Mammograms, or mammograms, are the preferred screening test for breast disease and are painless and convenient. Often doctors will actively recommend mammography if the appropriate indications exist, but if they do not recommend mammography they may do so because it is not necessary or because of the patient’s personal circumstances. Mammography is radioactive and may cause cellular mutations, but mammography is a low level of radiation and is normally very safe. Mammography is not recommended when the breast is abnormally developed, or during pregnancy or lactation. It is also not recommended if the interval between examinations is too short, such as less than 3 months. In some patients with advanced breast cancer, the diagnosis is clear and the doctor will consider the family’s opinion if the family is under financial pressure. Some women are too young, have abundant glands or have small breasts, so it is not easy to operate the test and the lesion cannot be easily detected. When a woman is premenstruating or menstruating, her breasts may become engorged and edematous, which can affect the results of the examination and make it easier to squeeze and painful, so we may recommend rescheduling the examination if not necessary. Certain diseases, such as inflammatory lumps, are squeezed and infection may spread further. Therefore, the suitability of a mammogram requires patients to actively follow their doctor’s advice and have full trust in them to help the disease be better diagnosed and treated.
