Breast Screenings & Tests

Screening mammograms are X-ray exams of the breasts for women who have no breast symptoms or signs of breast cancer (such as a previous abnormal mammogram). Its goal is to find breast cancer when it’s too small to be felt by a woman or her doctor.

Finding breast cancers early (before they have grown and spread) greatly improves a woman’s chance for successful treatment.

A screening mammogram usually takes two X-ray pictures (views) of each breast. Some women, such as those with large breasts, may need to have more pictures to see as much breast tissue as possible.

A woman with a breast problem (for instance, a lump or nipple discharge) or an abnormal area found in a screening mammogram typically gets a diagnostic mammogram. Sometimes, diagnostic mammograms are done for screening in women without breast problems but were previously treated for breast cancer.

During a diagnostic mammogram, the images are reviewed by the radiologist while you wait, so more pictures can be taken if needed to look more closely at an area of concern. In some cases, special images known as spot views or magnification views are used to make a small area of concern easier to evaluate. Other types of imaging tests such as ultrasound may also be done in addition to the mammogram, depending on the type of problem and where it is in the breast.

A diagnostic mammogram is usually interpreted in one of three ways:

• It may reveal that an area that looked abnormal on a screening mammogram is actually normal. When this happens, the woman goes back to routine yearly screening.
• It could show that an area of concern probably is not cancer, but the radiologist may want to watch the area closely. When this happens it’s common to ask the woman to return to be re-checked, usually in four to six months.
• The results could also suggest that a biopsy is needed to find out if the abnormal area is cancer. If your doctor recommends a biopsy, it does not mean that you have cancer.

Breast ultrasound (ABUS) is available at St. Luke’s Regional Breast Centers in Center Valley and Stroudsburg as a supplemental breast cancer screening exam. Specifically-designed and FDA-approved for women with dense breast tissue, ABUS can provide a clearer, more accurate evaluation of dense breast tissue and can be used to complement screening mammography. ABUS uses sound waves, not radiation, to create state-of-the-art 3D images of the breast tissue.

This non-invasive exam is used to gain information about breast abnormalities detected with mammography, physical exam or other breast imaging. MRI also may be used for breast implant evaluation, staging breast cancer, evaluating treatment options and follow-up after treatment is complete. MRI also may be an option for patients with dense breasts and with a strong family history of breast cancer. Please discuss with your physician if breast MRI is appropriate for you.

This is a test that sends high-frequency sound waves into the breast. The pattern from the sound waves is converted into an image of the interior of the breast to help distinguish between tumors, which are solid and cysts, which are filled with fluid.

St. Luke's uses the genetic profile of an individual's breast cancer to help determine if chemotherapy should be given as an adjuvant therapy.

This is a technique used prior to surgery to locate and mark a mammographic area of concern in the breast that cannot be felt. Such areas include masses and microcalcifications.

Under ultrasound guidance, the physician locates the breast abnormality and uses a specially guided needle to extract small samples of tissue while the patient is under local anesthesia. The samples are sent to the laboratory for evaluation.

This is an examination using an ultrasound-guided needle to remove fluid from a cyst.
