A number of studies that have been done show the relationship between smokers and fathers of childhood cancer, such as leukemia and brain tumors. The association was stronger in the presence of strong evidence of the results of the re-evaluation of research throughout the UK about childhood cancer conducted in the 1950s, according to researchers from the University of Birmingham, central England.
Their findings showed a highly significant correlation between fathers were smokers and the incidence of childhood cancer. One child of seven children with cancer may be related to defective sperm father caused by smoking.
The risk was increased in line with the increasing number of men smoke. If not given statistics smokers risk first, then 1.31 for light smokers and heavy smokers 1.42. Light smokers spend 10-20 cigarettes per day and heavy smokers spend more than 20 cigarettes per day.
Tom Sorahan, who led the study, said the results of this study have the same pattern with similar activities were done the year before.
Study were taken from the Oxford Survey of Childhood Cancers, comparing the lifestyles of 1:59 parents whose children who died of cancer between 1953 and 1955 with parents of healthy children in the same amount.
The findings add to a list of incriminating evidence that the father or mother because smoking can damage their children, say researchers. Laboratory studies show that the chemicals in cigarettes can cause damage to the genetic material in the sperm in the sperm which then lead to cancer.
