Early diagnosis of breast cancer

Breast cancer is one of the most common malignant tumors in the world, and its prognosis is closely related to the time of diagnosis. Early detection and treatment of breast cancer can significantly improve survival rates and survival. Therefore, it is very important to understand and master the methods of early diagnosis of breast cancer. Clinical examination is the basic method for early diagnosis of breast cancer. By looking at and touching the breast, the doctor checks for lumps, skin changes, nipple discharge and other symptoms. Regular clinical examination, especially for high-risk groups, can help to detect abnormalities early. Imaging examination of breast color Doppler ultrasound: Color Doppler ultrasound is a cost-effective imaging examination method, no radiation, can be repeated, especially suitable for Asian women with dense breast tissue. Through color Doppler ultrasound, the fine structure inside the breast can be observed, and potential masses or abnormalities can be found. Mammography: Mammography is another commonly used imaging method, suitable for women over 40 years of age as a means of annual screening. It is able to spot tiny calcifications in the breast that may be a sign of early breast cancer. Breast magnetic resonance imaging (MRI): Breast MRI is a more sensitive screening method for some high-risk groups, such as BRCA gene mutation carriers. It can detect small lesions that are difficult to detect by other imaging examinations. In addition to imaging examination, biomarker detection is also one of the research directions of early diagnosis of breast cancer. Detection of specific protein or gene expression levels in the blood is expected to detect abnormalities early in tumor formation. However, biomarker detection has not been widely used in clinical practice, and further research is needed. In addition to professional medical examination, female friends should also learn self-examination. Monthly self-examination after the end of menstruation to observe whether there are breast lumps, skin depressions, nipple discharge and other abnormal phenomena. Once abnormalities are found, they should seek medical treatment in time. Early diagnosis of breast cancer is essential to improve survival rates. Early breast cancer can be effectively detected through regular clinical physical examination, imaging examination and self-examination. Female friends should raise health awareness, actively participate in screening, and protect their own health.
