7 Warning Signs of Lung Cancer You Shouldn’t Ignore

7 Warning Signs of Lung Cancer You Shouldn't Ignore 

Lung cancer is among the most common types of cancers in both men and women worldwide. 

According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. will be diagnosed with lung cancer at some point in their lifetime. In the U.S., lung cancer has surpassed breast cancer as the most common cause of cancer-related deaths in women. But being aware of the risk factors and paying attention to warning signs and symptoms can save life.

Risk factors

  • Smoking – There is a strong link between lung cancer and cigarette smoking, and about 90% of lung cancer cases are a result of tobacco use. The risk of lung cancer increases the more cigarettes you smoke and the longer time you smoke. It is believed that among smokers of two or more packs of cigarettes per day, one in seven will die of lung cancer.
  • Passive smoking – You don’t have to be a smoker yourself to put your health at risk. Tobacco smoke contains many chemicals that have been shown to be carcinogenic. The risk increases the more you are exposed to cigarettes smoked by the other people.
  • Air pollution – It is believed that prolonged exposure to highly polluted air can increase the risk of developing lung cancer similar to that of passive smoking.
  • Asbestos fibers and other chemicals - asbestos use is limited or banned in many countries, but was widely used in the past. This includes also exposure to certain chemicals and substances that are used in several occupations and industries such as arsenic, beryllium, cadmium, coal, silica and nickel.
