Will CANCER compress immunity and cause false negative test?

Resolved Question:

sorry i think god wanted me to ask one last question i was just reading yr replies and saw u didnt indicate ct without contrast but only ct . did u mean ct without contrast . just to concluse  what u said  if a tumour compresses immunity  , in that case the tumour will be big enough and create symtoms which u indicated and will be easily picked up by ct scan without ct scan.  and if the tumours are minute and cant be picked by ct scan withoiut contrast  then they cannot compress immunity being so minute  and so antibodies will be there and it will not create  false negative test.   for anxiety sake just formulating ur reply so as not to  disturb u again thanks  waiting sir

Thank you for your query at
For a tumor cell ( however minute it is ) CT with/ without contrast, in either cases the tumor will be picked up.
For minute tumors, it can in no way suppress immunity, so antibodies will be seen and there will be no false negative test.
Hope this was helpful,

Patient replied :

sorry sir didnt understand first sentence of yours clearly. i had asked if a tumour has supressed the immune system will it be big enough or create sysmtoms as u mentioned picked by ct scan without contrast . second part i understood clearly sir sorry and really hope will not disturb u again

To avoid confusion, I will keep it short.
Yes it will be picked up by CT without contrast. And if it impairs immunity in any way, it has to be big enough.
