If cancer cells are foreign and harmful to our body how come our immune system doesn't fight it?
Yes our immune system does fight it. These are the NK cells. NK cells naturally present Inhibitory R and NK R. Target cells do not present MHC but present the ligand for NKR. So although lignad on NK binds to NKR, there is no MHC to interact with inhibitory R. So NK cells do not receive inhibitory signal and attacks the cell (e.g. cancerous cell). But at times there may be cancer cells undetected, which is why our immune system can't 'sense' it.
