A new study reported from the Harvard School of Public Health concluded that smokers of long or ultralong cigarettes are at greater risk for lung and oral cancer than smokers of regular and king-sized cigarettes. They said “We found that smokers of long or ultralong cigarettes have higher concentrations of tobacco specific carcinogens in their urine than smokers of regular or king-sized cigarettes.”

Using data from the National Health and Nutrition Examination Survey from 2007 to 2010 the urine tests of 3,600 smokers of regular, king-sized, long or ultralong cigarettes were compared, Fifty three percent of the smokers used king sized cigarettes whereas smokers of long and ultra-long cigarettes comprised 31.5 percent and smokers of regular sized cigarettes comprised 15.4 percent¬† of the sample. There was significantly higher levels of NNAL, an indicator of tobacco specific carcinogen, in the urine of those smoking long or ultralong cigarettes than those smoking regular or king-sized cigarettes. They also found that older smokers, non-Hispanic blacks, and females had a greater tendency to smoke long or ultralong cigarettes. Researchers concluded that “This study indicates that there is an added risk to those smoking long or ultralong cigarettes.”

 

 

Does the Combination of Asbestos Exposure, Asbestosis, and Smoking Increase the Risk of Lung Cancer?

Wednesday, April 17th, 2013

logo1267406_mdIn an online publication of The American Thoracic Society’s American Journal of Respiratory and Critical Care medicine researchers concluded that the chances of developing lung cancer associated with exposure to asbestos, asbestosis, and smoking are dramatically increased when these three risk factors are combined, and smoking cessation significantly reduces the risk of developing lung cancer after long term asbestos exposure. Researchers said “In our study of a large cohort of asbestos-exposed insulators and more than 50,000 non-exposed controls, we found that each individual risk factor was associated with increased risk of developing lung cancer, while the combination of all three risk factors increased the risk of developing lung cancer almost 37-fold.” Results showed that in non-smokers asbestos exposure increased the risk of dying from lung cancer 5.2 fold, while the combination of smoking and asbestos exposure increased the death rate more than 28-fold and asbestosis increased the risk of developing lung cancer among asbestos-exposed subjects in both smokers and non-smokers, with the death rate from lung cancer increasing 36.8-fold among asbestos-exposed smokers with asbestosis. In addition, among insulators who quit smoking, lung cancer rates dropped in the ten years following smoking cessation from 177 deaths per 10,000 among current smokers to 90 per 10,000¬† among those who quit. The lung cancer rates among those who quit more than 30 years earlier were similar to those who never smoked.
