Tumor Tissue Donation

I looked around in clinical trials for keywords like "genome", "microRNA", "tumor tissue", "tissue bank", "cell line", "dna", and of course "breast cancer".   You could also look for "NCI".   In looking for trials, look for NCI sponsored trial if possible. And ask for data sharing among researchers.

This one is creating cell lines from high risk breast tissue. if you had breast cancer before, your noncancer breast tissue might be immortalized! "To establish a repository (facility in which tissue samples can be preserved and stored for many years) of cell lines from high-risk breast tissue to allow researchers to learn more about changes in breast cells that may cause them to develop into breast cancer."
