for only about 15% of lung cancer cases, but is even more strongly associated with smoking, with about 95% of cases linked to smoking.
Symptoms of Lung Cancer
Early detection of lung cancer is crucial to increase the chances of successful treatment. The symptoms of lung cancer can be quite subtle in the beginning, but they can worsen as the disease progresses. It is essential to know the usual signs of lung cancer, especially if you are at an increased risk.
