Hi Mandy and welcome,
I am so sorry to hear that your friend has been dx with TNBC, but you definitely have found the site for information which will help her.
Did you friend's sister ever have the BRCA testing? If not they both should now. 85% of BRCA1 gene mutations are TNBC. Here is a link for the FORCE website, and there is much information which may help your friend.
I will have to ask Pam to pull up the link for the teleconference, or maybe someone else will be able to tell you how to find that. In the meantime I will send you a private message with my email so that I can send you information for all the resources here on the site.
Many hugs,
Nancy
