Explain the grading for cancer T grading in an example o the bowel
T1- bowel tissue only
T2- Grown into the muscular layer of bowel
T3- Has grown through muscle into the outer tissues
T4- Has grown to surrounding organs such as liver
Explain the grading for cancer N grading
N0- No lymph node involvment
N1- 1 to 3 lymph nodes surrounding the tissue contain cancer
N2- 4 or more cancer cells grown more than 3cm away from the tumour and are connected to blood supply vessels around the body
Explain the grading for matesis
M0- Has not spread to other organs
M1- tumours have spread to other organs in body
