Experts explain the key points of breast cancer diagnosis

The early symptoms of breast cancer are not obvious, which will cause many patients to ignore them. If you find them, you must go to the hospital for examination in time. Here we will introduce the diagnosis methods of breast cancer to you. I hope you will have a better understanding of breast cancer.

1. Molybdenum target and dry plate radiography: Masses with different shapes, increased density, and irregular edges can be seen, some with radial burrs, accompanied by fine calcification and thickened blood vessels. Some can also show secondary symptoms such as thickened skin and nipple retraction. Catheter angiography can be performed to assist in the diagnosis of intraductal lesions.

2. B-ultrasound scan: It is helpful to distinguish whether the mass is cystic or solid. Breast cancer often presents as a regular low-echo mass, but also as an overly echogenic focus, irregular solid destruction of the echo band or an atypical cystic mass, but it needs to be separated from the cystic hyperplasia. B-ultrasound is not very valuable for the diagnosis of early breast cancer.

3. Infrared thermal imaging examination: Some breast cancer tumors often have increased blood vessels and increased surface temperature, which is used as a reference for comprehensive diagnosis in clinical practice.

4. CT scan: As a supplement to mammography, it helps detect malignant lesions and distant metastases in dense breasts. It is rarely used because of its high price.

5. Transillumination: After cancerous tissue preferentially absorbs near-infrared rays, it presents different color images of brown, brown or black to assist clinical diagnosis. This is a commonly used method for diagnosing breast cancer.

6. Tumor marker determination: For example, carcinoembryonic antigen (CEA) determination is used as an auxiliary diagnosis, especially for patients with bone and visceral metastasis. In addition, serum prolactin, calcitonin, lactate dehydrogenase isoenzyme, etc. can all be used as diagnostic references.

7. Pathological diagnosis: This is the most reliable diagnostic method. Commonly used methods include preoperative nipple discharge smear cytology examination, fine needle aspiration cytology examination of the mass, and intraoperative frozen section examination of the mass excision.

The above is an introduction to the diagnosis of breast cancer. After the diagnosis is confirmed, the correct treatment method must be selected. If you want to know more about breast cancer, please consult online experts.
