Which type of lymphocyte attacks cancer cells that appear in normal tissue?
Nk (natural killer) cells.
Cancer cells and virus-infected body cells can be killed before activation of adaptive immunity by?
Cancer cells and virus infected body cells can be killed before activation of adaptive immunity by natural killer cells. These may be noted as NK cells in literature.
Which blood cells in the lymph nodes destroy cellular trash?
Cytotoxic T cells and NK cells (natural killers)
What do lymphocytes contain?
Lymphocyte contains natural killer cells (NK cells) because of the initial notion that they do not require prior activation in order to kill cells.
What is a NK cell?
Natural Killer cells are lymphocytes (white blood cells specialised in immunity) that are cytotoxic, meaning that they produce toxins that affect other cells.
What Type of T cell that directly kills virus infected body cells and some tumor cells?

If you have cancer would you have an elevated wbc and what is the reason for this?
Yes, you would have a higher than normal WBC count. The common increase would be in in what are called Natural Killer (NK) lymphocytes. There are 3 functional classes of lymphocytes: 1. T cells (cell-mediated immunity) attack foreign cells directly 2. B cells (humoral immunity) differentiate into plasma cells which synthesize antibodies 3. Natural killer (NK) cells detect and destroy abnormal tissue cells such as cancers You could say that the NK's are trying their best for the body by killing as many abnormal (cancer) cells as possible.
