The reading of mammogram film can tell the severity of the patient’s breast. The correct reading of the film needs to be seen from the following aspects: First, it needs to see how large the breast gland is, as an approximate criterion to determine whether the breast gland is in hyperplasia or has started to degenerate, and it also needs to pay attention to whether there are nodules of equal density in it. Second, we need to see how evenly distributed the breast glands are, such as whether there are hard lumps, size, location and whether the borders are clear. The size of the calcified spots in the breast can be used to infer the benign and malignant nature of the calcified spots. The size and number of local lymph nodes in the film should be taken into account. Considering that the information seen only from the mammogram results is limited and cannot be used as an accurate criterion for judgment, it is necessary to combine with other examinations for judgment.
