A

Via seeding of body cavities
Common examples are pleural cavities

18
Q

Perineural

A

Via nerves

19
Q

Tumor spreads

A

T= tumour size or local invasion
N=nodes:number of lymph nodes involved
M=metastases presence of distant metastases

20
Q

Grade and stage

A

Grade is how differentiated the tumour is stage is how far the tumour has differentiated
