Cancer became a reportable disease with the enactment of Health and Safety Code, Section 103885 in 1985. The California Cancer Registry (CCR) has gathered information on all cancers diagnosed in California since 1988. (The only exceptions are basal and squamous cell carcinoma of the skin and carcinoma in situ of the cervix.)
All information collected by the CCR are considered confidential based on section 103850 of the Health and Safety code. Persons with a valid scientific interest who are engaged in demographic, epidemiological or other similar studies related to health who meet qualifications as determined by the California Department of Public Health, and who agree, in writing, to maintain confidentiality, may be authorized access to confidential information.
