London - breast X-rays, aimed at discovering may actually increase the breast cancer gene in young women the opportunity to develop a higher risk of their disease, and studies have shown that one of the leading European Institute of Oncology.
Increase breast X-rays and other types of the test chest radiation radiation may be harmful to them, and MRI may be a safer way, because the gene mutation screening women under the age of 30 who are at high risk of draw conclusions.
The study can not prove the link between radiation and breast cancer, but it is one of the largest-ever look at the issue. The study, published Thursday in the journal the BMJ.
This will raise the problem of how we treat women (gene) mutation and Precautions flag, said: "Dr. Len Lichtenfeld, the American Cancer Society, deputy chief medical officer he and society does not have any role in the study.
X-rays of the breast is the most commonly used in women over the age of 40, unless they are at high risk, such as carrying BRCA1 or BRCA2 gene mutations. This mutation increases five times the risk of cancer. About 400 women have a genetic abnormality, which is more common in Eastern European Jewish residents. Different breast X-rays, MRI, or magnetic resonance imaging scans, and does not involve radiation.
Breast cancer screening test has proven to save lives, the average risk of breast cancer in women over the age of 50 is clearly beneficial. The expert disagreement its value in women under the age of 50.
Some studies have shown that women with genetic mutations in the gene may be more sensitive to radiation because the issues involved in the repair of DNA. If these genes radiation damage, they may not be able to properly repair DN A, increase the risk of cancer.
In some European countries, including the United Kingdom, the Netherlands and Spain, the doctors have recommended that women with BRCA mutations before the age of 30, magnetic resonance imaging instead of X-rays of the breast. In the U.S., there is no specific advice from a leading government adviser Task Force, the American Cancer Society recommends annual breast X-rays and magnetic resonance imaging of the women from the 30-year-old BRCA gene mutation.
