Mammography is the most effective method for the early diagnosis of breast cancer diseases. As mammographic images contain low signal to noise ratio and low contrast, it becomes too difficult for radiologists to analyze mammogram. To deal with the above stated problems, it is very important to enhance the mammographic images using image processing methods. This paper introduces a new image enha...
BACKGROUND We have examined the relationships between the measured properties of breast tissue and mammographic density and other risk factors for breast cancer, using breast tissue obtained at forensic autopsy and not selected for the presence of abnormalities. METHODS We used randomly selected tissue blocks taken from breast tissue slices obtained by s.c. mastectomy at the time of forensic ...
BACKGROUND High-density lipoprotein cholesterol (HDL-C) is reported to be associated with breast cancer risk. To better understand this association, we examined the relationship between HDL-C and mammographic density, a putative intermediate risk factor for breast cancer. METHODS The study subjects were 711 Korean women from the Healthy Twin study. Lipid parameters were assayed enzymatically ...
BACKGROUND Mammographic density is a strong heritable trait, but data on its genetic component are limited to area-based and qualitative measures. We studied the heritability of volumetric mammographic density ascertained by a fully-automated method and the association with breast cancer susceptibility loci. METHODS Heritability of volumetric mammographic density was estimated with a variance...
