How Does Ultrasonography Play A Role In The Evaluation of Breast Cancer? In the evaluation of breast cancer, the use of ultrasonography is gaining greater prominence in the world. Also known as ultra sound scanning or ultrasound imaging, ultrasonography is an advanced way to capture images of the insides of the body. This is done by using high-frequency sound waves on an exposed part of the body. Unlike x-rays, ionizing radiation is not used in ultrasonography. Ultrasound scanning is extremely useful for showing the movement and structure of the internal organs if the body and even the flowing of blood through the blood vessels. All these images are possible because ultrasonography uses real-time technology. How does ultrasound imaging play a role in the evaluation of breast cancer? Let’s take a look. When there’s a need to get an image of the breast’s internal structures, ultrasound scanning is the best solution. In a breast ultrasound examination, there may be a need to assess the consistency of blood flow in the breast mass. To do this, the sonographer may perform a Doppler ultrasound to learn more about how the breast mass is caused. Doppler ultrasound makes it possible for physicians and sonographers to assess the blood flow in a blood vessel as well as the major veins and arteries in the body. When a breast abnormality is found, the doctor will recommend ultrasonograpy to diagnose the nature of the abnormality. It may come in the form of spontaneous clear or bloody nipple discharge or a lump. Potential abnormalities in the breast may also be observed in breast magnetic resonance imaging or mammography. It’s then important to find out if the abnormality is fluid-filled, solid or fluidfilled and solid, which is done by ultrasound imaging. If the abnormality is fluid-filled, it can be a benign cyst but the abnormality can be a cancerous tumor or a lump of tissue which is non-cancerous if it is found to be solid. To examine the blood supply of breast lesions, sonographers will perform Doppler ultrasound. At this time, the only breast cancer screening tool to have reduced breast cancer deaths by early detection is mammography. However, it must be noted that not all types of breast cancers are detectable by mammograms. For instance, many types of cancers in dense breasts are difficult to be seen on mammography because these breasts have a lot of fibrous tissue, glands, ducts but not so much fat. In these circumstances, magnetic resonance imaging (MRI) or ultrasound scanning may be used to supplement mammography, and spot the small breast cancers. Ultrasound scanning may not be as good as MRI for the depiction of breast cancer but it’s an alternative for women who cannot use MRI. An ultrasound-guided biopsy may be ordered by a physician when a suspicious breast abnormality is shown by an ultrasound scanning. Ultrasound is suitable for guided biopsy because it’s capable of producing real-time images. To find out if this form of biopsy can be used and to plan the procedure, the physician will have to perform an ultrasound examination first.
