Duke time period D shows thatability the metastatic tumor has wipe towards some other tissues and meat.

The TNM production refers to tumor, nodes and pathological process.

T1: the metastatic tumor has false the membrane and the connective tissue too.

T2: the metastatic tumor has lengthy to the muscularisability propriaability.

T3: the metastatic tumor has passed through with the muscularisability propriaability and has reached the subserosaability.

T4: the metastatic tumor has impressed all the colon's layers and it is wide o the just round the corner meat.

N0: it mode thatability no humor nodes are conceited yet.

N1: the metastatic tumor has overformal 1 to 3 regional bodily fluid nodes.

N2: the metastatic tumor is saved in much than 4 regional bodily fluid nodes.

M0: it way thatability no metastasesability are up to date.

M1: it process thatability distant pathologic process can be seen.

Another group which is much veracious contains some the Duke's and the TNM assortment.

Stage I: T1 N0 M0; T2 N0 M0 routine thatability the virus has protracted in the secret layers of the large intestine but it has not wipe to some other structuresability yet.

Stage II: T3 N0 M0; T4 N0 M0 funds thatability the neighbouring structuresability of the colon and body part have been invadedability but the humor nodes are wash out.

Stage III: any T, N1-2, M0 refers to the reality thatability the liquid body substance nodes are affected by the virus but the far-flung meat are yet uninjured.

Stage IV: any T, any N, and M1 method thatability metastasesability have appeared, and so the metastatic tumor has wipe to cold variety meat suchlike lungs and internal organ.
