Breast imaging used by Tidelands Health approved by FDA as superior for women with dense breasts

A type of breast imaging used by Tidelands Health has been approved by the FDA as the only mammography exam superior to standard 2D mammography for routine cancer screenings of women with dense breasts.

Nearly half of women ages 40 to 74 have dense breasts, characterized by high proportions of fibrous or glandular tissue and relatively little fat. High breast density can make it harder for radiologists to identify breast cancer using 2D mammography and other imaging techniques, potentially requiring additional scans, greater anxiety and cost to patients.

Hologic’s Genius 3D Mammography exam, offered at all Tidelands Health mammography locations, has earned FDA approval to be labeled as a superior People holding handsalternative to 2D mammography for routine breast cancer screening of women with dense breasts. The expanded labeling was based on clinical studies showing the exam improves invasive breast cancer detection while reducing unnecessary screenings among women of all breast densities, including those with dense breasts, according to Hologic.

The Genius 3D exam is the only mammogram clinically proven to detect 20 to 65 percent more invasive breast cancers compared to 2D alone, with an average increase of 41 percent, according to Hologic.

“Not all imaging equipment is the same,” said Amanda Daugherty, director of imaging services at Tidelands Health. “We encourage patients, including women seeking mammography exams, to understand the differences in technology when making a choice about where to receive care.”

Daugherty said having dense breasts is normal and common among women, but cannot be determined based on a self-exam or a physical exam conducted by a physician. Mammography is the most common approach to determining breast density, she said.

“Patients should develop an individualized screening plan in concert with a qualified health care provider,” said Timothy Laugh, director of cancer services at Tidelands Health. “Early detection of cancer can make a critical difference in treatment outcomes.”

Tidelands Health has offered Hologic’s Genius 3D exam since 2013.
