Breast cancer though as the number one killer in the incidence of malignant tumors in women today. However, the current improvement of diagnosis and treatment means for breast cancer has conquered its breast cancer in a controllable situation and cure is also possible. How to detect it early is the key to treatment, and the examination means currently used: 1. Color ultrasound examination: low cost, high sensitivity, poor specificity. It is closely related to the experience of the doctor doing the ultrasound diagnosis. 2, mammography: slightly higher cost, poor sensitivity, high specificity. This test can be done if there is a clear mass and the nature of the mass needs to be identified. In particular, it should be noted that not all patients need this test without evidence of abuse. It is not right for individual doctors to suggest that patients go to a large hospital for this test without knowing the indications for mammography. 3, MRI (magnetic resonance imaging) examination: belongs to the examination of high accuracy, its cost is relatively high means, compared with the above two examination methods, the accuracy is also high. Plain scan+enhancement can greatly improve the detection rate of early breast cancer, especially early and multiple lesions. It can also detect the lymph nodes in the axilla. 4.Lump puncture biopsy: It is a special method that can provide pathomorphological and immunohistochemical results of patient’s lesions, and in turn, it is a better method that can provide the basis for treatment. The above tests need to be used in combination with the patient’s physical examination in order to produce appropriate and realistic results and to detect problems early. Based on this evidence, the doctor will use the “heart” to analyze the condition and all the results of the tests to reach a definitive conclusion that is consistent with the condition. This is not like some patients or family members who search the Internet with a test result and take it out of context to make a judgment, which results in blinding themselves and scaring themselves and their family members with unrealistic results. As for breast cancer, many people may be confused and just go to the internet to read how bad and scary the disease is. However, breast cancer is a known malignant tumor that can be cured very well. The concept of breast cancer as a curable “chronic disease” has been accepted by everyone, as long as the patient insists on receiving the correct treatment guidance from the doctor, according to the patient’s clinical stage, pathological stage, immunohistochemistry and biological characteristics of the tumor, the scientific treatment (including surgery, chemotherapy, radiotherapy, endocrine therapy, targeted therapy, etc.) will be formulated. Thus, we will definitely treat some breast cancer patients as a kind of chronic disease, stratify and carry out individualized management throughout the whole process, and most patients believe that they will achieve good results. Instead of one-sided understanding of the negative effects of surgery, radiotherapy and chemotherapy, which delay the treatment time. Remind not to believe in the so-called simply unreliable so-called what secret formula Daisy and other words it. Lest delay the formal treatment. Since the treatment treatment must be standardized, individualized, humane, precise, in order to ensure maximum efficacy.
