A simple Ames test study I found after doing quick googling: https://journals.lww.com/eurjcancerprev/Abstract/2005/04000/.... No real mutagenic effect. Granted this does not exclude the ability for it to be carcinogenic in another manner, but I would doubt such a result.
Edit: some additional thoughts. There is a controversial treatment using EMF to treat glial blastomas (https://en.wikipedia.org/wiki/Alternating_electric_field_the...), the proposed mechanism is that it interrupts mitosis. This method is unlike the one put forward by Dr. Moskowitz which relies on an increase in necrosis/apoptosis.
