Abstract
We have studied the effect of an alternating magnetic field on the growth rate of the two-dimensional C6 rat glioma tumor. Tumors growing on a plate surface were subjected to a 10-mT magnetic field at frequencies from 10 to 50 Hz. The rate of tumor growth at each frequency studied was measured and compared with a control group growing in the absence of the field. Tumor growth rate at each frequency was increased compared with a control group. The highest growth rate was observed with a magnetic field at a frequency of 20 Hz.
