Breast cancer in young women 'increases risk' of disease in relatives

Dear all, I want to write a summary of a article very interesting.

You can enter in this link: http://www.guardian.co.uk/society/2010/sep/29/breast-cancer-young-women-risk

Well the article describe a studie of a group compose by parents and siblings of 504 womens diagnosed with the Breast cancer before the age of 35 and the scientist could to chek that this person had 1.5-2 fold increased risk of prostate, lung, brain and urinary cancers.

This risk increased when the scientist saw the faulty genes that increase the chance of breast cancer, for example if one of the abnormal genes is BRCA1 and BRCA2, the chance of had this disease is 55% to 85% risk of developing in their lifetime (the risk increased four-fold), being higher in siblings that in parents ,for example in mothers.
In contrast, women that dont have this abnormal genes, only account for between 2% and 5% of all breast cancers.

Is important to consider this study because suggesting a strategy to help identify other genes which significantly increase a woman's breast cancer risk, but this require new study for determine and confirm this risk and other genes.
Furthermore, previous studies have suggested the relation between the increased risk of other cancers and women with breast cancer, but the links have been weak and inconsistent.

Finally, Of the 504 women in the study, 41 had a BRCA mutation with a total of 2.200 parents and siblings were involved.

- Well, I have chosen this article beacuse It has a direct relation with my carrer, and I actually did not know what genes in particular are responsible of breast cancer and If its have relation with the developed of other cancers. With this information I can help of better way the women with this disease and prevent this in other women from young.

Thanks,
