Studies show that twins risk to cancer

According to a study conducted in the United States, Miami has made study of 200,000 people found that twins shared a common gene and when one of them with cancer, the other twin will have a high risk to the disease as well.
But based on reports in the journal Medical Association of America (Journal of the American Medical Association) has confirmed that, despite the twins born has also not sure implicitly that the other twin will have the same cancer. In fact, the percentage of increase in risk of cancer is only 14% higher than for the twins that someone diagnosed with cancer .

Twins (Identical twin) are evolving from single embryos and distribute jointly rlek genetic factors. For fraternal twins (fraternal Twins), which has evolved from two different embryos and have similar genetic factors have a higher risk of 5% .

Twin choosing to study the subject is chosen from Denmark, Switzerland and Norway, and they were followed health between 1943 and 2010.

When researchers examined a group one, they found that one in 3 cancers (32%). So the risk of cancer of the twins were diagnosed and 46 percent calculation.

Fraternal twins is 37% risk of recurrence of cancer if co twin was diagnosed. For cancer, the same cancer diagnosis is 38% for twins and 26% for fraternal twins.

Most cancers observed incidence of twins, 5 percent of skin cancer, prostate cancer, 57%, 43% cancer non melanoma skin cancer, kidney 38% , breast cancer, 31%, 27% of kidney cancer bloodless.

According to his author Jacob Hjelmborg processing business jointly led the study from the University of Southern Denmark, said, "Because of the size and duration of study followed for a long time now, we can know that cancer can be caused by genes. "

Researchers said the findings could help patients and doctors to better understand the risk of cancer due to heredity factors that it is a disease usually kills 8 million people worldwide each year.
