Improved cancer detection in women with dense breast tissue.
A radiologist checks for signs of cancer. On this mammogram, a breast cancer appears as a white mass in a background of normal fatty tissue, which appears black.
40% of women have dense breast tissue that may obscure breast cancers on mammograms. Fibroglandular tissue, or dense breast tissue, also appears white on a mammogram and thus can obscure detection of breast cancers.
MBI is a new breast imaging technique that uses gamma cameras to find cancers missed by mammography in dense breasts. MBI is offered in addition to mammography.
In a Mayo Clinic study, from a sample size of over 2,500 women with dense breast tissue:
32 women were diagnosed with breast cancer.
21 were detected by MBI only
5 were detected by both mammograms and MBI
3 were detected by mammogram only
3 were missed by both mammograms and MBI
When MBI was added to mammography, an additional 21 women had breast cancer detected, for a total of 32 women diagnosed with breast cancer.
