A lot has been said that active and passive smoking is not good for health, it has been recently revealed through a research that men pass on toxic substances of tobacco products through their genes to their children.

This passage will result into increased risk of cancer among children as well as increase the danger of damaged genes. "Smoking by fathers at the time around conception can lead to genetic changes in their children. These changes may raise the risk of developing cancer", said Diana Anderson, who was working on the project, from the University of Bradford.

Study researchers were of the view that toxic substances pass through the semen and disrupt the DNA formation of child and can make him susceptible to cancer. Diana has advised that fathers should not smoke at the time when their partners have conceived.

In addition, another research being taken out by a group of researchers from the University of Glasgow has found that men, who are tea-lovers, are at high risk of being affected by prostate cancer. The study researchers further specified that people, who consume more than seven cups a day, are at an increased risk of 50% to contract the disease.
