The Cancer Data Service (CDS) is a data commons within the Cancer Research Data Commons (CRDC) infrastructure that brings expanded capacity and flexibility for researchers using the NCI data ecosystem. The CDS Portal is now live, giving researchers (like you) access to data storage and sharing capabilities for NCI-funded studies that fall into the following categories:

• Studies with data that do not match an existing CRDC data commons
• Studies with data that do not fit current data type criteria and/or the minimum metadata standards for a CRDC data commons

The CDS accommodates open- and controlled-access data from NCI projects and programs such as the Human Tumor Atlas Network, Division of Cancer Control and Population Sciences, and Childhood Cancer Data Initiative, making it even easier to search these data sets. It currently has study data from colorectal, lung, prostate, breast, ovarian, brain, and bone tumors.

Researchers can leverage the CDS Portal to search and browse data with no required login. This allows them to see if the CDS has data of interest before requesting access (in the case of controlled-access data). Finally, researchers can analyze data using one of the NCI Cloud Resources: the Seven Bridges Cancer Genomics Cloud powered by Velsera.
