Abstract
Abstract A METHOD IS PROVIDED FOR DETERMINING WHETHER CANCER IS PRESENT IN A TISSUE. THIS METHOD MAKES USE OF THE BIOLUMINESCENT REACTION BETWEEN ATP AND FIREFLY LANTERN EXTRACT AND MEASURING THE AMOUNT OF LIGHT WHICH IS EMITTED. A COMPARISON IS MADE BETWEEN CELLS TAKEN FROM THE SUBJECT WHICH ARE KNOWN TO BE NONCANCEROUS AND THE CELLS WHICH ARE THOUGH TO BE CANCEROUS. THE PRESENCE OF CANCER IS INDICATED BY A SIGNIFICANTLY LESSER AMOUNT OF LIGHT BEING EMITTED BY THE SAMPLE WHICH IS SUSPECTED TO CONTAIN CANCER.
