MEASURING NITRIC OXIDE CONCENTRATION IN TISSUE

摘要

The present invention involves the measurement of nitric oxide in interstiti al fluid extracted by a thin needle from a body tissue, and particularly a huma n breast. The diffuse nature of nitric oxide means that the sample of body flu id does not need to be taken directly from the lesion to indicate that cancerou s cells are present in the vicinity. Therefore, the presence of nitric oxide i n the extracted body fluid is a direct indicator of the presence of a cancerou s lesion in the vicinity.
