The most common cause of a palpable mass or asymmetry in male breast is gynecomastia; however, male breast cancer should not be overlooked as a cause, even though it is rare. It is important to know the anatomy and frequency of diseases that affect the male breast, and the differences compared to females, to make an accurate diagnosis and reduce unnecessary examinations and surgical procedures. This review aims to summarize the algorithm of breast exam in symptomatic men, gynecomastia, and breast cancer.

This study analyzed the factors that influence the development of gynecomastia by comparing blood test results and lifestyle between patients diagnosed with gynecomastia and normal control group. Independent sample t-test and chi-square tests were conducted to examine the mean differences among risk factors, and logistic regression analysis was used to calculate the relative risk ratio of various predictors influencing the development of gynecomastia. Age, HGB, HCT, TC, glucose, ALT, alcohol consumption, hair loss medication and medication for benign prostatic hyperplasia were identified as significant variables. Notably, the use of hair loss medication showed the highest univariate odds ratio of 15.79, while HGB decreased by a factor of 0.37. These results suggest that these could play a significant role in the onset of gynecomastia and could serve as foundational data for future diagnosis and management of the condition.

이 연구의 목적은 중년여성들의 체형을 분류하고 이들 체형을 분류하는 판별기준을 세우고자 하는 것이다. 이 연구에서 개발한 판별방법은 중년여성들의 체형을 간편하게 판별할 수 있도록 해주므로 이 방법을 활용하여 중년여성복을 제작할 경우, 소비자들은 인체적합도가 높은 의복을 구입 할 수 있고 의류업 체들은 이에 따른 매출증대를 가져올 수 있다. 연구의 진행절차와 이에 따른 결과는 다음과 같다. 1. 만 40세~59세 중년여성 279명에 대 한 인체 계측을 하였다. 인체 계측항목은 34개의 직접 계측항목과 측면사진 촬영을 통한 3개의 간접계측항목,11개의 지수치, 5개의 계산치 등의 총 53개 항목이다. 인체 계측치에 대한 통계분석 방법으로는 분산분석과 SNK검정, 판별분석 방법을 사용하였다. 2. 피험자는 몇 가지 체형으로 분류되었다. 상반신 체형분류는 인체측면 자세와 유방크기를 분류기준으로 하여 바른-유방중소 체형, 바른-유방대 체형, 젖힌-유방중소 체형 , 숙인/휜-유방중소 체형, 숙인/휜-유방대 체형의 5가지로 분류하였다. 하반신 체형분류는 배와 엉덩이의 돌출정도에 따라 분류하여 배정상-엉덩이정상 체형, 배 정상-엉덩이돌출 체형, 배돌출-엉덩이정상 체형 , 배돌출-엉덩이돌출 체형의 4가지로 분류하였다. 3. 분류된 체형은 다음의 판별변수에 따라 체형이 판별되었다. 상반신 체 형 의 판별변수는 앞품/뒤품, 가슴둘레/밑가슴둘레 , 앞길이/뒤 길이, 앞허리선$\longrightarrow$어깨선 길이/어깨선$\longrightarrow$뒤허 리선 길이의 4가지 항목이고, 하반신 판별변수는 엉덩이상부각도, 배 하부각도, 배상부 각도, 엉덩이둘레/엉덩이 최대둘레, 뒤엉덩이둘레의 5가지 항목이다. 상반신 체 형과 하반신 체형 판별함수 모두 70% 이상의 높은 적중률을 나타내었다.

유방암은 선진국형 질병으로 미국의 경우 가장 흔한 암으로 보고되고 있으며, 우리나라의 경우 과거에는 유방암 발생률이 낮았으나, 생활방식이 서구화되고 영양상태가 좋아지면서 점차 증가하고 있다. 유방암이 증가하는 이유는 명확히 밝혀지지는 않았지만, 서구화 되어가는 생활 패턴으로 초경 연령이 빨라지고, 폐경연령이 늦어지는 등 유방암 발생에 중요한 역할을 하는 여성호르몬에 노출되는 기간이 길면 길수록 유방암 발생이 증가하는 것으로 알려져 있다. 가족 중에 유방암이 있거나 출산하지 않을 경우 등에서도 유방암의 발생률이 다소 높다고 한다.(중략)

Wild ginseng pharmacopuncture was administered to 2 patients with pseudo-gynecomastia. Each patient received the treatment once a week, total 5 times. Outcome was measured by the comparison of photos which were taken before and after the treatment. One case showed significant difference in the breast shape and size after the treatment and the patient was satisfied with the result. However, the other case did not show noticeable change but subtle one, and satisfaction degree of the patient was also low. From the above cases, to figure out the effect of wild ginseng pharmacopuncture on pseudo-gynecomastia, further studies and reports on other affecting factors should be followed.

