Mammography is essential for early cancer detection, yet it poses challenges for women with dense breast tissue, which can obscure tumors. A recent study published in The Lancet compared three imaging techniques and identified that two contrast-enhanced methods outperformed ultrasound when used with mammography for dense breasts. Despite these findings, uncertainty remains regarding effectiveness in reducing cancer mortality and the potential for overdiagnosis. Women with dense breasts are significantly more likely to develop and have undetected breast cancer, highlighting the pressing need for advancements in screening methods.
Experts note that women with high breast density face two distinct risks: they are up to four times more likely to develop breast cancer, and their tumors are more likely to go undetected until later stages.
A pioneering clinical trial...found that two contrast-enhanced techniques were more effective than ultrasound when used alongside mammography. However, the research did not evaluate key clinical outcomes.
