Research: twins have an increased risk of cancer

Experts from the University of southern Denmark established the likelihood of cancer in identical and fraternal twins about a third above the normal threshold. In the study, researchers analyzed the health status of 200 thousand pairs of twins born in Sweden, Finland, Denmark and Norway in the period from 1943 to 2010.

During this time scientists have identified 3316 cases of cancer. Moreover, if one twin became ill with cancer, the risk of cancer in an identical twin was automatically increased by almost half and a third of the fraternal, says JAMA.

It is difficult to say why the twins there is initially an increased risk of developing cancer. Further studies should help answer this question.
