Breast lesions can be found via ultrasound imaging, which is also utilized to determine where the worrisome lesion is located. High-frequency sound waves are sent into the breast tissues by the ultrasound transducer, which then picks up reflected sound waves. 2D graphics are shown using these waves that were discovered. Real-time photos may be taken continuously while the sensor is moved over the breast. In addition to mammography, ultrasound can be utilized in clinical examinations to evaluate breast abnormalities that are both palpable and impalpable. Unacceptable false positive and false negative results are produced by ultrasound screening in asymptomatic women. As a result, the use of breast ultrasonography in breast cancer screening is not well supported by the available research.
Breast Cancer in mammography:-
Many malignancies are missed by mammography alone in women with thick breasts. For women with thick breasts and/or at increased risk of breast cancer, the diagnostic yield of mammography with an automated whole breast ultrasound (AWBU) is superior. According to a research by Kelly et al., 68 percent of investigations including women with thick/very dense breasts revealed 87 percent of the cancer detections added by AWBU. As a consequence, AWBU significantly improved cancer diagnosis when compared to mammography alone. Sonography should always be used in conjunction with mammography or other imaging modalities, according to Kopans. It cannot correctly identify lesions on its own. The ACRIN 6666 experiment is a different investigation that supports the use of mammography and ultrasonography in tandem. The study’s findings suggested that adding a screening ultrasound to mammography might find an extra 1.1 to 7.2 malignancies per 1000 high-risk women, albeit at the cost of a higher rate of false positives. Japanese women in their late 40s with small, thick breasts frequently get breast cancer. It was demonstrated that ultrasonography performed similarly to mammography in identifying breast malignancies in these patients.
MANY MODALITIES ARE USED TO DETECT BREAST CANCER
Review of the different breast cancer detection techniques is provided in this section:-
Mammography:-
The most used technique for breast imaging is mammography. To inspect the human breast, low-dose, high-amplitude X-rays are used. On the mammography, calcium deposits and cancerous tumours are more visible. This technique is effective for finding calcifications and ductal carcinoma in situ (DCIS). Mammography is now the best way to find breast cancer in its early stages before the lesions become clinically palpable. In screened women, mammography has contributed to a 25–30% death rate reduction when compared to a control group after 5–7 years.
Mammographic screening cannot reliably identify cancer in its early stages. Additional screenings, however, could lower the mortality rate from breast cancer. In randomised controlled studies with the general population, the mammography screening test has been found to reduce the mortality rate.
The standard mammography technique has been changed in digital tomosynthesis mammography in order to get 3D pictures of the breast. Contrast compounds are employed in ductography, another form, to detect the presence of a mass inside the ducts. Contrast-enhanced digital mammography (CEDM), a new advancement in mammography, employs an intravenous injection of an iodinated contrast agent in tandem with a mammography examination.
Infrared breast imaging:-
Because precancerous and cancerous tissues have a greater metabolic rate, new blood vessels are able to form and feed nourishment to the rapidly expanding cancer cells. As a result, compared to the temperature of normal breast tissue, the region around precancerous and cancerous breast tissue is warmer. It has been established that the breast has a circadian rhythm that corresponds to physiology. There is evidence to suggest that these rhythms, linked to the growth of malignant cells, are not circadian. Breast skin temperature and breast cancer have been studied in connection to one another. Skin temperatures between clinically healthy and malignant breasts showed measurable variations. In a controlled context, the cyclic temperature change and vascularization of normal breast thermograms were investigated. The analysis of both normal and pathological breast thermography is aided by the study’s findings.
Breast thermograms are now often employed for the timely identification of breast cancer. Because thermography may detect breast cancer at least 10 years in advance, it is a potential screening method. Analysts are, nevertheless, necessary for thermogram analysis and interpretation.
MRI:-
Due to its abundance in water and fat, the hydrogen nucleus (a single proton) is used in MRI imaging. Any area of the body may provide precise photographs thanks to the hydrogen nucleus’ magnetic characteristic. A magnetic field is applied to the subject of an MRI examination, and a radio frequency wave is then used to produce high contrast pictures of the breast. Before the pictures are taken, a contrast agent is injected in dynamic contrast enhanced-MRI (DCE-MRI). It has been discovered that this method is more sensitive than mammography.
