The Ontario Tumour Bank (OTB), a province-wide biorepository and data bank led by the Ontario Institute of Cancer Research (OICR), has banked samples from more than 10,000 donors, which is an important milestone for the OTB. Samples collected by the OTB help cancer researchers to analyze cancer at the genetic and molecular level and they are essential to help map the genomic changes present in many forms of cancer. This will help to build the next generation of diagnostic tools and treatments for cancer, including more personalized medicine. For more information, please visit www.ontariotumourbank.ca.
