A method of using a diffusion-based, continuous-monitoring system to analyze for a disease or condition includes creating a diffusion channel in an area of skin. The diffusion channel is maintained for a desired duration. The level of the disease marker(s) is continuously monitored for the desired duration via a diffusion-based, continuous-monitoring device. The levels of the at least one disease marker at the area of skin are analyzed to determine if the disease or condition associated with the at least one disease marker is present.
