The SEER Inquiry System (SINQ) is a searchable collection of questions that cancer registrars have had while coding cancer cases. These are questions submitted by designated registrars in SEER registries. The questions are answered by expert staff and go through a rigorous review process by NCI SEER staff and designated SEER registry staff before being added to SINQ.
