What is Breast Screening?
In most of the medical cases relating to breast cancer, there are three methods named Breast MRI, Mammography and Ultrasound used to detect breast cancer in women. We’ll be discussing these in details.
Breast MRI (Magnetic Resonance Imaging):
Breast MRI is considered to be one of the most tactful ways of breast cancer detection. It looks along the dye flows inside and out of breasts in addition to the architecture of breasts. Breast MRI is usually used in women who have been detected of breast cancer, to ascertain the size of the tumor and to look up for others tumors in breast along with checking tumors in opposite breasts. However, to the women, a higher risk of breast cancer (having 20% or above chances of developing breast cancer or with BRCA1, BRCA2 gene) MRI screening is recommended followed up by yearly mammogram. MRI itself is not recommended as a screening test because it can miss some tumors that mammogram will detect. The accuracy of Breast MRI can be affected by the hormonal change in women body. So if you are women having a menstrual cycle, it is stressed that you schedule your appointment at the appropriate time during your cycle. Be assured to ask your physician for determining the right time for your breast examination.
Discovered in 1990’s, mammography technique is still considered to be a “gold standard” in the detection of breast cancer. Using the very small amount of X-rays breast is exposed to ionization radiations producing an image of breast tissues which can lead to the discovery of many breast cancer before the appearance of symptoms. The list involves breast pain, skin change associated with breast cancer, mass, abnormal nipple discharge, etc. A mammogram can show calcinations (tiny calcium clusters) or called microcalcifications; Mammogram is further divided into 2-D and 3-D mammography (Digital Tomosynthesis). A mammogram is yet the best technique available for early breast cancer detection.
Using the medical ultrasonography, breast ultrasound uses sound waves for determining the difference in density of breast tissues. It is corresponding to mammography as sometimes it detects the tumors not displayed during mammography screening. Usually, ultrasound suggests that mass that felt or nodule screened on a mammogram is either a solid growth or a fluid-filled cyst. Ultrasound shows the circulation of blood in vessels and breast tissues. Many physicians use the ultrasound technique in physical observation of breasts and axilla (area beneath the arm). The Ultrasound is safe, noninvasive and with no side-effects, as it does not uses ionizing radiations.
