Measuring nitric oxide concentration in tissue

摘要

The present invention involves the measurement of nitric oxide in interstitial fluid extracted by a thin needle from a body tissue, and particularly a human breast. The diffuse nature of nitric oxide means that the sample of body fluid does not need to be taken directly from the lesion to indicate that cancerous cells are present in the vicinity. Therefore, the presence of nitric oxide in the extracted body fluid is a direct indicator of the presence of a cancerous lesion in the vicinity.
