The purpose of this study is to classify breast types and to inquire about characteristics depending on breast types of women subjects in their twenties. We researched size items affecting breast volume and regression equations for the prediction of breast volume, and thereby, we will be able to provide some basic data, useful to the development of the brassiere depending on breast types. As a result of categorizing the types of three breast types, "type 1" was characterized by big and greatest protrusion of the breast with large breast volume and a large bust, while "type 2" was characterized by flat breasts with the least breast volume and least bust, and "type 3" was characterized by breast location apart from the center front line. Breast volume is significant in establishment of the brassiere cup depending on breast type. Five items such as, the circumference of the breast, the length of the upper breast, the depth of the breast point, the length of the shoulder point-breast point, and the length of the inferior breast were extracted through regression equations for breast volume.

The purpose of this study is to provide the fundamental data for a dummy design used I read-made clothing and underwear production I terms of a pattern of breast types based o their morphological characteristics in accordance with different pattern of breast types. The breast's side and frontal views of the breast were measured with 90 junior high school girls of age between 13 and 16 residing in the urban area of Seoul using the plan photogrammetry. 1. The correlation between the side view body measurement and the breast's side and front view were analyzed by using the canonical correlation analysis, whereby the side view body measurement is showing a 39% of the breast's side view and frontal view. 2. The breast's side and front view has been classified by cluster analysis. The results of custer analysis for the breast's side and front view would be turned out the four cluster. 1) The cluster Ⅰ, The most volumed breast's side view.(20%) 2) The cluster Ⅱ, The fastest growing breast's front view.(38%) 3) The cluster Ⅲ, the latest growing breast.(3%) 4) The cluster Ⅳ, the middle degree growing breast.(39%)

Literature indicates an increased risk of suicide among women who have had cosmetic breast implants. An explanatory model for this association has not been established. Some studies conclude that women with cosmetic breast implants demonstrate some characteristics that are associated with increased suicide risk while others support that the breast augmentation protects from suicide. A systematic review including data collection from January 1961 up to February 2014 was conducted. The results were incorporated to pre-existing suicide risk models of the general population. A modified suicide risk model was created for the female cosmetic augmentation mammaplasty candidate. A 2-3 times increased suicide risk among women that undergo cosmetic breast augmentation has been identified. Breast augmentation patients show some characteristics that are associated with increased suicide risk. The majority of women reported high postoperative satisfaction. Recent research indicates that the Autoimmune syndrome induced by adjuvants and fibromyalgia syndrome are associated with silicone implantation. A thorough surgical, medical and psycho-social (psychiatric, family, reproductive, and occupational) history should be included in the preoperative assessment of women seeking to undergo cosmetic breast augmentation. Breast augmentation surgery can stimulate a systematic stress response and increase the risk of suicide. Each risk factor of suicide has poor predictive value when considered independently and can result in prediction errors. A clinical management model has been proposed considering the overlapping risk factors of women that undergo cosmetic breast augmentation with suicide.

The purpose of this study was to analyze the breast growth variation trends and characteristics of Korean adolescent girls based on 3D body measurements. Subjects were 174 girls aged between 13 and 18. 3D body scanning data were collected and the data were measured by Geomagic Design X program. The total of 18 anthropometric measurements and 4 index items were analyzed. The main results of this study are as follows: 1) Overall, the breast growth of adolescent girls got out of children's body shapes at the age of 14 and the adult's body shapes appeared remarkably at the age of 18. Before the age of 15, the adolescent girls' breast enlarged. 2) The surface lengths of upper body, which means the breast volume, showed significant growth above B cup groups rather than under A cup groups. The demand of B cup size (32.2%) was higher than A cup size (25.9%). And 35.6% of subjects' brassiere band size was 70. 3) The thorax grew evenly in the circumference, depth and breadth. The thoracic development related to the breast volume as well as the whole upper body's development. These results reveal that it is necessary to develop adolescent girls' brassiere reflecting on adolescent girls' breast growth variation trends and characteristics by age, breast size and thoracic development.

Breast ultrasonic reading is critical as a primary screening test for the early diagnosis of breast cancer. However, breast ultrasound examinations show significant differences in diagnosis based on the difference in image quality according to the ultrasonic equipment, experience, and proficiency of the examiner. Accordingly, studies are being actively conducted to analyze the texture characteristics of normal breast tissue, positive tumors, and malignant tumors using breast ultrasonography and to use them for computer-assisted diagnosis. In this study, breast ultrasonography was conducted to select 247 ultrasound images of 71 normal breast tissues, 87 fibroadenomas among benign tumors, and 89 malignant tumors. The selected images were calculated using a statistical method with 21 feature parameters extracted using the gray level co-occurrence matrix algorithm, and classified as normal breast tissue, benign tumor, and malignancy. In addition, we proposed five feature parameters that are available for computer-aided diagnosis of breast cancer classification. The average classification rate for normal breast tissue, benign tumors, and malignant tumors, using this feature parameter, was 82.8%.

