Diagnostic criteria for breast cancer liver metastasis

There are many methods for diagnosing breast cancer. The most commonly used one is mammography. The most accurate one is pathological diagnosis. Generally, imaging examination is performed first, and pathological examination is performed if there is any doubt. With the in-depth study of the close relationship between Western medicine pathological results and TCM syndrome types, TCM diagnosis of breast should not be underestimated. The ultimate goal of diagnosis is treatment. The combined diagnosis of Chinese and Western medicine will play a major role in promoting the reasonable integrated treatment of Chinese and Western medicine. Let me introduce it to you below.

Diagnosis of breast cancer - Western medicine imaging examination

Imaging examinations play an important role in the early detection of breast cancer.

① Ultrasound examination: microcalcification in breast masses, "burr" sign on the edge, and aspect ratio greater than 1 indicate the greatest possibility of cancer. Observing the peak blood flow velocity, average density of color pixels, and average blood vessel density of tumors through semi-quantitative methods and color capture technology is very helpful in distinguishing benign and malignant tumors. Penetrating blood vessels and MVD have a high sensitivity in diagnosing breast cancer.

②MRI examination: The use of paramagnetic contrast agent to enhance and then reconstruct MIP has a 100% display rate for breast cancer. MRS strongly indicates that the choline level in breast cancer tissue is increased, and the water/fat ratio is significantly greater than that of normal tissue, which is an important criterion for diagnosing breast cancer.

③ CT examination: Thin-layer scanning can detect cancer lesions with a diameter of 0.2 cm. The parameters related to breast cancer increase are closely related to MVD. It can better show the status of metastatic lymph nodes.

④X-ray examination: It has the greatest advantage in detecting breast cancer calcification foci. X-ray digital photography is helpful for CAD. MWA and CMRP technologies can improve the reliability of breast cancer diagnosis.

⑤ Infrared thermal image: Through the digital quantitative system, the temperature of the breast cancer hot zone is quantitatively analyzed, the temperature difference between the lesion center and the surrounding tissue is calibrated, and the benign or malignant tumor is judged.

⑥ Minimally invasive imaging: Ultrasound-guided biopsy of tiny lesions lacking imaging features, 3D CEPDU to improve the qualitative analysis of ultrasound-guided CT-guided biopsy
