Diagnostic testing in patients with breast cancer not only includes breast imaging technologies but in general, also includes hematologic and chemistry testing of the patient. The primary diagnostic modalities of the breast include 3–D digital mammography; breast ultrasound; and breast MRI examination.

The treatment of breast cancer often requires several different modalities of treatment. Surgery is fundamental in removing cancers from the breast or the entire breast as part of the local regional control of cancer. If patients undergo breast conservation (“lumpectomy”) then the majority of these patients do require some form of radiation therapy. Patients with estrogen receptor-positive invasive cancers need to be treated with anti-hormonal therapy for a minimum of 5 years. Chemotherapy in this day and age is mandatory in patients with triple-negative and HER-2/neu positive breast cancers.

All newly diagnosed breast cancer patients should be treated by a multidisciplinary team of specialists. That is the contemporary standard of care.
