5. Summary of Data Reported and Evaluation
(N.B.: This section should be read in conjunction with the section
'General Conclusions on Hormones'.)
5.1 Animal carcinogenicity data
Since oestriol has not been adequately tested in experimental animals,
no assessment can be made.
5.2 Human carcinogenicity data
No case reports or epidemiological studies were available to the
Working Group. Epidemiological studies on steroid hormones used in
oestrogen treatment have been summarized in the section, "Oestrogens
and Progestins in Relation to Human Cancer", in this volume.
Subsequent evaluations: Vol. 21 (1979);
