What are the stages of cancer based on?
Location of tumor, Size, Lymph node involvement, cell type and tumor grade (how close to normal cells) Metastasis
T
stands for Primary Tumor
-Tx: Cannot be evaluated
-T0: No regional lymph node involvement
-Tis - Carcinoma in situ (eary cancer that has not spread to neighboring tissue)
T1, T2, T3, and T4 - size and extent of tumor
N
Regional lymph nodes
Nx: Redgional lymph nodes cannot be evaluated
N0: No regional lymph nade involvement (no cancer found in the Lymph nodes)
N1 N2, N3
M
Distant Metastasis
Mx: Distant metastasis cannot be eval.
M0: no distant metastasis (no spreading to body)
M1: Distant metastasis (cancer has spread)
