What i meant is that the immune system should have no trouble dealing with 1 or 2 cancer cells

You're absolutely right. It's estimated that, by the time you turn 18, your immune system has efficiently dealt with 30 potential cancer instances. There is beauty in control of our replicating cells, friends.

In blood plasma there is a lot of immune 'toolbox', one of them is cytokines released by host cells or tumor cells. By analyzing plasma, we can detect the presence of abnormal cells that potentially become tumor cells whether benign or malignant.

Paramedicals or people in blood labs know what they should do due to blood transfusion so don't worry.

They dont allow that, every person before they donate goes through a screening session, where the persons history is revealed, and they approach every aspect of health with a qualified nurse. Then, after that is all clear, they do a blood test, and send that for screening. If the blood is compatibile, and the testing is fine, they then consider the donor. Before somebody can donate bone marrow, the same screening applies.

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?


i dont think that cancer can b transfered in any such way.. and v have our immune system too..

No it can not. Red blood cells are the cells transfused. Cancer is defined as "uncontrolled cell division." Since RBC's do not divide in the first place, and they cannot even if they wanted to (no DNA), cancer cannot be communicated in this way.

I think the question was about a cancer cell breaking from it's tissue and accidentally ending up in the blood stream

Remember that blood plasma consists of a lot of immune system tools like antibodies, complements, and cytokines. Also, in blood stream we have leucocytes that will attack tumor/cancer cells. One more, blood flows to "transit places" called spleen and lymph nodes that will detect and clean blood, even another body fluids i.e. lymphs, before continuing its flowing.
