We were comparing the adherence ability of T lymphocytes gained from blood of patients with head and neck carcinoma before launching the treatment before and after their exposure to magnetic field of power frequency of 50 Hz with induction of 10 mT, 1 mT, 0.5 mT and 0.1 mT. The gained results have proved that magnetic field has a statistically significantly increases the ability of adherence in unhealthy T lymphocytes in all applied inductions, including a very low-level induction of 0.1mT. In case of 0.5mT induction, namely statistical level of importance worth 0.001 is in question. There is no statistically significant difference among the average values measured in all groups without the influence of magnetic field. For values received by measuring in magnetic field a statistically significant difference has been proved among the NAI values in inductions of 0.1mT and 10 mT (level of importance of 0.05), and inductions of 0.5mT and 10mT (level of importance of 0.001).

If we consider the lymphocytes adherence ability a sign of cell-mediated immunity, it is clear that magnetic field of power frequency has an influence on cell-mediated immunity in patients with head and neck carcinoma, namely statistically significantly in all tested inductions (including a minimum induction of 0.1mT).
