Abstract
A diagnostic process is disclosed for detecting very early or developed stages of malignancy of tissue beneath a predetermined portion of the skin of a human patient. A sample of body secretion is obtained from the outer surface of the skin and is tested for presence of markedly decreased free, naturally occurring amino acids. The test has approximately the same order of sensitivity as a standard ninhydrin test. The diagnostic process of the invention is particularly adapted for mass screening of human females for early stages of breast cancer.
Claims29
A process for determining the presence of a developed or incipient malignant tumor beneath a predetermined portion of the skin of a human being, said malignant tumor being located in a tissue substantially contiguous with the tissue underlying the predetermined portion of the skin, the process comprising the steps of:
- collecting a sample of secretion from an outer surface of the predetermined portion of the skin;
- testing at least an aliquot portion of the sample for the presence of free amino acids;
- and
- determining whether a malignant tumor is present based upon the quantity of said amino acids detected by said testing.
A process for diagnosing the presence of incipient or developed malignancy below a predetermined portion of the skin of a human being in a tissue which is substantially contiguous with tissue underlying the predetermined skin portion, the process comprising the steps of:
- collecting a sample of secretion from the outer surface of the predetermined skin portion;
- obtaining a solution of substantially known volume from said sample;
- using an aliquot of a solution derived from the sample in a chemical test for free naturally occurring amino acids, said chemical test being of approximately the same sensitivity as a substantially standard ninhydran test;
- and
- determining whether an incipient or developed malignancy is present based upon the quantity of said amino acids detected in said test.
A process for diagnosing a developed or incipient cancerous breast tissue in a breast of a human female, said incipient cancerous tissue being identified as a high risk for cancer, the process comprising the steps of:
- collecting a sample of secretion from the outer surface of the skin of the breast;
- obtaining a solution of substantially known volume from said sample;
- and
- testing an aliquot of said solution for the presence of free naturally occurring amino acids.
A process for determining the presence of a developed or incipient malignant tumor beneath a predetermined portion of the skin, said malignant tumor being located in a tissue substantially contiguous with the tissue underlying the predetermined portion of the skin comprising the steps of
- collecting a sample of secretion from an outer surface of the predetermined portion of the skin;
- testing at least an aliquot portion of the sample for the presence of ninhydrin-reactive substance;
- and
- determining whether a developed or incipient malignant tumor is present based upon the quantity of said ninhydrin-reactive substances detected by said testing.
