Breast cancer is growing rapidly year by year and has the highest incidence since 2001. As a result, the interest in mammography for early detection of breast cancer is increasing. However, mammography is accompanied by radiation exposure and therefore it is necessary to reduce exposure dose through appropriate test conditions. The significance of this study is that breast dose studies, which were limited to ordinary women, were applied to breast implant patient. Using MCNP simulation, the phantom with prosthesis inserted was developed to compare dose by tube voltage by pressure thickness. In addition phantom without prostheses has higher dose than phantom with prostheses. If these results were used as basic data, it would be possible to recommend test condition guideline only for breast implant patients.

The role of ultrasound-guided interventions in the diagnosis and treatment of breast lesions is gaining importance and prevalence, particularly as the instances of non-palpable breast lesion detection, breast-conserving surgery, and neoadjuvant chemotherapy are increasing. This review attempts to summarize the types and techniques of breast ultrasound-guided interventional procedures, such as biopsy, tissue marker insertion, and preoperative localization, and their indications. Furthermore, we highlight the pro and cons of the most commonly used procedures with the intention of promoting their use in clinical practice.

Ectopic breast tissue, which results from incomplete regression of the mammary line during embryogenesis, is observed in 0.2%-6% of the population. Carcinoma development in ectopic breast tissue, especially in the abdominal or chest wall, is rare. Here we present the unusual case of a 38-year-old woman with invasive ductal carcinoma in the ectopic breast tissue on the left side of the chest wall and concurrent fibroadenoma in the ectopic breast tissue on the right side. We also describe the US and MR findings of these masses.

대표적인 서구암으로 알려진 유방암이 최근 들어 무서운 속도로 증가하고 있다. '2009년 보건복지부 국가암등록' 통계에 따르면 유방암은 우리나라 여성암 중 갑상선 암 다음으로 가장 많이 거리는 암인 것으로 밝혀졌다.

Breast cancer is the sccond most female cancer patient in the entire female cancer patient, and has emerged as the highest contributor to female cancer deaths. If breast cancer id detected early, the cure rate is 92 percent. However, if early detection fails, breast cancer has a very high rate of metastasis. The transition from cancer to cancer has become more successful as cancer progresses. Early diagnosis of cancer is an important factor in improving quality of life. Examples of breast cancer include Mammograph, ultrasound, and Momotome. Mommography is not only painful for the examiner, but also for easy access to breast cancer exam inations. In this paper, breast cancer diagnosis data mammograph data was used. In addition, the Neural Network were classified for early diagnosis of breast cancer early using NEWFM. After learning of data using NEWFM, the accuracy of the breast cancer data classification was 84.4391%.

We carried out studies on development and characteristic of ultrasound brast training biopsy phantom. the major finding were of follow ; (1) C type TMM was shown good homogeneity, brightness and attenuation as like human soft tissue. (2) $TiO_2$ 4.10%w/v TMM was shown good homogeneous echo texture and propagated speed as like the human Tissue. (3) $TiO_2$ type TMM was appeared lower brightness and higher penetration rate than C type TMM. Therefor, Breast TM phantom and target material TMM will be useful $TiO_2$ 4.10 %w/v TMM and C 2.09 %w/v TMM.

Authers retrospectively analyzed ultrasonographic findings of 12 cases of breast carcinomas which were proven pathologocally at Yeungnam University Hospital from March 1992 to August 1992. Classically, breast carcinomas were described as irregular and lobulated hypoechoic solid masses with inhomogenous internal echoes and frequent attenuation of the sound beam. And other additional ultrasonographic findings were echogenic rim, disruptions of superficial layer, microcalcification, skin thickening and so on. In our studies, not all of these findings of breast carcinomas were found in each case, but most of these findings were noted. However, several studies have demonstrated considerable overlap in the ultrasonographic appearance of benign lesions and carcinoma. Thus, accurate sonographic determination of the type of solid mass is not possible with current ultrasonographic imaging techniques and criteria. For more accurate diganosis of breast lesions, sonographic and other imaging techniqes are interpreted together.

Radiation exposure exposed during mammography, which is performed for early examination of breast cancer, has also been suggested as a cause of carcinogenesis in the past, and scattered rays generated during examination may cause unnecessary radiation exposure to surrounding organs. In this study, the Monte Carlo simulation was used to evaluate the human organ doses exposed during conventional mammography, and to estimate the dose reduction effect for each organ when using 3D printing materials for radiation protection by scattered rays. As a result of organ dose evaluation, the breast on the opposite side of the examination was about 22.0% of the breast on the test side and about 58.6% on the eye, which was highly influenced by the scattering-ray. When using the 3D printing shield to protect it, the breast on the opposite side of the test showed an effective dose reduction effect at a thickness of 1 mm.

Objectives : This study was aimed to grasp the stages of change in breast cancer screening of the nurses and general women who were over 20 and under 50 and specify the factors which affected the stages of change in breast cancer screening, based on Precaution Adoption Process Model. Methods : This study was conducted for 158 people who consisted of the nurses and general women who were over 20 and under 50. Results : As a result of examining the factors of cues to action and the belief in cancer screening according to the stages of change in the breast cancer screening of the nurses and general women, there was not a statistically significant difference and the perceived barriers showed a statistically significant difference in the stage of behavioral decision, the fifth stage. Conclusion : It is necessary to approach the individuals with the recommendation of cancer screening through the people around them and differentiated strategies considering the stages of change in cancer screening in order to induce the behavioral change in breast cancer screening, and develop and apply the strategies to enhance the severity perceived on the breast cancer.
