National Cancer Registrars Week – April 7-11, 2025

National Cancer Registrar Week holiday is observed during the first full week of April every year by the National Cancer Registrars Association (N.C.R.A.). This year, it takes place from April 7 to 11. It promotes the work of cancer registry professionals and the remarkable role these professionals play in cancer treatment and control policies. Cancer registry professionals are fundamental to collecting and registering data and information about cancer patients. Their work provides researchers, healthcare providers, and public health officials with a detailed map of this disease throughout the U.S. and allows an improvement in cancer treatments, prevention and research.

History of National Cancer Registrars Week

The first consistent theory found in history about cancer was made in ancient Greece by physician Hippocrates. For him, cancer was caused by an accumulation of black bile. Renaissance anatomists, however, proved Hippocrates’ theory unfounded after several dissections performed on cancer victims at the time found no evidence of black bile.
From the 19 century onwards, the development of optical instruments and later improved diagnostic tools made cancer research develop rapidly. Today, with medicine increasingly based on reading and processing data, a new type of researcher has become fundamental to understanding this disease: they are cancer registrars.

National Cancer Registrar Week was first observed in 1997 by the newly formed National Cancer Registrars Association (N.C.R.A.), a non-profit organization representing over 6,500 cancer registry professionals and Certified Tumor Registrars. It was celebrated by cancer and tumor registry professionals to emphasize the vital role cancer registrars play in fighting cancer.
But the story doesn’t start there. Before it became the N.C.R.A., the organization was known as the National Tumor Registrars Association, and its origin dates back to 1974. When National Cancer Registrars Week was created to promote the work of cancer registry professionals, the N.C.R.A. already had the foundation of the previous organization of research and established standards of education for tumor registrars.

Currently, National Cancer Registrar Week aims to promote cancer registrar recognition and correctly recognize how the cancer data collected provides essential information to researchers, healthcare providers, and public health officials. The idea is to better monitor and advance cancer treatments and improve cancer prevention and screening programs.
