The treatment of colorectal cancer is based upon location and tumor stage. The TNM-System is used for describing the spread of the tumor (stage): T=tumor (size of the tumor; how far has it spread or has it invaded surrounding tissues), N=node (are lymph nodes affected or not), M=metastasis (development of metastasis). UICC (Union of International Cancer Control) staging is based upon this classification scheme.

The grade describes how closely the tumor cells resemble normal cells, giving information about the aggressiveness of the tumor.

Here you can find more information about staging and grading: Krebsinformationsdienst des DKFZ and the Felix Burda Stiftung.

The staging will determine the optimal treatment.
