Sentinel nodes first place cancer will spread to reach lymph nodes. Can remove and do a biopsy to determine if it has spread to lymph nodes. Used commonly for breast cancers and melanomas. Radioactive dye injected near tumor site, identify where sentinel nodes are, first lymph nodes taking up dye, shows where it has spread and how far it has spread. T primary tumour and size of the tumor growth. N how far the cancer has spread to lymphnodes, determine further invasion. N1 mobile nodes involved, spread to close lymph nodes. N2 spread to distant lymph nodes. M1 clear evidence of at least one other secondary site. M2 more than one secondary site. Actual cancer cells and tissues compared to the healthy cells. Features of different cancer cells and tissues. How this is affecting the human body, how large the primary tumor is, how far it has spread to secondary sites. Interested in what stage the patient is in.
