Breast cancer is one of the most common malignant tumors in women. Early detection and treatment are crucial to improve the survival rate and quality of life of patients. Traditional screening methods for breast cancer mainly rely on mammography, that is, mammogram. However, for young women or women with high breast tissue density, the sensitivity of Mammogram may be lower. Medical ultrasonic scanner, as a non radiation and non-invasive imaging technology, has become one of the important means for early detection of breast cancer. This article will deeply discuss how ultrasonic scanners can help early detection of breast cancer, and analyze its advantages and limitations in breast cancer screening.

1、 The principle and technical characteristics of ultrasonic scanners

Medical ultrasound scanner is a device that utilizes sound wave imaging to emit high-frequency sound waves into breast tissue and form images by receiving echo signals. It has the following technical characteristics:

1. High resolution imaging: Ultrasound scanners can display the fine structures and abnormalities of breast tissue at high resolution.

2. Non invasive: Ultrasound imaging does not require puncture or injection of contrast agents, making it more comfortable and safe for patients.

3. Real time imaging: Ultrasound scanners can observe the morphology and blood flow of breast tissue in real-time, making it easier for doctors to evaluate and analyze abnormal areas.

2、 Application of ultrasonic scanner in the diagnosis of early breast cancer

Ultrasonic scanner plays an important role in the diagnosis of early breast cancer. Common applications include:

1. Detection of breast lumps: ultrasonic scanners can help doctors detect lumps in breast tissue, and help doctors judge whether a lump is breast cancer by analyzing the shape, boundary, size, internal echo and other characteristics of the lump.

2. Evaluation of breast cystic lesions: Ultrasound scanners can identify breast cystic lesions and help doctors determine whether cystic lesions require further examination and treatment by observing their size, shape, echo, and wall thickness.

3. Evaluation of breast hyperplasia: Through ultrasound imaging, the proliferation of breast tissue can be evaluated, and combined with other clinical data, it can help doctors determine whether hyperplasia may evolve into malignant tumors.

4. Detection of lymph node metastasis: ultrasonic scanner can evaluate whether there is lymph node metastasis in breast cancer, and help doctors judge the disease stage and treatment plan by observing the size, shape, boundary, echo and other characteristics of lymph nodes.

3、 Advantages and limitations of ultrasound scanner in breast cancer screening

Ultrasonic scanner has the following advantages in breast cancer screening:

For young women and women with high breast tissue density, ultrasound scanners have higher sensitivity and can achieve early diagnosis and treatment.

2. Ultrasound scanners can provide more information, such as the blood flow of breast tissue, which can help evaluate the malignancy and prognosis of tumors.

However, ultrasound scanners also have some limitations in breast cancer screening:

1. Ultrasound imaging may be difficult to detect and locate small breast cancer lesions.

2. Ultrasound scanner cannot replace Mammogram as the first choice method for breast cancer screening, and the combination of the two can improve the early detection rate of breast cancer.

Conclusion:

Ultrasonic scanner, as a non radiation and non-invasive imaging technology, has become one of the important tools for early detection of breast cancer. Its high resolution, non-invasive and real-time characteristics make the diagnosis and treatment of breast cancer more accurate and reliable. However, ultrasound scanner still has some limitations in breast cancer screening, which needs further optimization and improvement. In the future, with the development of medical technology, we will have a deeper understanding and understanding of the use and application of ultrasonic scanners, bringing more hope for the prevention and treatment of early breast cancer.
