Changes in Blood Can Predict Cancer 13 Years In Advance
Small genetic changes that occur in our blood can show whether someone will be diagnosed with cancer in the next decade. Scientists at Northwestern University in the US They have discovered that changes in telomeres (the protective at the end of chromosomes that shrink as they age tapas) can show whether a person will go on to develop 13 years cancer before the first symptoms of the disease appear.
This first study of its kind shows that there is a unique pattern in telomere length that predicts what the chances of developing the disease are.
"Understanding this pattern of growth of telomeres may mean that there may be a predictive biomarker for cancer. We saw a strong relationship in the pattern across a wide variety of cancers, the right to test these procedures could be used to diagnose, finally, a wide variety of cancers. "He points the study's lead researcher Hou Lifang.
For the research needs of 792 healthy people were being observed in the period 1999 to 2012. At the end of this period, 135 of them were diagnosed with different cancers. Data analysis, scientists have discovered that they can predict who will develop cancer and which will not, looking at the pattern of changes in the length of telomeres in blood cells. From the outset, the telomeres of those who were later diagnosed with cancer were reduced much faster than those who were healthy. In fact, the telomeres of those who developed cancer in the future looked 15 years older than the telomeres of those who did not. .
