Many thanks for the valuable contribution to the breast cancer word.

You have written the following description in the Introduction:" ..other 90–95% is assumed to be 'sporadic', with no apparent family history. A large proportion of familial breast cancer (<40%) can be attributed to mutations in the high-risk genes BRCA1 and BRCA2 [1]".

My comment: the sporadic figure of 90%-95% doesn't indicate that the proband has no family history.There are many families in my database having 3-8 and 4-12 relatives affected with Breast cancer and other malignancies, respectively, who had no mutation in BRCA1&2.So, Familial BC is not representive of inherited BC. Many of our early onset probands with no family history could be positive ( i.e.,inherited, or new mutation)or negative for BRCA-genes.

Many thanks

Competing interests

The global movement for achieving more complementary data on the Gentic aspects of breast cancer patients required the followings:

-Linking between available datas from different populations in the world.

-Creating a core for discussion between the scientists who are actively involved in breast cancer resaerch.

Thanks
