If the biopsy is for clinical analysis, the answer is generally yes. If it's a research biopsy, it depends on the type of research and the institution. Biomarker studies may or may not be shared; correlative studies are generally not shared.
So, here we come full circle. This entry began with the question of whether you should consent to a research biopsy. Now that you have more information, I'd like to turn that question around.
