However, to prove the possibility of genetic susceptibility in relation to any survival difference across type of breast cancer molecular genetic studies such as BRCA1 and BRCA2 in association with survival, although the results are inconsistent (Moller et al, 2007; Rennert et al, 2007; Tutt and Ashworth, 2008), are still required. Here, BRCA1 is linked to breast carcinoma.
