A patient can expect to receive an injection of radiopharmaceutical agent intravenously in the arm contralateral to the breast under investigation. After waiting 5–10 minutes, the breast tissue is placed into the MBI system and a series of images are obtained. Imaging time for both breasts is approximately 40 minutes.
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
The grading of a cancer in the breast depends on the microscopic similarity of breast cancer cells to normal breast tissue, and classifies the cancer as well differentiated (low-grade), moderately differentiated (intermediate-grade), and poorly differentiated (high-grade), reflecting progressively less normal appearing cells that have a ...

There are many reasons why a doctor may order a breast biopsy. [7] Typical indications include: A suspicious area on mammography or ultrasound. [9] This may include: Microcalcifications on MRI. [10] BI-RADS score of 4 or 5 on mammography, ultrasound, or MRI. [11] A suspicious hard palpable lump [9]
The Breast Imaging-Reporting and Data System (BI-RADS) is a quality assurance tool originally designed for use with mammography.The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology (ACR).
It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned ...
A score of 1 is assigned to a benign test result, 2 applies to a suspicious test result, and 3 applies to a malignant result. The sum of the scores of all three procedures is the triple test score. If the total summed score from the three tests is 3 to 4 then the diagnosis is most likely benign. A total summed score of 5 is considered suspicious.
