This summary table contains detailed information about research studies. While viewing summary tables offers an informative glimpse at the science behind many breast cancer guidelines and recommendations, they should be viewed with some caution. There are a number of concepts you must understand to be able to successfully read and interpret research tables. To get some background information about understanding research tables, please see How to Read a Research Table.

Introduction: Tumor size is related to both breast cancer recurrence and survival. The Surveillance, Epidemiology, and End Results (SEER) Program collects cancer-related data from a large portion of the United States. SEER data show clearly that as tumor size increases, five-year breast cancer survival decreases.
Study selection criteria: Most recent published SEER data on tumor size and breast cancer survival.
