When people think of lung cancer, they often associate it with smoking tobacco. However, it is important to note that anyone can develop lung cancer, regardless of their smoking history. Research has shown that there are other risk factors for lung cancer besides smoking, such as exposure to secondhand smoke, occupational exposures, radon and air pollution, and genetic factors. In this article, we will explore the percentage of lung cancer patients who have never smoked and provide an overview of the findings from a study conducted by the American Cancer Society and the US Centers for Disease Control and Prevention.
Overview of the Study
The study conducted by the American Cancer Society and the US Centers for Disease Control and Prevention aimed to gather data on lung cancer patients in the United States who had never smoked. Unlike previous studies that relied on small population sizes from hospital data, this study utilized population-based data from multiple state cancer registries, allowing for a larger sample size and more accurate results.
Smokers and Former Smokers
According to the study, more than 84% of women and 90% of men diagnosed with lung cancer were either current or former smokers. Among patients aged 20 to 64, half of them reported currently smoking. For patients aged 65 to 79, approximately 86% to 91% had smoked at some point in their lives or were still smoking. The study also found that the proportion of current smokers was higher among Black individuals compared to White or Hispanic individuals with lung cancer.
Never Smokers
Surprisingly, the study revealed that almost 16% of women and nearly 10% of men diagnosed with lung cancer had never smoked. Out of over 129,000 lung cancer patients, 15% of both men and women had never smoked. The highest number of never smokers was found among individuals aged 20 to 4Additionally, the study found that more women who developed lung cancer had never smoked compared to men. Furthermore, patients diagnosed with adenocarcinoma of the lung had a higher proportion of never smoking compared to those with small cell or squamous cell carcinomas of the lung.
Limitations of the Study
It is important to note that the data included in the study were only from states and years where the status of cigarette use was known for less than 15% of cases. Therefore, the findings may not represent the entire population of lung cancer patients who never smoked.
While smoking remains a significant risk factor for lung cancer, it is essential to acknowledge that a considerable percentage of lung cancer patients have never smoked. This study provides valuable insights into the demographics of lung cancer patients who have never smoked, highlighting the need for further research into other risk factors and potential causes of lung cancer. By better understanding the various factors contributing to lung cancer, we can improve prevention strategies, early detection, and treatment options for all individuals affected by this devastating disease.
