Abstract

In quantitative measurements of the attenuation of ultrasound in 18 samples of variously normal, benign, and malignant breast tissue, we found significantly different ranges of attenuation. As observed in previous in vivo studies, with the exception of medullary carcinoma, malignant tissue produces the most attentuation of ultrasound in the frequency range of 1.5 to 3.0 MHz we employed. The apparatus, measurement method, results, and the possible causes of the differences in attenuation are presented.

Cytogenetic and molecular studies have suggested that the 3p14.2 chromosome subband contains tumor suppressor genes involved in the pathogenesis of many types of human cancers. Recently, the FHIT (fragile histidine triad) gene was identified in this part of chromosome 3 as a candidate suppressor gen

## Abstract The assessment of DNA had demonstrated altered methylation in malignant compared to benign breast tissue. The purpose of our study was to (__i__) confirm the predictive ability of methylation assessment in breast tissue, and (__ii__) use the genes found to be cancer predictive in tissue
