Bengaluru, August 11, 2017: Breast Cancer has been ranked as the number one cancer among Indian women with age adjusted rate as high as 25.8 per 100,000 women, as per the latest statistics published in the Asia Pacific Journal of Clinical Oncology. Bengaluru has ranked third with age adjusted incidence rate of carcinoma of the breast found as high as 34.4 per 100,000 women. Projections for India suggest the number of breast cancer cases will likely go as high as 1,797,900 by 2020. Though there has been an increase in health check-ups among women recently, we can still see that screening is low on priority even in major cities.
Cytecarehospital is the first hospital in the city to introduce Digital BreastTomosynthesis (popularly known as 3D-Mammography) for women.
Mammographycontinues to be the only screening test proven to decrease mortality frombreast cancer. However, 2D mammography is less accurate in women with densebreasts for whom cancer may be masked by overlapping breast tissue. When a 2Dmammogram detects an area of concern, radiologists further investigate with adiagnostic mammogram, ultrasound or biopsy. Looking at the same breast tissuein 3D, the radiologist may now be able to see that the abnormality on 2Dmammogram in fact represents normal breast tissue. This avoids furtherinvestigation in large number of patients undergoing routine screening.
3Dmammography or Tomosynthesis is a special kind of mammogram that uses severallow dose x-rays obtained at different angles to create multiple images or“sequential slices” that step through the breast tissue and allows radiologiststo see more clearly. The breast is positioned and compressed in the same way asfor a 2D mammogram but the x-ray tube moves in a circular arc around thebreast. It takes less than 10 seconds for the scan. The information from thex-rays is sent to a computer, which produces a focused 3-D digital image of thebreast.
Talkingabout Digital Breast Tomosynthesis Dr. Mukta Mahajan, Consultant radiologist,Breast Imaging and Intervention said "The most important aspect as a Breast Radiologist at Cytecare Hospital is to spread awarenessabout personal risk-based screening and extent evaluation of breast cancerprior to planning treatment. There is no organised national or regional breast cancer screening program inIndia. Naturally, majority of those involved in women's health are not aware ofthe available technology and expertise in the field of breast cancer diagnosis.Needless to say, women undergoing screening have little understanding of thetests or the results thereof.
In contrastto the western world, breast cancer incidence is much higher in premenopausalage group (<50 years) in India. As compared to both screen-film and Computed Mammograms (older but most widely used technologies), 2D and 3DDigital Mammography has significantly higher accuracy in cancer detection inyounger women and in women with dense glandular breasts. This willhave large impact on decreasing the number of women undergoing unnecessaryrecalls or biopsies. It is most important to avoid anxiety in women opting forscreening tests. 3D mammography serves as an excellent problem solving tool andreduces misdiagnoses. Contrary to common practice, ultrasound alone hassignificant limitations as a screening tool and must always be combined with a2D or 3D Digital Mammogram. The x-ray dose of 3D mammography is comparable tothat of a 2D mammogram. Therefore the cumulative dose of the combined screeningis still below the FDA-regulated limit and found to be safe and effective forpatient use. I think this technology has greater relevance for Indianwomen.
Incorporatingthis aspect Cytecare hospital's breast imaging services are complete withDigital Breast Tomosynthesis (DBT or 3D Mammogram),Full Field Digital Mammogram (FFDM), Stereotactic andVacuum Assisted Breast Biopsy (VABB). ”
3Dmammography has shown to reduce percentage of missed cancers by 15%. Morerecent studies show about 30% increased 3D mammography sensitivity andspecificity compared to 2D Mammography with a recalls reduction in screening byapproximately 40%.
