I.1.6.1 Definition of Cancer

Cancer is defined by the Health and Safety Code for registry purposes, as "all malignant neoplasms, regardless of the tissue of origin, including malignant lymphoma, Hodgkin Disease, and leukemia, but excluding basal cell and squamous cell carcinoma of the skin."

January 1, 2001 and Forward

Effective with cases diagnosed January 1, 2001, benign and uncertain behavior intracranial and central nervous system (CNS) tumors became reportable along with newly reportable histologies published in ICD-O-3. Although borderline ovarian tumors changed behavior in ICD-O-3 from /3 (malignant) to /1 (borderline), the CCR will continue to require reporting them. They are to be coded with a behavior code of /1. The CCR establishes an official list of reportable neoplasms annually. A tumor must be reported if it is diagnosed as cancer by any physician (including a pathologist or radiologist), surgeon, or dentist.

January 1, 1996 and Forward

Effective with cases diagnosed January 1, 1996, carcinoma in situ (including squamous cell and adenocarcinoma) of the cervix and CIN III (cervical intraepithelial neoplasia, grade III) are no longer reportable to the CCR.
