You will have ongoing tests to monitor your health and response to your treatment(s).

ECG (electrocardiogram) is a checkup of your heart. The ECG is a test of the electrical conduction in the heart, and the coordination of muscular activity as a result of conduction.

MUGA scan, also known as multigated acquisition scan, is another test to check your heart's health. Specifically, a MUGA scan will help see how well your heart is pumping blood.

Echo test, also called an echocardiogram, is a test that uses sound waves (ultrasound) to measure the function of heart valves and check the blood flow of your heart.

Blood test helps determine if your liver and kidneys are working normally. It also helps see how your bone marrow is working (bone marrow controls the production of normal blood cells). Note that a blood test does not specifically check for cancer cells.

Chest x-ray helps your doctor check the health of your lungs and for any sign of benign or malignant lung disease, or recurrent cancer. Depending on your age and stage of breast cancer you may not need to have a chest x-ray.

Ultrasound is a way of imaging and diagnosing a number of organs and conditions without x-ray radiation. For example, you may have an ultrasound of the abdomen to help determine the health of your liver. Ultrasounds are sometimes used to help doctors further investigate whether cancer has returned.

Bone scan is reserved for people whose cancer shows a possible risk of spreading to the bones or bone pain.

CT scan, also called a CAT scan (computerized axial tomography scan) is like an x-ray but shows images in 3D. This test is very good at showing whether cancer has spread to the liver, lungs, brain or bone. A CT scan can also be used if there is a possibility of cancer recurring.

Positron emission tomography (PET) scan is an imaging test that uses radio-labelled glucose to identify cancer and the recurrence of cancer.

Tumour markers CEA/CA15-3 are tumour markers that can be used to determine the response to your cancer treatment. Your oncologist can decide if this is applicable for your diagnosis.

Magnetic resonance imaging (MRI) is a test that uses magnetic forces and radio frequency waves to make a 3D image of specific areas in your body (i.e., liver). It can be helpful in situations where results from a CT scan are not entirely clear or when a very close look at one area (i.e., the brain) would be helpful. It is also used when other tests suggest a possible recurrence of your cancer.
