According to a new research, high doses of certain vitamins of group B connected to the increased risk of lung cancer in smoking men.
The study was conducted by the scientists from the Arthur G. James Cancer Hospital and Richard J. Solove Research Institute at the University Comprehensive Cancer Center (OSUCCC) in Columbus, USA, with the Fred Hutchinson Cancer Research Center in Seattle, USA, and National Taiwan University in Taipei.
The researchers reviewed data from 77,118 people between 2000 and 2002 when participants were aged from 50 to 76. Every person gave information concerning the use of vitamin B over previous 10 years.
Having analyzed the collected data, the researchers concluded that male smokers taking 20 mg of Vitamin B-6 daily for 10 years were 3 times more likely to go on to develop lung cancer, and those male smokers taking 55 mg of Vitamin B-12 daily for 10 years were about 4 times more likely to develop the condition.
