Thinner smokers get higher risk of lung cancer: research

A recent research showed that thinner smokers have a higher risk of lung cancer than their fatter counterparts, local media reported on Wednesday.
Researchers from the National University of Singapore surveyed 63,257 middle- aged and elderly Chinese Singaporeans from 1993 onwards. It examined the relationship between smokers\’ body mass index (BMI) – a measure of obesity – and their chances of lung cancer, local English newspaper the Straits Times reported.
The research found that pack-a-day smokers with a BMI of at least 28 were six times as likely to get lung cancer as equally heavy people who had never lit up.
But thinner pack-a-day smokers, who had a BMI of less than 20, were 11 times as likely to get the disease as non-smokers of a similar weight and BMI.
Lung cancer is the second most common cancer in men in Singapore, and the third most common in women.
