Newborn mice were treated with a single dose of the chemical carcinogen DMBA (35 µg, subcutaneously injection) to initiate tumor development. Two weeks later MF-exposure (50 Hz, 1 mT, 3 h/day, 6 days/week, for 16 weeks) was started. Animals were sacrificed for examination at an age of 32 weeks. A DMBA treated but sham exposed group served as control.

The incidences of lymphoma and leukemia did not differ between MF-exposed and DMBA treated mice and sham-exposed mice also treated with DMBA. However, the metastatic infiltration by lymphoma cells into the liver was significantly increased (50%) in the MF/DMBA group.
