TNM Cancer Staging is developed for International Atomic Energy Agency (IAEA) in collaboration with Tata Memorial Centre (TMC) and Department of Atomic Energy (DAE). TNM Cancer Staging is a system developed and updated by American Joint Committee on Cancer (AJCC) and the Union for International Cancer Control (UICC) and published as AJCC TNM staging manual to classify cancers based on the extent of its spread, on a globally recognized scale. The TNM staging system is based on the extent of the tumour (T), the extent of the lymph node spread (N) and presence of distance spread – metastasis (M). TNM Cancer Staging App will prove very helpful to the doctors around the world in assigning cancer staging to their patients. The app hosts a list of unique features like Prospective, Interactive and Universal Search across the in-app indexes.
