An analysis of 13 previous studies, involving thousands of men, found that every extra two inches in height raises the odds of the disease by 13 per cent. It is not yet known what is behind the link, but it may be that the hormones involved in growth help fuel the disease.
Testicular cancer affects some 2,000 men in UK a year and, unlike other cancers, it is most common in the young. Half of cases occur in mens under age of 35, with those aged 25 to 34 are the most likely to be affected.
It is one of the most easily treated forms of the cancer disease, with survivors including seven-times Tour de France winner Lance Armstrong and Grand National-winning jockey Bob Champion.
US researchers made the link with height after crunching together data from more than ten studies from around the world. Researcher Dr Michael Blaise Cook,Writing in the British Journal of Cancer, said that genes, nutrition, hormones and other factors that affect height may also play a role in the cancer.
But British cancer experts urged tall men not to worry, saying that the cancer is relatively rare.
