The reduction of NK Cell Count and effectiveness in NK Activity is associated with several types of cancer, according to the table.

Determination of NK Cells in the blood helps us to know whether there is a risk of cancer. In addition, it can help us to decide whether the patient is strong enough to be treated with radiation. Patient with NK cell deficiency or low NK cell count has high risk in cancer development. Because NK cell is the first step to detect and kill cancer cells before cancer cells continuing to multiply and ultimately uncontrollable. Currently, NK Cell Count and NK Activity can be checked to assess the ability of individual in destroying cancer cells.
