Breast patients understand why to do the necessary examination? 1, first of all, let’s take an example: there was a patient who did not suspect breast cancer by ultrasound and molybdenum target, but suspected malignancy by palpation, and finally diagnosed breast cancer by surgical biopsy. 2, palpation can only touch the larger lumps, small cysts and nodules can not be touched at all, and further diagnosis must be made with the help of color ultrasound. If it is economically difficult to do only one test, as long as the lumps are not touched, the molybdenum target can be chosen, but color ultrasound will be supplemented in the future. 3, the molybdenum target did not find abnormalities, does not mean that there is no problem, the follow-up should be followed up. 4 Some patients do not have further examination, do not have surgery, do not have puncture, do not have follow-up, and do not follow the doctor’s will. Once a patient in a tertiary hospital mammography clinic for six months, only do ultrasound, was diagnosed with ordinary hyperplasia, and then by my department for molybdenum target ultrasound examination, preoperative diagnosed as breast cancer, surgery confirmed with the judgment is fully consistent. Doctors are not immortals, we must use the results of modern equipment, combined with medical history, physical examination results of a comprehensive analysis in order to arrive at a correct diagnosis, can not omit the necessary checks, resulting in misdiagnosis and omission of the evil consequences. Patients should understand the significance of the examination, which is a kind of performance of their own responsibility.
