Tests & Screenings

Early detection and proper diagnosis of your breast condition is the first step in proper treatment. At Fountain Valley Regional Hospital and Medical Center, we offer a range of screenings and tests to help reach that diagnosis. Among them are:

3D Mammography

3D mammography is a procedure that uses multiple low-dose images to create a 3-dimensional view of the breast. It allows the doctor to examine the breast layer by layer. Any abnormalities are more visible, since they are not hidden by the tissue above and below.


A biopsy is the removal of a small piece of tissue, which is then tested in a lab for signs of disease or infection. Doctors typically order a biopsy when another medical test suggests that a body tissue is not normal.

Blood marker tests

Blood marker tests are often used in patients with cancer or tumors to help determine cancer activity throughout the body. Cancers and tumors often produce a protein found in the blood that can serve as a marker for the cancer.

Breast MRI

Breast MRI is a diagnostic procedure that uses large magnets, radiofrequencies and a computer to produce a detailed image of the breast. This image is used to check for signs of cancer and other abnormalities.

Breast physical exam

Breast physical exams are performed in a doctor's office and are frequently part of a woman's annual physical exam. Breast exams are used to check for signs of cancer and nipple discharge; they are also performed if a patient complains of breast pain.

Ductal lavage

Ductal lavage is a screening tool used to detect breast cancer in women who are at high risk for developing the disease. During the procedure, cells are collected from the milk ducts to screen for cancer cells.

FISH test

Fluorescence in situ hybridization is also referred to as a FISH test. For breast cancer, this test is performed on tissue removed from the breast to help determine the genetic makeup of the cells.

IHC tests

An IHC test is crucial for planning the treatment of a breast cancer patient. This test helps to determine if a tumor is fueled by estrogen or progesterone.

Inform HER2 dual ISH

An inform HER2 duel ISH test is intended to determine whether a tumor is fueled by estrogen or progesterone. This can play a crucial role in developing a treatment plan for a breast cancer patient.

MammaPrint test

A MammaPrint test is a genetic test that analyzes the activity of certain genes during the early stages of breast cancer. This test can be used for all forms of breast cancer and can play an important role in determining the course of treatment following surgery.

Mammostrat test

A mammostrat test is a genetic test used to determine a woman's risk of developing breast cancer for a second time. This test can be beneficial in planning treatment and may even allow some women to forgo chemotherapy.


MarginProbe delivers real-time cancer detection while a patient is in the operating room. This device allows doctors to preserve as much of the breast as possible while removing cancerous cells.

Molecular breast imaging

Molecular breast imaging is a nuclear medicine test used to detect breast cancer. This diagnostic procedure uses small-semiconductor cameras to produce high-resolution images of the breasts.

Oncotype DX test

This oncology test is used to help predict the changes of breast cancer recurring. It analyzes a group of genes to determine how likely it is for the cancer to return.

PET scans

A positron emission tomography (or PET) scan is an imaging test that uses a radioactive substance called a tracer to look for disease (cancer) in the body. A PET scan shows how organs and tissues are functioning.

Prosigna breast cancer prognostic gene signature assay

Used in the early stages of the disease, Prosigna is a genetic test used to determine risk factor. This test looks at how likely the disease is to advance into advanced-stage cancer.


Ultrasound is a noninvasive diagnostic test that uses high-frequency sound waves to produce images of various organs and structures throughout the body. When performed on the breast, it can be used to check the tissues for signs of cancer.
