The Breast Gamma Camera lightly compresses your breast between two camera heads, while you are injected with a small dose of radioactive material. The material, sestamibi, travels to the tumor and makes it more visible to the gamma cameras. Like a breast MRI, several views are taken during the imaging, and even dense breast tissue can be clearly imaged. Even tumors that are smaller than 10 millimeters can be found using this new method. Such a small tumor can be removed with a lumpectomy and then treated with local radiation. Recovery is much faster than it would be if the tumor was larger and required external beam radiation. This new imaging device is still being compared to standard mammography, to find out which method is more accurate.
