I found some information on lung cancer from the Lung Cancer Research Foundation. This could be very helpful to you and me. Sharing with you some key information below on the risk factors of this disease. Read on:
1. Tobacco – There is clear-cut evidence of the link between tobacco use and lung cancer. The number of tobacco-related lung cancers is 90% for men and 78% for women in the US. People who stop smoking can lower their risk of this disease. Second-hand smoke or passive intake also increases the risk of getting this disease.
2. Environmental causes – Although there are numerous specific agents, their impact is lower than smoking. Causes include asbestos, radon, arsenic, chromium, nickel, tar and soot. Pollution may be a cause of this disease. Cities with higher pollution rates have higher numbers of lung cancer cases.
3. Beta-carotene – Studies show heavy smokers who take beta-carotene supplements have higher rates of lung cancer than those who do not.
Take note also of these warning signs for lung cancer that you should discuss with your doctor: persistent cough, chest pain, weight loss and/or decreased appetite, bloody sputum, shortness of breath, hoarseness, fever for unknown reasons, recurrent infections such as bronchitis or pneumonia. Should you or your loved ones experience these symptoms, see you doctor right away.
