The genetic test does not help to predict better a breast cancer as the American researchers have found out. Thus including of these tests in construction of model of forecasts of development of lethally dangerous disease will not lead to their larger accuracy.
Researchers from National institute of a cancer of the USA declare, that from the moment of introduction of the additional genetic information in medical cards of patients accuracy of forecasts concerning development of a cancer of a breast has not improved. Unfortunately, the latest achievements of a gene science have appeared meanwhile not too effective.

Americans used the information on traditional risk factors and also on 10 most widespread genetic indicators, collected about several thousand women at the age from 50 till 79 years. These ladies were objects of several researches in the USA and one large research in Poland. Two models of definition of risks - one with use for a long time already the factors taken into consideration, and another in addition with use of the genetic information have been used.

On the basis of the first model scientists could predict truly development of a cancer of a breast in 58 % of cases. When in model of construction of forecasts new genetic risk factors accuracy of the forecast has grown were added
