It is a specialized X Ray of the breasts with low voltage and high ampere beams. Breasts are compressed between the plates. There are two standard views – Crainocaudal and Mediolateral. Additional views are taken if required.
It is an X ray with low dose of radiation, hence no risk of Malignancy.
It should be done so that lesions are detected at a very early stage when they are not even clinically palpable and at a stage when the disease is curable.
It can differentiate between benign(non-cancerous) and malignant(cancerous) breast lumps.
Ultrasonography is usually combined with mammography as a protocol now. It detects small lumps and cysts at an early stage. It is also useful to take biopsy- FNAC and Core Biopsy. It is also combined with elastography.
A newer technique called Vaccum Assisted Biopsy (VAB) is a very safe and minimally invasive procedure, wherein the breast tissue is taken and sent for biopsy. Even a very small lump, which is not palpable clinically, but seen under Breast imaging, can be removed and biopsied.
MR Mammogram is done for Characterization of an indeterminate lesion after a full assessment with mammography, ultrasonography, and physical examination. It is advised for evaluation of suspected multifocal or bilateral lesions. It is done in women with high risk and genetic predisposition.