Background: The National Breast Cancer Audit Database of the Society of Breast Surgeons of Australia and New Zealand is used by surgeons to monitor treatment quality and for research. About 60% of early invasive female breast cancers in Australia are recorded. The objectives of this study are: (1) to investigate associations of socio-demographic, health-system and clinical characteristics with treatment of invasive female breast cancer by mastectomy compared with breast conserving surgery; and (2) to consider service delivery implications. Materials and Methods: Bi-variable and multivariable analyses of associations of characteristics with surgery type for cancers diagnosed in 1998-2010. Results: Of 30,299 invasive cases analysed, 11,729 (39%) were treated by mastectomy as opposed to breast conserving surgery. This proportion did not vary by diagnostic year (p>0.200). With major city residence as the reference category, the relative rate (95% confidence limits) of mastectomy was 1.03 (0.99, 1.07) for women from inner regional areas and 1.05 (1.01, 1.10) for those from more remote areas. Low annual surgeon case load (${\leq}10$) was predictive of mastectomy, with a relative rate of 1.08 (1.03, 1.14) when compared with higher case loads. Tumour size was also predictive, with a relative rate of 1.05 (1.01, 1.10) for large cancers (40+ mm) compared with smaller cancers (<30 mm). These associations were confirmed in multiple logistic regression analysis. Conclusions: Results confirm previous studies showing higher mastectomy rates for residents of more remote areas, those treated by surgeons with low case loads, and those with large cancers. Reasons require further study, including possible effects of surgeon and woman's choice and access to radiotherapy services.

The aim of this study was to detail characteristics of mammary Paget's disease (PD) representing the whole population in China. A total of 4211 female breast cancer inpatients at seven tertiary hospitals from seven representative geographical regions of China were collected randomly during 1999 to 2008. Data for demography, risk factors, diagnostic imaging test, physical examination and pathologic characters were surveyed and biomarker status was tested by immunohistochemistry. The differences of demography and risk factors between PD with breast cancer and other lesions were compared using Chi-square test or t-test, with attention to physical examination and pathological characters. The percentage of PD was 1.6% (68/4211) in all breast cancers. The mean age at diagnosis was 48.1, and 63.2% (43/68) patients were premenopausal. There is no difference in demography and risk factors between PD with breast cancer and other breast cancer (P > 0.05). The main pattern of PD in physical exam and pathologic pattern were patients presenting with a palpable mass in breast (65/68, 95.6%) and PD with underlying invasive cancer (82.4%, 56/68) respectively. The rate of multifocal disease was 7.4% (5/68). PD with invasive breast cancer showed larger tumor size, more multifocal disease, lower ER and PR expression and higher HER2 overexpression than those in other invasive breast cancer (P < 0.05). These results suggested that PD in China is a concomitant disease of breast cancer, and that PD with underlying invasive cancer has more multiple foci and more aggressive behavior compared with other breast invasive cancer. We address the urgent needs for establishing diagnostic and therapeutic guidelines for mammary PD in China.

To investigate patient, cancer and treatment characteristics in females with breast cancer from more remote areas of Australia, to better understand reasons for their poorer outcomes, bi-variable and multivariable analyses were undertaken using the National Breast Cancer Audit database of the Society of Breast Surgeons of Australia and New Zealand. Results indicated that patients from more remote areas were more likely to be of lower socio-economic status and be treated in earlier diagnostic epochs and at inner regional and remote rather than major city centres. They were also more likely to be treated by low case load surgeons, although this finding was only of marginal statistical significance in multivariable analysis (p=0.074). Patients from more remote areas were less likely than those from major cities to be treated by breast conserving surgery, as opposed to mastectomy, and less likely to have adjuvant radiotherapy when having breast conserving surgery. They had a higher rate of adjuvant chemotherapy. Further monitoring will be important to determine whether breast conserving surgery and adjuvant radiotherapy utilization increase in rural patients following the introduction of regional cancer centres recently funded to improve service access in these areas.

Background: Mammographic density determined according paranchymal patterns is a risk factor for breast cancer and its relationships with body and other breast characteristics of women is important. The purpose of the present study was to correlate breast parenchymal patterns and mammography abnormality findings with women's BMI, compressed breast thickness (CBT) and age in Tabriz city, Iran. Materials and Methods: From 1,100 mammograms interpreted by radiologists, breast parenchymal was classified into four categories from Types 1 (mostly fatty) through 4 (mostly fibroglandular tissue). Age, BMI, and CBT were recorded and their relation with risk for the development of breast abnormalities in mammograms was analyzed. Results: In women with a mean age of $45.8{\pm}8.63years$ 17.7% were in the high density group (Type 3 and 4). A comparison of four types of breast paranchymal with BMI, CBT and age showed inverse relations to breast density. Abnormal mammographic findings were 25.8% of all reported mammograms with a circular mass (12.7%) as the most common abnormality. About 21% abnormal cases were in less than 40 years. Increasing of BMI had significant relation with breast abnormality but in CBT was not observed. Conclusions: Measurement of women's body characteristics is useful for assistance in mammography diagnosis as well as selection of imaging instrument by high sensitivity for following patient in future. The effects of age, CBT and BMI groups on the breast paranchymal were significant.

Breast cancer is the most common cancer in Jamaican women. This study assessed the clinicopathologic features of cases in a hospital-based specialist clinic in Kingston, Jamaica. A retrospective chart review was performed for the 2-year study period and relevant clinical and surgico-pathologic data were recorded and analyzed. Median age of the 121 breast cancer patients was 52 years (range 22-84, IQR 20) and there was 1 case of male breast cancer. Most patients (65%) were referred from the surgical service after definitive breast cancer surgery, 20% were referred for pre-operative systemic therapy, and 15% had a diagnosis of metastatic disease. The surgico-pathologic group comprised 78 women who were referred for adjuvant therapy. The majority had presented with a palpable breast lump (91%), with median tumour size 3.5cm (range 0.4-13, IQR 4). Most tumours were node positive (56%). Approximately one-third of patients had stage III disease (33%). Most women presented with large palpable tumours and had lymph node involvement confirmed on surgicopathological evaluation, indicative of limited early breast cancer detection. A national screening mammography programme is recommended for detection of earlier lesions. Pre-operative systemic therapy should be considered as an option for eligible patients.
