The purpose of this paper is to trace the American Society for the Control of Cancer's (ASCC) influence on the Portuguese Institute of Oncology's (IPO) Bulletin. The time period featured is from 1934 to 1940, which spans the first two decades of the newly formed Portuguese dictatorship, known as the Estado Novo (1933–1974). The analysis of the ASCC's “imprint” on the IPO's Bulletin aims to shed new light on how American culture influenced Portugal, from its first appearance at the beginning (...) of the 20th century. It brings together the disciplines of history of science and history of art and visual studies, in order to analyse these campaigns' strategic relationship with their “patients and contributors to be.” The public is encouraged by this means not only to seek timely assistance, but also to participate financially in the “cancer cause.” This is achieved by means of international consumer culture media in everyday forms, such as film, adverts in written form, and exhibitions publicising the cause. Lastly, this analysis approaches transnationalism, modernism, and the scientific nature of the Estado Novo's nationalism from new and innovative angles, allowing for a “rethinking” of said nationalism.
