BACKGROUND The role of vitamin D in breast cancer etiology is unclear. There is some, but inconsistent, evidence that vitamin D is associated with both breast cancer risk and mammographic density (MD). We evaluated the associations of MD with month the mammogram was taken, and with vitamin D intake, in a population of women from Norway--a country with limited sunlight exposure for a large part ...
OBJECTIVE This retrospective observational study was designed to answer the following question: Is mammography clinically effective in the evaluation of women </=35 years old with breast symptoms or findings. STUDY DESIGN A retrospective review was undertaken of 1908 consecutive initial mammogram reports of symptomatic women </=35 years old who came to a referral breast clinic. The clinic rec...
Sun, Yajie. Ph.D., Purdue University, August, 2004. Normal Mammogram Analysis. Major Professor: Edward J. Delp. Breast cancer is the leading cause of cancer death among women. Screening mammography is the only method currently available for the reliable detection of early and potentially curable breast cancer. Research indicates that the mortality rate could decrease by 30% if women age 50 and ...
Breast cancer is one of the most common types of cancer in women. Screening mammography is a low‑dose X‑ray examination of breasts, which is conducted to detect breast cancer at early stages when the cancerous tumor is too small to be felt as a lump. Screening mammography is conducted for women with no symptoms of breast cancer, for early detection of cancer when the cancer is most treatable an...
The increasing threat of breast cancer in developing countries may not only be handled by the existing medical setup as well as insufficient number of medical workforces. To handle the increasing volume of data produced by diagnostic imaging that can be efficiently managed by computer aided detection/diagnosis (CAD) to assist medical practitioners in image interpretation to detect structural ab...
Breast cancer is one of the leading causes of death among the women. Mammogram analysis is the most effective method that helps in the early detection of breast cancer. Microcalcification, masses, and architectural detection in the mammogram plays an important role in the later stages of diagnosis. In this paper we propose an effective method for the detection and classification of clustered mi...
Early detection of breast cancer increases the survival rate and increases the treatment options. In this paper, we present different preprocessing methods for mammogram images. The main goal of the preprocessing is to improve the mammogram image quality and make it ready for the segmentation and feature extraction. Different types of filtering techniques are available for preprocessing. Filter...
