The record
An earlier report raising talc and ovarian/cervical carcinoma appeared in 1971.
Claim scope
That the talc-ovarian question was in the peer-reviewed literature by 1971, twenty-one years before the memo. Title, journal, year, volume and pages verified via the PubMed record.
What this source does not establish
No abstract is available in the PubMed record and I did NOT read the full text. I therefore cannot state what it measured, what population it studied, or whether it reported any quantitative risk measure. Do not attribute any finding or number to it.
Limitations
Cite only as 'a 1971 report in the Journal of Obstetrics and Gynaecology of the British Commonwealth raised the question' — nothing more. Abstract unavailable; full text not obtained. If the page needs to characterize its content, the full text must be retrieved first.
