This extended follow-up will collect
information to assess whether over-diagnosis - the identification
of cancers with little-to-no clinical felevance through screening -
occurs with lung cancer screening. To that end, the participants in
the Mayo Lung Project (MLP), a large randomized controlled cancer
screening trial of chest x-ray and sputum cytology conducted in the
1970s and 80s will be contacted and asked about lung cancer
diagnoses since the close of the Project (July 1983).
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).

the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
