Lung cancer prevention


Lung cancer is the leading cause of death from cancer in the United States. In this kind of cancer, there is an uncontrolled growth of abnormal cells in the lungs that interferes with their function: to provide oxygen to the body through the blood. It is therefore easy to understand its consequences in the best case. By far, the biggest cause of lung cancer is smoking (cigarettes, pipes, or cigars), but its risk also is increased by exposure to secondhand smoke and to environmental factors (radon, asbestos, arsenic, and air pollution). It is very important to have in mind that risk of lung cancer can be reduced by quitting smoking and by eliminating or reducing exposure to secondhand smoke and environmental risk factors. Its treatment and prognosis will depend on the type (non-small cell lung cancer or small cell lung cancer) and how advanced it is.

It is also important to know that it has been shown that DHA and EPA have anti-proliferative effects in a type of human lung cancerous cells, called A549 cells. So, they have potential in the prevention or treatment of lung cancer.

However, the best way to prevent is not to smoke. And, if you are already a smoker, you must know that stopping smoking will reduce your risk of lung cancer compared to continuing to smoke. It’s never too late.
