Hi Pam,
Ann-Marie here from the BCNA Online Network team.
Thank you for sharing this post. I agree totally with the importance of cancer research in developing new or improved treatments as well as the importance of international collaboration.
A lot of the research is conducted collaboratively between researchers in different countries, and those results are shared in journals, at international conferences, etc.
If you are interested in finding more information about how breast cancer clinical trials are run, our Clinical Trials fact sheet provides more info.
