The state of Missouri currently has 98 active clinical trials seeking participants for Breast Cancer research studies. These trials are conducted in various cities, including Saint Louis, Kansas City, St. Louis and Springfield.
National Cancer Institute "Cancer Moonshot Biobank"
Recruiting
This trial collects multiple tissue and blood samples, along with medical information, from cancer patients. The "Cancer Moonshot Biobank" is a longitudinal study. This means it collects and stores samples and information over time, throughout the course of a patient's cancer treatment. By looking at samples and information collected from the same people over time, researchers hope to better understand how cancer changes over time and over the course of medical treatments.
