A method and system of adaptive cold atmospheric based treatment for diseased tissues, such as an area with cancerous cells, is disclosed. A plasma device generates a cold atmospheric plasma jet directed at the area having cancerous cells. A sensor is operable to sense the viability of the cancerous cells in the area. A controller is coupled to the plasma device and sensor. The controller is operative to control an initial plasma jet generated by the plasma device. The controller receives a sensor signal from the sensor to determine cell viability of the selected cells from the initial plasma jet. The controller adjusts the plasma jet based on the viability of the cancerous cells.
