Main outcome of study (acc. to author)

One hour of radiation treatment given every day to three tumoral human stable cell lines, produced a noticeable inhibition of the cellular growth. The same treatment given to two healthy cell lines gave a weak growth stimulation. A scanning electron microscopy study of irradiated cells (stable cancer cell lines) revealed that MMW irradiation induced profound morphological changes of the membrane. The results open a very interesting research direction which is linked to the possible use of low power MMW irradiation against tumor cells, without damaging other tissues.
