Conventional cancer therapies are surgery, radio-therapy, and chemo-therapy. We propose plasma-therapy as the fourth cancer therapy. Plasma cancer therapy involves direct plasma treatment of cancers including melanomas, head and neck cancer, pancreatic cancer and liver metastasis, and indirect plasma treatment of cancers by using plasma irradiated solutions such as plasma-activated medium (PAM). We have been recently studying plasma cancer therapy using target cancers such as ovarian cancers, brain tumors, gastric cancers and skin cancers. We have developed a plasma source with ultrahigh electron density, which we have applied to these cancer cells. In addition, we found that plasma-irradiated medium itself can kill these cancer cells. This medium was termed plasma-activated medium (PAM). In vitro and in vivo studies h...
