Which of the following statements about the history of US cancer registration is true?

The history of cancer registration in the United States is rooted in the 1920s, which marks the beginning of organized efforts to collect cancer data systematically. The first state cancer registry was established in New York in 1926, followed by the establishment of various other registries in different states throughout the 1930s. This early initiative aimed to better understand the incidence of cancer across the population and to identify trends that could inform public health strategies.

The establishment of cancer registries was driven by the need for reliable cancer statistics to help in research, treatment planning, and the development of prevention strategies. As public health awareness grew, so did the importance of comprehensive data collection. Thus, stating that cancer registration began in the 1920s is accurate and reflects the foundational efforts that shaped the future of cancer surveillance in the United States.
