Health care providers, clinical laboratories, and hospitals are required by Connecticut statute (Chapter 368a, Section 19a-72) to report all cases of malignant tumors (and associated conditions) to CTR.  Timelines for reporting and civil penalties associated with failure to report are described in the statute.  Facility reporting to CTR does not violate HIPAA regulations.
