ATM genetic testing helps predict breast cancer

A recent British study found that the status of an ATM gene is linked to the risk of human breast cancer.

>>>New findings on level 3 negative breast cancer

By blood test, scientists can know the abnormal changes of this gene many years before they develop into breast cancer.

This gives hope in the future that may develop methods to predict the risk of breast cancer.

Medical studies show that different versions of the gene in the human body will lead to a different risk of disease, and the condition and function of the gene will also change due to a number of reasons.

Therefore, through the examination of specific gene status to diagnose the corresponding risk of disease, is one of the hot spots of medical research.

British Imperial College London researchers have published in the latest issue of Cancer Research magazine that they have studied the health records of more than 1300 women - who are periodically taking blood samples in one or The last two decades have found that more than 600 people later have breast cancer.

Analysis shows that, among people with breast cancer, the majority of people who have been sick for many years, have a gene called ATM with an abnormal condition called Methyl . Conducting a leukocyte test in blood samples can know the methylation level of this gene.

In women with the highest levels of ATM methylation, the risk of breast cancer later accounted for 89% of the lowest women.

Even women have appeared the status of ATM methylation 11 years before developing the disease.

Dr. James Flanagan said that the current change of a gene is linked to the risk of breast cancer, the next step is to study the entire genome to find more relevant genes.

Hopefully in the future, on this basis, there may be many measures to predict the risk of breast cancer through blood tests.
