Physician Cancer Reporting

It is required by state and federal law that all newly diagnosed cancer cases be reported.

Reporting Cancer Cases

In 1985 the California legislature enacted a law that established the California Cancer Registry (CCR), and since 1987, the California Health and Safety Code, Section 103885 has required hospitals, physicians, and certain other health-care providers to report all new diagnoses of cancer. Beginning January 1, 2001, diagnoses of borderline and benign primary intracranial and central nervous system (CNS) tumors are also reportable, as well as borderline ovarian cancer and certain hematopoietic diseases as described in the CCR Volume IV (Physician Requirements for Cancer Reporting in California).

Physicians must report diagnoses in those patients who do not undergo diagnostic procedures or treatment of their malignancies or brain tumors at a hospital or other cancer reporting facility in California. The Cancer Registry of Greater California (CRGC), operating under the authority of the Department of Public Health (CDPH), has the responsibility for abstracting the required data from the reporting physician’s records. Confidentiality of data collected is strictly maintained in accordance with the Health and Safety Code Sections 100330 and 103885; Civil Code, Sections 56.05 and 1798; Government Code Sections, 6250-6265; and Federal Law PL 104-191.

Reporting Requirements

Cancer diagnoses are reportable as soon as possible but not longer than six months after the date of initial diagnosis.

California Law does not require written or verbal patient consent to report, and specifically exempts physicians from any legal action or damages from meeting their legal obligation to report cancer cases or to provide access to those patient’s medical records.
