Mammogram
Mammogram
A Mammogram (/ˈmaməˌɡram/) is a specific type of breast imaging that uses low-dose x-rays to detect cancer early – before women experience symptoms – when it is most treatable.
Etymology
The term "Mammogram" is derived from the Greek words "mamma" meaning breast and "gramma" meaning something written or drawn.
Procedure
A mammogram is performed using a special x-ray machine designed for breast tissues. The breast is placed on a flat surface and compressed with a paddle to spread the tissue. This allows for a clearer view of the breast. The x-ray machine takes pictures from several angles, which are then examined by a radiologist for any signs of cancer.
Types of Mammograms
There are two types of mammograms: screening mammograms and diagnostic mammograms. Screening mammograms are routine checks when no symptoms are present, while diagnostic mammograms are used after suspicious results on a screening mammogram or after some signs of breast cancer alert the physician to check the tissue.
Risks and Benefits
While mammograms are an effective tool in the early detection of breast cancer, they also carry risks such as false positives, overdiagnosis, and exposure to radiation. However, the benefits of early detection often outweigh these risks.
