Women with mutations in a gene called Brca1 tend to develop this kind of aggressive breast tumor. Patterns of genetic activity of these tumors are careful through special tests because what the biological tests reveal turn out to be quite different from what the gracious eyes perceive. Researchers used new techniques of molecular biology to determine the patterns of gene activity in the crabmeat cells and then to classify and sort the subtypes by lam. Further research is on to find an alternative to chemformer(a)apy.
