There isn't a visible imune response to cancer, so it might not even attack them. I'm not sure, but if I had to take a guess I'd say it was because cancer cells are taken as normal cells, according to the imune system. Anyway, I remind you, this isn't based on anything, just my general knowledge.
Edit: Besides this, there might be also more possible explanations: The imune response is centered at lymph vessels and normally, to kill a virus, leukocytes take the virus to the vessels. Since cancer cells can't change place, they can't be taken there. More, according to my father, they are too many to be killed easily.
White blood cells do not kill cancer. If it were that simple, nobody would have it.
Cancer kills an organism by destroying the red blood cells.
White blood cells that directly destroy virus-infected and cancerous cells are called?
-White blood cells White blood cells are like policemen in bloodstream. They are constantly on patrol for infected cells. (Yes; they usually eat them -aka kill them.)
White Blood Cells make a chemical called Interferon, which white blood cells use to kill bacteria and germs.
The radiation kills bone marrow, where both red and white blood cells are made. The white blood cells produce most of the immune system, with fewer white blood cells the immune system weakens.
white blood cells
every living thing has white blood cells they kill viruses
white blood cells in the blood
No
Chemotherapy goes through the body and destroys cells. Cancer cells are the weakest so they die first. The goal of chemo is to kill as many cancer cells as possible without killing the patient i.e. healthy cells. But unfortunately healthy cells die too. White blood cells are the first to go. Which is why they take your blood every week, to monitor your counts. There is a shot which can increase the white blood cell production rapidly so you can resume therapy without much break.
Bacteria can attack and kill cells. White blood cells can kill bacteria.
You Must mean White blood cells. White blood cells kill bacteria by first engulfing them, this process i believe is called phagocytocis. They literally eat the bacteria and digest it.
