Cal. Health and Safety Code § 104880

The department shall identify at least one program for screening and follow-up care for each health service area for purposes of referral of persons exposed to diethylstilbestrol while pregnant or prenatally. The department shall consider the provider’s compliance with state- and federally-mandated standards, the location in relation to the geographical distribution of persons exposed to diethylstilbestrol, and the capacity of the provider to properly screen for breast cancer, vaginal cancer, cervical cancer, vaginal adenosis, and any other malignancy and abnormal conditions resulting from exposure to diethylstilbestrol. The department shall designate existing facilities presently serving the diethylstilbestrol-exposed population as screening programs pursuant to this section. However, if existing facilities are not available, training for screening and follow-up may be offered to the personnel in existing facilities and clinics.
