How Lung Cancer Develops

When scientists and doctors talk about the myriad of diseases smoking causes, lung cancer is foremost among them. Lung cancer is usually the result of smoking tobacco and is not usually related to the electronic cigarette UK. But what exactly causes lung cancer, and how does it spread? Before examining the statistics and data, it might be useful to define what lung cancer is. Lung cancer occurs when there is abnormal cell growth in lung tissue. This growth, if not treated, can spread to surrounding tissues and organs in a process called metastases, and can lead to a number of adverse side effects, including death.

Experts estimate that between 80-90 percent of all lung cancer cases develop due to consuming tobacco products. Research from The Centers for Disease Control (CDC), an United States health agency, has shown a decrease in the instances of lung cancer. Interestingly, there has also been a decrease in tobacco consumption. Other catalysts for lung cancer include exposure to radon gas, asbestos or air pollution, which includes second hand smoke. Genetics may factor into the picture as well.

Lung cancer is caused when the DNA of a patient is damaged, which can lead to abnormal cell growth. The body’s DNA contains mechanisms that regulate and control cell growth, and when the DNA is damaged, these can be affected. There are two main types of lung cancer: small-cell lung carcinoma, and non-small cell lung carcinoma. Some common side effects of lung cancer include respiratory effects, such as coughing up blood and trouble breathing. Other effects include weight loss, fever and chest pains.



The mortality rate for lung cancer patients is not good. It is estimated that only 15 percent of lung cancer patients live more than five years after diagnosis. In many cases, by the time a conclusive diagnosis is reached, the cancer has advanced to Stage IV.

The best way to prevent developing lung cancer is to not consume tobacco products, or quit if one already does. As mentioned earlier, a connection exists between the decreasing instances of lung cancer and the decline in smoking cigarettes. Some have stated that diets rich in fruits and vegetables can decrease the chance of developing lung cancer, and while this is a good health habit overall, no studies have conclusively determined if it really does prevent lung cancer. Screenings, such as CT scans, by health professionals, can potentially catch lung cancer before it spreads.

Lung cancer is a serious health concern in our world, but with some changes to health habits, it can be easily prevented.
