1. A device for detecting chemicals from skin tissue, the device comprises:
at least a first detector and at least a second detector, wherein the first detector and the second detector are identical types of detectors, and wherein said second detector is a reference detector;
an attachment portion including at least said first detector and at least said second detector separated by a defined distance, said attachment portion is configured to be attached on said skin tissue for detection of said chemicals; and
wherein said first detector and said second detector are in fluid communication with said skin tissue and comprising a material configured to provide a measurable change in at least one of an electrical, a visual, and an optical property based on differences between the first detector and the second detector by an emanating metabolite from changes in dermis or epidermis due to a tumor.
