The AACR Special Conference in Cancer Research: Tumor-Body Interaction: Micro- and Macro-Environmental Determinants of Tumorigenesis will take place on November 3–6, 2027, at Hilton San Francisco Union Square in San Francisco, California, United States. The conference is organized by the American Association for Cancer Research (AACR) in association with its Tumor Microenvironment Working Group.

The four-day meeting will bring together cancer researchers, scientists, and oncology professionals to examine how interactions between tumors, surrounding tissues, and systemic biological processes contribute to cancer development and progression.

The conference will provide a platform for scientific exchange and multidisciplinary collaboration in tumor biology, with a particular emphasis on understanding cancer within the broader context of the tumor microenvironment and the host organism.
