How Does Mammography Work?
Mammography is a specialized medical imaging technique used to examine breast tissue for early detection of breast cancer and other abnormalities. It involves the use of low-dose X-rays to create detailed images of the breasts.
Procedure
The mammography procedure typically takes about 15 to 30 minutes, and it is performed by a trained technician. During the exam:
- Positioning: The patient is positioned in front of the mammography machine.
- Compression: Each breast is placed on a flat plate and compressed with another plate to obtain clear images.
- X-ray Imaging: Two standard views are usually taken of each breast, capturing multiple angles for thorough evaluation.
Types of Mammography
There are two main types of mammography:
- Screening Mammography: This is performed on women who have no symptoms, usually annually or biennially.
- Diagnostic Mammography: This is conducted when there are abnormal findings or symptoms, such as a lump or unusual breast changes.
Benefits
Mammography is crucial for early detection, significantly improving the chances of successful treatment. Regular screenings are recommended for women starting at age 40 or earlier, based on risk factors, to ensure timely diagnosis and intervention.
