transfusion of blood

What if someone who has cancer and he doesnt know about, will be giving transfusion of blood to another one. Doesnt exist any danger that some cancer cell (or more cancer cells) wandering in his blood cycle will pass to the body of receiver and will initiatate an uncontroling proliferation. Or does exist any tests to test it?

the bloodbanks definitely check up against such eventualities.
not only cancer, even diseases like AIDS, etc which can be transferred by blood. when the blood group is checked, i think such other testsare also carried out.
in fact, one of the advantages of blood donation is said to be that even if u dont know whether or not u have a disease, u get to find out for free......

Does it mean that by blood tests u can find out if u have cancer? I dont think :roll:

Me neither... But i think that even if somehow a cancer cell would end up in your blood stream it would get eaten by monocytes and neutrofiles anyway... And i think they have a way to purify the blood...

if the cell is in the blood wouldn't it be metastasizing? Would that be noticiable?

Yeah thats fact. :wink:

If so, they should have a time period after which they can this blood bring to use. How long can it be? :?:

If he or she transfer his or her blood to another person, i think all transfusion of blood would be check by nurses. :wink:

I hope so.

Quote from MrMistery:

On virology teacher mentioned experiment where cancer cells from one animal (mouse) where inserted to the body of another animal (guinea pig) and they flourished there. He didnt mention if it had suppressed imunity. :roll:

How can it be? woudn't the neutrofiles recognise the foreign cell as an antigen?

That's if they're detected by our immune system by forming a complex receptor-antigen with them....after all, making a problem with macrophage, PMN (polymorph nuclear) cell and ADCC (Antibody Dependent Cell mediated Cytotoxicity) cell such as NK (Natural Killer) cell would not end all the cancer cells. The antigen from cancer cells must be brought to Lymphocyte B and T to end it....but the steps are too complicated... :lol:

Yeah but there will be only a few cancer cells in the blood...

by **victor** » Mon Nov 07, 2005 1:29 pm

Yup, little and undetected....that's what they need to make a cancer..
