Hi Susan,
Welcome to the online network, we are very glad you found your way to and around the site.
You may find the site-wide search helpful in finding information on Triple Negative breast cancer. I have just completed a search and it returned over 30 pages, which includes other member blog posts and pages from the BCNA website.
You can follow the link to view the results: http://www.bcna.org.au/search/node/Triple%20negative
You might also find the 'Help' section of the website a great way to get started and find out about the site and its different features.
Good luck and if you have any questions don't hesitate to ask.
Daina
