Approximately 85-90% of lung cancer cases are attributed to smoking. Smoking is the leading cause of preventable deaths worldwide and is responsible for various health issues, with lung cancer being one of the most significant consequences. To provide a more detailed answer, let’s look into this topic further.
According to the World Health Organization (WHO), smoking tobacco is “the single most important factor for the development of lung cancer.” The harmful chemicals present in tobacco smoke, such as carcinogens and toxins, damage the cells in the lungs and other parts of the respiratory system, leading to the development of cancerous tumors.
Here are some interesting facts about the correlation between smoking and lung cancer:
Risk Factor: Smoking is the primary risk factor for developing lung cancer, accounting for the majority of cases. Other factors, such as exposure to secondhand smoke, asbestos, radon, air pollution, and certain genetic predispositions, can also contribute to the development of the disease.
Relative Risk: Smokers are estimated to be 15-30 times more likely to develop lung cancer compared to non-smokers. The risk increases with the number of cigarettes smoked per day and the duration of smoking.
Secondhand Smoke: Secondhand smoke, also known as passive smoking or environmental tobacco smoke, is a known cause of lung cancer in non-smokers. It is estimated that exposure to secondhand smoke increases the risk of developing lung cancer by about 20-30%.
Quitting Smoking: Quitting smoking significantly reduces the risk of developing lung cancer over time. According to the American Cancer Society, within 10 years of quitting, the risk of lung cancer drops by about half compared to someone who continues to smoke.
Now, let’s include a relevant quote from a well-known resource to emphasize the significance of smoking in relation to lung cancer:
“In the United States and many other countries, cigarette smoking is the leading cause of lung cancer. It is also a risk factor for cancers of the mouth, throat, voicebox (larynx), esophagus, bladder, kidney, pancreas, cervix, stomach, and some leukemias.” – American Cancer Society
Lastly, let’s provide a table highlighting smoking as a significant contributor to lung cancer cases:
| Lung Cancer Cases (%) | Causes |
| 85-90% | Smoking |
| 10-15% | Other Factors |
Please note that the table above is for illustrative purposes only and percentages may vary slightly in different sources.
Overall, it is crucial to raise awareness about the strong association between smoking and lung cancer. Preventive measures, such as anti-smoking campaigns, education, and support for smoking cessation, can play a pivotal role in reducing the burden of lung cancer and improving public health.

In the United States, cigarette smoking is linked to about 80% to 90% of lung cancer deaths. Using other tobacco products such as cigars or pipes also increases the risk for lung cancer. Tobacco smoke is a toxic mix of more than 7,000 chemicals. Many are poisons.
This number would be higher for those who have smoked and lower for those who have never smoked. Cigarette smoking is responsible for 80% to 90% of all lung cancer cases, making it the top cause of the disease. 2 And those who smoke are as much as 30 times more likely to get lung cancer than those who don’t. 3
In the United States, about 10% to 20% of lung cancers, or 20,000 to 40,000 lung cancers each year, happen in people who never smoked or smoked fewer than 100 cigarettes in their lifetime. Researchers estimate that secondhand smoke contributes to about 7,300 and radon. to about 2,900 of these lung cancers.
Worldwide, 15–20 percent of men with lung cancer are non-smokers while over 50 percent of women with lung cancer are non-smokers.11This demographic has some significant geographic differences as lung cancer in non-smoking women in Asia comprises approximately 60–80 percent of the cases of lung cancer.12In a study performed in the United States, roughly 19 percent of women with lung cancer were non-smokers, and only 9 percent of men with lung cancer were non-smokers.13As this data has
The good news is that the risk of having lung cancer and other smoking-related illnesses decreases after you stop smoking and continues to decrease as more tobacco-free time passes. The risk of lung cancer decreases over time, though it can never return to that of a never smoker.

In the United States, cigarette smoking is linked to about 80% to 90% of lung cancer deaths.

An expert from Florida Cancer Specialist debunks five common myths about smoking and lung cancer. Firstly, quitting smoking years ago does decrease the risk of lung cancer, but not to the level of a never smoker. Secondly, non-smokers can indeed get lung cancer, especially women exposed to second-hand smoke. The potential link between medical marijuana and lung cancer is still inconclusive. Contrary to the myth that there is no effective screening method, low dose CT scans have shown a 20% decrease in mortality. Lastly, early detection significantly increases the chances of a cure, with a 65% cure rate for stage one cancer through surgery. Being aware of these myths and taking precautions is essential for protecting one’s health.
