Breast cancer is one of the leading causes of death in women, and early detection can greatly improve the chances of survival. Mammography and ultrasound are two of the most common techniques used to diagnose breast cancer. While both are valuable diagnostic tools, there are some distinct differences between the two.
Mammography is an X-ray imaging technique used to assess the density of the breast tissue. It is the most common method of breast cancer screening and can detect tumors that are too small to be felt by hand. The X-ray images produced by mammography can reveal abnormal growths or calcifications in the breast tissue, which may indicate the presence of cancer. The accuracy of mammography is highly dependent on the experience of the radiologist interpreting the images.
Ultrasound, on the other hand, is a non-invasive imaging technique that uses sound waves to create images of the inside of the body. It is useful for detecting cysts and other abnormalities in the breast tissue that may be indicative of cancer. Ultrasound can also be used to guide the biopsy of a suspicious lesion, allowing for a more precise diagnosis. Unlike mammography, which relies on the interpretation of a radiologist, ultrasound can be performed by a trained technician.
In terms of accuracy, mammography is the more reliable of the two methods for detecting breast cancer. However, ultrasound can be helpful in detecting lesions that are too small for mammography to detect. Additionally, ultrasound is considered a safer option since it does not use radiation like mammography does.
In some cases, a combination of mammography and ultrasound can provide the best chance of early diagnosis and improved prognosis. In other cases, ultrasound - the safest breast screening device that uses sound waves to make a diagnosis - is a preferred initial screening method, however, patients are currently required to undergo mammography - a radioactive breast screening device that uses x-rays and has the potential to cause cancer - regardless.
Currently, the decision of which technique to use for breast cancer diagnosis is based on the patient’s medical history and the results of other tests. Often, patients don't have the ability to make a choice of diagnostic tests for breast cancer screenings, however, as technologies improve, and the risks and benefits of each are made more prevalent to patients and clinicians, patient preference will be taken into consideration.