Gynecomastia is a benign enlargement of the male breast attributable to proliferation of the ductal elements. Gynecomastia has been rarely reported as an adverse effect of isoniazid therapy. We report the case of a 35-year-old man who was prescribed with isoniazid, rifampicin, ethambutol and pyrazinamide to treat pulmonary and lymphatic tuberculosis. After five months of treatment, the patient complained of painful engorgement in the bilateral breasts and the presence of male gynecomastia was confirmed with a physical examination and radiographical methods. The serum level of estradiol was also increased. Common causes of male gynecomastia were excluded through history taking and the laboratory findings. The anti-TB drugs were changed to a second line regimen due to radiographical progression and the intolerance of the patient to gynecomastia. Gynecomastia was relieved very slowly and a tender subareolar palpable mass decreased in size and consistency over five-month period after stopping the probable causative drug, isoniazid. From a review of the literature, gynecomastia has been shown to be a side effect of treatment with first line anti-tuberculosis drugs, and especially with isoniazid. We report the rare case.

Breast cancer is known as a disease that occurs in a lot of developed countries. However, in recent years, the incidence of Korea's modern woman is increased steadily. As well known, breast cancer usually occurs in women over 50. In the case of Korea, however, the incidence of 40s with young women is increased steadily than the West. Therefore, it is a very urgent task to build a manual to the accurate diagnosis of breast cancer in adult women in Korea. In this paper, we show how using data mining techniques to predict breast cancer. Data mining refers to the process of finding regular patterns or relationships among variables within the database. To this, sophisticated analysis using the model, you will find useful information that is easily revealed. In this paper, through experiments Deicion Tree Naive Bayes analysis techniques were compared using analysis techniques to diagnose breast cancer. Two algorithms was analyzed by applying C4.5 algorithm. Deicison Tree classification accuracy was fairly good. Naive Bayes classification method showed better accuracy compared to the Decision Tree method.

최근 몇 년간 방사선 의학진단과 관련된 연구가 한층 높아진 가운데 유방암은 여성의 암 중에서 1위를 차지하고 조기에 진단하고 치료하기 위한 국가적인 노력이 필요한 시점이다. 이렇듯 여성들의 유방암 발생빈도수가 급증하면서 대두 되고 있는 것이 조기 진단방법인 Mammography와 초음파 진단이며 그로인하여 발생하는 오진률 역시 많은 연구가 진행 되고 있다. 먼저 Mammography 및 초음파 진단의 문제점 보면 첫째 촬영과정에서의 오차, 둘째 영상의 선명도 ,셋째 전문의의 판독에 대한오차, 넷째 의사의 경험으로 진단함으로 표준화가 존재하지 않는다는 공통적인 문제점을 가지고 있다. 본 연구에서는 CAD 시스템의 프레임웍 및 요소 기술을 제시하여 의사의 진단을 보조적 수행이 보다 수월하도록 하고자 한다. 본 연구에서는 CAD시스템의 기능은 Detection기능(Image enhancement, Morphology, segment detection)과 Diagnosis기능( Neural Natwork등을 이용하여 증상을 판단)이다. 또한 과거 자료를 이용한 변이 및 변화를 예측함으로써 향후 있을 위험요소에 대비가 가능한 모듈과 전문의사가 대화형으로 빠르게 진단지식을 구축할 수 있는 지능형, 대화형 온라인 진단기능을 추가함으로써 외국의 CAD시스템과는 많은 차이가 있다고 볼 수 있다.

This study is a descriptive study to identify the factors affecting breast cancer screening behavior in women of childbearing age. The participants were 2,000 women between the ages of 19 and 40, and data collection was conducted through online and mobile surveys from September 2020 to August 2021. As a result of multivariable ordinal logistic regression analysis, age 20-29 (OR=2.145, CI=1.219-3.777), over 30 (OR=5.663, CI=2.784-11.521), annual income less than 10 million won (OR=1.606, CI=1.070-2.413), over 30 million won (OR=2.422, CI=1.550-3.785), family history of breast cancer (OR=2.421, CI=1.154-5.080), family history of ovarian cancer (OR=4.321, CI=1.382-13.516), subjective perception of health status was 'moderate' (OR=1.466, CI=1.064-2.020), and 'not healthy' (OR=1.854, CI=1.188-2.895) increased the breast cancer screening behavior. Therefore, based on this study, adequate policy should be adopted to strengthen the breast cancer screening behavior of young women of childbearing age.
