肺癌是全球癌症死亡的最主要原因，大約80％的患者是肺癌中的非小細胞肺癌(NSCLC)。 NSCLC的主要治療方法是手術、化療、放射線治療和標靶治療。然而，這些治療伴隨著副作用，讓患有肺癌的患者仍然預後不良。
許多研究人員已研究電磁場與生物相互關係，發現對癌細胞有生物學效應，並且暴露特定的頻率、暴露時間和磁場強度的電磁場，會讓癌細胞的細胞活性降低，產生抑制的現象。近年的大多提及是電磁場與細胞內鈣離子產生共振現象，影響癌細胞的生長，進而促使癌細胞走向凋亡。基於以上理由，我們嘗試用舒曼共振頻率7.83 ± 0.3 Hz結合不同電磁場的參數來探討其對肺癌細胞的影響。
我們的研究結果顯示，肺癌細胞在舒曼共振頻率7.83 ± 0.3 Hz，線圈電流為51.4 mA，且切換暴露6小時持續兩天之後，發現對癌細胞有顯著的抑制現象，抑制率為88 %。此外癌細胞的存活率隨著磁場強度提高也有變化，我們推測此結果可能與鈣離子共振、電磁場的強度、細胞特異性和暴露時間的參數共同影響。

Lung cancer is the most leading cause of cancer deaths in the world, and approximately 80 % of patients are non-small-cell lung cancer (NSCLC) among lung cancers. The typical treatments in NSCLC are surgery, chemotherapy, radiotherapy and target drug therapy. However, these treatments are accompanied with side effects, patients with lung cancer still have a poor prognosis.
Many researchers have studied the relationship between electromagnetic fields and biology that have been founded biological effects on cancer cells. Exposure to specific frequencies, exposure times, and magnetic field intensity of EMF can reduce the cell viability and cause inhibition of cancer cells. In recent years, most of the theories have mentioned that EMF resonates with intracellular calcium ions, affecting the growth of cancer cells and promoting cancer cells to apoptosis. Base on above reasons, we use the Schumann resonance frequency of 7.83 ± 0.3 Hz that combined with the different parameters of EMF to explore the effect on lung cancer cells.
Our results show that lung cancer cells are significant inhibition of cancer cells after being exposed parameters of coil loop current 51.4 mA at Schumann resonance frequency of 7.83 ± 0.3 Hz and switching exposure for 6 hours in two days. The cell inhibition rate is as high as 88%. Furthermore, the cancer cell viability changes with the increasing of magnetic field intensity. We speculate that the results may be influenced by parameters of calcium ion resonance, electromagnetic field intensity, cell specificity, and exposure time.
