The American Joint Committee on Cancer (AJCC) is a nonprofit organization founded in 1932 that focuses on cancer research and education. Its primary mission is to improve cancer care by providing a standardized system for cancer staging, which helps healthcare professionals determine the extent of cancer in patients. This staging system is crucial for treatment planning and predicting patient outcomes. The AJCC is known for its AJCC Cancer Staging Manual, which is regularly updated to reflect the latest scientific findings. The committee collaborates with various organizations, including the American Cancer Society, to promote awareness and improve cancer treatment across the United States and globally.
