Breast cancer was found every year when a mammography test was performed and had been diagnosed with no abnormality. This was because she was a Densblest and could not find any abnormalities. 40%of American women at the time were Densblest, and the mammography has a low detection sensitivity for Denzbrest, and there is a way to use it in combination with ultrasound and MRI tests.
If you have a breast cancer screening, make sure you are Denzbrest. If it is a Densblest, you should also have a mammography test and ultrasonography.
Even if you are diagnosed with no abnormality in a mammography test, you will need an ultrasonography because you may have breast cancer in the case of Densblest.
