how will metastasis occur
invade basement membrane
moves into extracellular matrix/connective tissue
invades blood vessels and lymph
what happens after tumoire reaches the blood
it arrests in a distant organ

what dose anti-VEGF do

smoking
obesity
alcohol excess
how dose cancer hide from our immue system
cangers have a ligand (PDL-1) that bind to the T lymphocytes and supress the cell

programmed death ligand 1

a ion or molecule that binds to a central larger molecule
what are the preventative therapeutic cancer options
environment/behaviour change

genetics
medicine
what are the therapeutic treatment cancer options
surgery
systematic therapy
radiotherapy
immunotherapy
what dose surgery need to ‘cure’ a cancer
anatomical clearance so the surrounding area can be cut out
what dose radiotherapy need to ‘cure’ a cancer
it needs anatomical coverage
why is cell turnover important
you need to due treatment in cycles
what are some immunotherapy’s
monoclonal antibodies
‘innate’ immune system
programmed cell death
pathway
CAR T-cell therapy
PD-1 and PDL-1 ANTAGONIS
in use atm
what is CT imaging used for in relation ship to cancer
diagnosis
staging - assecs local spread
