Effect of Medium Irradiated with Atmospheric Pressure Plasma on Cultured Colorectal Cancer Cells

Several studies have reported the use of atmospheric pressure plasma irradiation for medical applications. Atmospheric pressure plasmas produced under atmospheric pressure, so they contain many neutral molecules, ions, and radicals. Radicals are highly reactive and have the property of damaging cancer cells. We have previously studied the effects of plasma-treated water irradiated with atmospheric pressure plasma on the colon cancer model rats. In this study, we investigated the mechanism of suppression of cancer progression by irradiating the culture medium of colon cancer cells with atmospheric pressure plasma.
