Currently breast cancer is tending to rejuvenate. According to statistics of the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO), breast cancer is the most common type of cancer in women. In Vietnam, in 2018, there were more than 15,000 new cases, including more than 6,000 deaths from breast cancer. Ultrasound of the mammary glands determines breast calcification plays an important role in the prevention and treatment of early diseases.
1. What is mammary gland calcification?
Benign breast calcification is identified by a typical mammary gland ultrasound that is round, large and coarse with a smooth and recognizable shoreline than malignant calcification. Breast calcification associated with melanoma (as well as many benign calcifications) is usually very small and an exaggerated glass should be used for better visibility.
When it is not possible to give a specific cause of the disease, the description of breast calcification should have both their edicts and distribution. However, it is advisable to report them if the doctor reading the film is concerned that other movie readers may mis-explain.
2. What is mammogram ultrasound?
Ultrasound of the mammary gland, also known as mammography,is the English term mammography. Ultrasound of the mammary glands is a technique that uses ultrasound waves projected through the mammary glands to record mammary gland images to reproduce mammary gland images and structures, helping to detect erform abnormalities of the mammary glands.
Ultrasound of the mammary glands can be performed in the usual way as a doctor in person for examination or by 3D automatic breast ultrasound. With 3D automatic mammograms, patients will be examined with an automatic scanner. After that, the specialist will analyze the image obtained to find the abnormalities of the mammary glands.
The purpose of mammogram ultrasound is to detect lesions of the mammary glands. Ultrasound of the mammary glands is being applied worldwide for diagnosis, early detection, monitoring of abnormalities in the mammary glands, especially breast cancer.
3. Benign breast tumor images on ultrasound
Numerous studies have shown that benign breast tumors often have the following signs on ultrasound:
- The shore is clear, soft;
- Lesion limit: The face is clearly and thinly separated from the next healthy tissue (secondary signs);
- Calcification: Coarse calcification;
- Direction: Parallel;
- "structure: Drum (cystic) response, thick response, later sound changes: amperage, homage or slight decrease in sound compared to mammary gland moym;
- Has a thin shell;
- The ellipse in which the axis is large parallel to the surface of the skin;
- The block does not cause contraction of neighboring structures;
- There are no signs suggesting malignanity;
Classification of benign breast tumors:
- Type 1- Mere cyst: The cyst is round or oval, the shore is clear, the drum is negative, there is a brightening to the back;
- Type 2- Cystic complications: There are mere cystic-like features, except for negative structural characteristics, which inside often have a negative structure that settles into levels.
- Type 3- Cyst complex: The walls are thick, the walls are thick and/ or somewhat densely organized inside;
4. Malignant breast tumor characteristics
- shape:
- Uneven (main signs);
- round.
- Direction: Non-parallel (main sign);
- Shoreline:
- Thorny rewinds (main signs);
- Unknown (secondary signs);
- Bending angles (secondary signs);
- Small poly arc (secondary sign).
- Injury limit: Unknown limit with thick response border (secondary sign);
- Response structure:
- Very poor response (secondary signs);
- Mixed feedback (secondary signs).
- Change the back sound: Create a back shadow (secondary sign);
- Calcification:
- Micro-calcification (main signs);
- Ultrasonic Doppler;
- Perfussing in the tumour;
- RI > 0.83, PI > 1.6.
- Meta meta metalysed lymphadenopathy:
- Short diameter > 1cm;
- 3mm thick > shell;
- Loss of umbilical cord;
- Perfusion outside the umbilical cord;
- Multi-arc shoreline.
5. Where is the mammary gland ultrasound good?
The early 2020 breast cancer screening package will be of great help to the treatment process. Early intervention by methods such as medication, radiotherapy, chemotherapy, surgery, end hormones, biology … can minimize the effects of the disease, slow down the development of the disease, especially save the life of breast cancer patients.
Currently, on vinmec International Health Hub system, there are modern mammograms to help diagnose calcified nodules early. Share99 uses invenia ABUS 3D mammogram device – is the most advanced automatic ultrasound device in the world today in breast cancer screening with many outstanding advantages over other ultrasound techniques:
- The system is capable of screening, diagnosis, monitoring before, after, treating mammary gland diseases and detecting breast cancer with up to 90% accuracy. In addition, the mammogram system helps diagnose breast calcification nodules early, increasing the likelihood of detecting breast cancer at a very early stage without clinical manifestations;
- Integrated ARFI tissue elasticity technology, tissue hardness assessment helps to verify and complement the results on 3Dmammary gland ultrasound imaging, enhancing accuracy during diagnosis;
- The 3D mammary gland ultrasound system helps to create anotomical cross-sectiones that currently traditional ultrasonic systems do not perform;
- Detect and identify small-sized lesions to support effective disease monitoring and treatment;
- There is data assessing breast damage quickly, safe from non-invasive and non-radioactive contamination, so pregnant women can use this system.
