UICC/AJCC staging

In the world of cancer, there's a classification, Called TNM, a global sensation. It tells us how tumors spread and grow, With codes and stages, it helps us know. T is for tumor, the primary site, It tells us its size and if it's taking flight. Has it invaded nearby tissue, we ask? T1, T2, or T3, we unmask. N is for lymph nodes, nearby and close, Are they involved? That's what we suppose. N0 means they're clear, N1 means they're there, The stage of the cancer, we begin to share. M is for metastasis, a word quite grand, Has the cancer spread to a distant land? M0 means it's contained, M1 means it's spread, With this information, we move ahead. TNM, a system so widely used, By doctors and researchers, it's not confused. It helps us understand the cancer's progression, And guides us in treating this difficult lesson. Random page: LR-5182
