Getting a breast biopsy does not necessarily indicate that it is very serious.

A breast biopsy can be used to determine the nature of breast space-occupying lesions, such as whether they are benign or malignant. Before the breast biopsy report is available, it cannot be confirmed that it is definitely a serious breast disease. Therefore, getting a breast biopsy does not necessarily indicate that it is very serious; it could be a benign breast disease or a malignant breast space-occupying lesion—this depends on the results of the breast biopsy.

In the examination of breast diseases, color Doppler ultrasound, mammography, and breast biopsy are all commonly used clinical diagnostic methods. However, the results of color Doppler ultrasound and mammography can only serve as auxiliary tools for diagnosing breast diseases and cannot be used as definitive evidence to determine whether a breast lesion is benign or malignant. To accurately assess the benign or malignant nature of a suspicious breast lesion, the results of a breast biopsy must be relied upon.
