View detailsMammography
Mammography is a low-dose X-ray examination technique for the breast. It offers advantages such as simplicity, ease of use, non-invasiveness, low cost, repeatability, and diagnostic accuracy. It can detect lumps that cannot be felt by a doctor, diagnose early breast cancer, and localize, characterize, and monitor breast lesions. The combination of mammography and breast ultrasound is a commonly used breast examination method internationally. Interpretation of BI-RADS classification in mammography reports: Category 0: Requires additional imaging evaluation. Category 1: Negative. Category 2: Benign finding. Category 3: Probably benign finding, short-interval follow-up suggested. Category 4: Suspicious abnormality, biopsy recommended. Category 4A: Low suspicion for malignancy. Category 4B: Moderate suspicion for malignancy. Category 4C: High suspicion for malignancy but not definite. Category 5: Highly suggestive of malignancy. Category 6: Known biopsy-proven malignancy.
View detailsBreast ultrasound
Breast ultrasound examination is a technique that uses a high-frequency ultrasound probe to perform a comprehensive and systematic ultrasound scan of both breasts (including the axilla). It mainly includes: 2D ultrasound: This is the black and white ultrasound we usually see. Color Doppler ultrasound: This is what we usually call color ultrasound. Elastography: This is mainly used to evaluate the hardness of space-occupying lesions in the breast. Generally, malignant tumors are harder, and benign tumors are softer. Differences between breast ultrasound and mammography, X-ray, and MRI examinations Mammography can accurately display calcifications and spicules, especially microcalcifications, with a higher detection rate than ultrasound. However, it involves radiation and is not suitable for repeated examinations. Tumors at the edge of the breast are easily missed. MRI has high resolution for soft tissue lesions, but 5% to 12% of invasive cancers cannot be detected. Moreover, MRI is expensive and not suitable for repeated examinations. Ultrasound examination is radiation-free, harmless, and inexpensive. It is suitable for general screening and dynamic follow-up of suspicious lesions. It can observe the blood flow of suspicious masses, and its display of axillary lymph nodes is superior to mammography. Interpretation of Breast BI-RADS Classification Results Category 0: Indicates the need for other auxiliary examinations. Category 1: Indicates no mass. Category 2: Indicates the mass is benign. Category 3: Indicates the mass is likely benign, but re-examination and follow-up are required in the short term. Category 4: Indicates the mass is suspicious for malignancy, and biopsy is recommended. Category 4A: Low suspicion for malignancy. Category 4B: Moderate suspicion for malignancy. Category 4C: High suspicion for malignancy but not definite. Category 5: Indicates the mass is highly suspicious for malignancy. Category 6: Indicates the mass has been pathologically confirmed as malignant.
Paget's disease of the breast
Mammary Paget's disease, also known as mammary eczematous carcinoma, is a special type of cancer originating from epithelial cells. It manifests as eczematous skin lesions of the breast, predominantly affecting the unilateral nipple and areola, and gradually expanding outwards from there. Based on clinical manifestations, mammary Paget's disease is classified into three types: nipple erosion type, mass type, and nipple erosion with mass type. This disease is clinically rare and predominantly affects postmenopausal women, especially those over 60 years old. In the early stages, red patches, eczema, or small papules may be observed. In the middle stages, symptoms such as itching, burning sensation, and pain may appear. In the late stages, ulcers, erosions, and bleeding may occur.
View detailsBreast sarcoma
Breast sarcoma refers to a malignant tumor originating from the mesenchymal tissue of the breast. Breast sarcoma can be primary or secondary, often occurring after radiotherapy. According to its tissue origin, it can be divided into the following 2 types: Mesenchymal tissue type: mainly includes breast liposarcoma, angiosarcoma, and fibrosarcoma. Mixed tissue type: mainly includes breast phyllodes tumor and carcinosarcoma. This disease is common in people aged 25 to 50, mostly in women, and rarely in men. The main symptoms include a painless lump in the breast, which grows rapidly and is large, and the breast skin becomes shiny and thin.
View detailsPolymastia and polythelia
Polymastia and supernumerary nipples are congenital developmental anomalies, referring to the presence of one or more additional breasts or nipples in addition to the normal pair of breasts. They are most commonly found in both axillae, followed by the inferomedial aspect of both breasts.
View detailsMammary duct ectasia
Mammary duct ectasia is a non-puerperal mastitis characterized by inflammation caused by deformation and dilation of the lactiferous ducts beneath the nipple. This condition is common in middle-aged and elderly women, primarily presenting with nipple discharge and nipple itching. Some patients may also experience breast pain and redness and swelling around the nipple and areola.
View detailsBreast cyst
Breast cysts are typically benign lesions in the female breast, characterized by fluid-filled sacs. They can occur in one or both breasts and may be solitary or multiple. This condition is common in middle-aged women, particularly those between 35 and 50 years old. The main symptom is the presence of round or oval lumps in the breast with clear boundaries.
View detailsIntraductal papilloma of breast
The female breast has 15 to 20 lactiferous ducts, which open at the nipple. Intraductal papilloma of the breast is a benign tumor originating from the ductal epithelium. It is a common benign breast tumor in women and has a certain rate of malignant transformation. This disease can be divided into two types: Central intraductal papilloma (solitary): This is more common clinically. It frequently occurs in multiparous women, especially those aged 40 to 50. It originates from the large ducts, usually located subareolarly, and does not involve the terminal ductal-lobular unit. Peripheral intraductal papilloma (multiple): This originates from the terminal ductal-lobular unit. This disease generally has no subjective symptoms. It is often noticed due to nipple discharge staining underwear, which can be bloody, dark brown, or yellow.
