PURPOSE: A metastasis inhibiting method of a cancer cell using a magnet is provided to offset the additional damages of malignant tumors through a magnetic field by using the fact that a static magnetic field suppresses the metastasis of a cancer cell.CONSTITUTION: A metastasis inhibiting method of a cancer cell using a magnet controls or suppresses the metastasis of a cancer cell by using a magnet on purpose. A metastasis inhibiting method of a cancer cell comprises the following steps: Cancer cells and the semi-permeable film are put on a 24-well plate in order. The number of cells, which oozing out, is measured after the cells is incubated at the temperature of 37°C for 6 hours. The static magnetic field(magnet) process group and the cell type should be the same in the control group and the experimental group. The cells which pass through the semi-permeable single film, of which the diameter is 8 Mm, is counted.COPYRIGHT KIPO 2013자석은 우리 생활의 전자제품에 많이 쓰이는 물체이다. 이를 이용하여 암세포의 이동성을 유의하게 억제할 수 있다는 것을 실험을 통해 확인하였다. 악성 종양은 매우 전이할 가능성이 높은 종양이다. 이러한 종양 근처에 충분한 세기 (본 실험에서는 0.2T 이상) 의 자석을 놓으면 추후 악성종양에 의한 피해를 줄일 수 있을 것이라고 사료된다.
