Imaging Tests to Look for Breast Cancer Spread
If you have been diagnosed with breast cancer, you might need more imaging tests. Your doctor will talk with you about which of these tests you may need. Imaging tests use x-rays, magnetic fields, sound waves, or radioactive substances to create pictures of the inside of your body. Imaging tests might be done for a number of reasons including:
Chest x-rayA chest x-ray may be done to see if the cancer has spread to your lungs. Computed tomography (CT) scanA CT scan uses x-rays to make detailed cross-sectional images of your body. Instead of taking 1 or 2 pictures, like a regular x-ray, a CT scanner takes many pictures and a computer then combines them to show a slice of the part of your body being studied. This test is most often used to look at the chest and/or belly (abdomen) to see if breast cancer has spread to other organs, like the lungs or liver. CT-guided needle biopsy: If a suspected area of cancer is deep within your body, a CT scan might be used to guide a biopsy needle into this area to get a tissue sample to check for cancer. Magnetic resonance imaging (MRI) scanLike CT scans, MRI scans show detailed images of soft tissues in the body. But MRI scans use radio waves and strong magnets instead of x-rays. This test can be used to look at the breasts or other parts of the body, such as the brain or spinal cord to look for possible cancer spread. UltrasoundUltrasound (ultrasonography) uses sound waves to create an image on a video screen. A small microphone-like instrument called a transducer that gives off sound waves is moved over the skin surface and picks up the echoes as they bounce off tissues. A computer turns these echoes into an image on the screen. An ultrasound can be done over a breast or in the underarm area, or even the liver. Positron emission tomography (PET) scanFor a PET scan, a slightly radioactive form of sugar (known as FDG) is injected into the blood and collects mainly in cancer cells. PET/CT scan: Often a PET scan is combined with a CT scan using a special machine that can do both at the same time. This lets the doctor compare areas of higher radioactivity on the PET scan with a more detailed picture on the CT scan. Bone scanA bone scan can help show if the cancer has spread to your bones. A small amount of low-level radioactive material is injected into the blood and collects mainly in abnormal areas of bone. It can show all of the bones of your body at the same time and can find small areas of cancer spread not seen on plain x-ray. American Cancer Society medical information is copyrighted material.

Skip to Content Breast cancer is sometimes found after symptoms appear, but many women with breast cancer have no symptoms. This is why regular breast cancer screening is so important. Learn more. Signs and Symptoms of Breast CancerThe most common symptom of breast cancer is a new lump or mass, but other symptoms are also possible. It's important to have any breast change checked by a health care provider.
BiopsyA biopsy is done when mammograms, other imaging tests, or a physical exam shows a breast change that may be cancer. A biopsy is the only way to know for sure if it’s
cancer.
Finding breast cancer during pregnancyBreast cancer during pregnancy is rare. But if you find a lump or notice any unusual changes in your breasts that concern you, tell your doctor or nurse right away.
Diagnosis Cancer If cancer is found in your breast, your doctor will assess the stage or extent of the disease. Staging is an effort to determine if the cancer has spread and, if so, to what parts of the body. Your doctor may use blood and imaging tests to learn the stage of the disease. Treatment decisions depend on these findings. Read Basic Facts about Breast Health to learn more about the staging system. The first step is usually a physical exam by a doctor or nurse practitioner. Mammography and ultrasound may be part of the exam. On the basis of these evaluations, the decision may be made to perform a tissue biopsy. ImagingImaging is used to diagnose breast cancer and to evaluate the stage and extent of disease. Three types of imaging are used — mammography, ultrasonography and breast magnetic resonance imaging (MRI). Based on these exams, your doctor may recommend further tests or therapy, or determine that not treatment is necessary.
BiopsyOne way to find out if a breast lump or abnormal tissue is cancer is by having a biopsy. During a biopsy, a surgeon, a pathologist or a radiologist removes a portion or all of the suspicious tissue. The suspicious tissue is examined under a microscope by a pathologist who checks for cancer cells and makes the diagnosis. The following are descriptions of different types of biopsies.
Decision-making consultationIf you are diagnosed with breast cancer, Collaborative Care services at the UCSF Carol Franc Buck Breast Care Center can help you effectively communicate with your doctors as you navigate the series of complex decisions surrounding your treatment options.
