A mammogram is an X-ray image of the breast. Mammograms were first developed in the early to mid 1900s; however, they were not widely used for diagnostic purposes until the 1970s. Since then, the technology has greatly improved. More and more women are receiving mammograms each year because mammography screenings are highly proven to reduce breast cancer mortality.
There are two types of mammograms: screening and diagnostic. Screening mammograms are used to detect breast changes in women who do not have any symptoms. Diagnostic mammograms are used to investigate suspicious breast changes such as a new lump. They can be used to follow up on a screening mammogram, and they provide additional images.
DBT (3D Mammography)
Approved about ten years ago, digital breast tomosynthesis (DBT) is the latest advancement in detecting breast cancer early. It has become the standard for breast cancer screening in the United States. DBT takes several images of the breast and combines them to create a 3D image. The images can be examined as a whole or as individual slices. The DBT machine also creates 2D images, which can be used in conjunction with 3D images to reveal abnormalities.
The Impact of DBT
Studies indicate that DBT helps detect more instances of cancer than standard mammograms. This is because it allows doctors to see through possible dense breast tissue. When compared to standard mammography, DBT reduces false positive rates, lessening the number of call-backs by up to 30%. DBT produces around 200 images, whereas a 2D mammogram involves about four images. Tumors are much easier to identify with DBT because the images are taken from many different angles.
How This Applies to You
Mammography is an essential part of detecting breast cancer early. It is recommended that women begin annual mammography screening at the age of 40. If you are at a higher risk for breast cancer, you should consider screening at an earlier age. Women should regularly examine their breasts and report any changes to a healthcare provider.
