Abstract

The detection of breast cancer in humans by evaluating antigen induced leukocyte adherence inhibition caused by tumor specific cell mediated immunity by incubating a measured amount of a patients blood leukocytes with aqueous basic extracts of human breast tumor, then determining whether the leukocyte adherence inhibition measured by the non-adherence index as compared to a control of a non-specific antigen is high, indicating the presence of breast cancer, or low, indicating the absence of breast cancer.
