The results of scientific research indicates tall people more at risk to develop ten types of common cancers, including colon, breast, kidney, and brain. Scientific research is to monitor the 1.3 million middle-aged women in Britain in the period between 1996 and 2001.
The research, published scientific journal Lancet Oncology found that for every increase of 10cm above the height 152.4 cm, female cancer risk rose 16%.
Dame Valerie liberal, director of the Epidemiology Unit of Oxford Epidemiological who conducted the research, said,''16 percent is fairly constant for all types of cancer.''
According to the liberal, the same thing also occurs in men and around the world. However, he stated the researchers do not yet know the cause of increased cancer risk.
The main theory about the link between height and cancer risk drawn to growth hormone.
The researchers suspect, but can not prove that the growth hormones, including insulin-like growth factor - may be the cause. The higher the growth factor, perhaps the higher rate of cell division and regeneration, and it increases the risk of cancer.
The researchers say tall people do not have to worry, because the impact is relatively small stature compared to other factors.
Clinical oncology expert Dr Tom Powles at the cancer center of Saint Bartholomews in London said,''The relative risk, the risk increased when compared with things like smoking, is actually very small.''
Overweight or obesity is also a bigger factor in cancer development, researchers say.
According to them, an increase in Body Mass Index of 10 points increases the risk of breast cancer by about 40%.
