What is Mammography?
Mammography is a specialized medical imaging technique that uses low-dose X-rays to create detailed images of the breast tissue. It is used to detect early signs of breast cancer in women who have no symptoms, as well as to evaluate breast lumps and abnormalities detected during a physical examination.
How Does Mammography Work?
During a mammogram, the breast is compressed between two plates and an X-ray is taken. The breast is compressed to spread out the breast tissue, which allows for a clearer image to be taken. The X-ray images are then examined by a radiologist, who looks for any abnormalities or signs of breast cancer.
Mammography is typically recommended for women over the age of 50, or for women with a family history of breast cancer or other risk factors. The procedure is performed in a specialized medical facility, such as a hospital or radiology clinic, by a trained radiologic technologist. The procedure usually takes around 30 minutes and involves the patient standing or sitting while the mammogram is taken.
Benefits of Mammography:
The primary benefit of mammography is the early detection of breast cancer. Detecting breast cancer early greatly improves the chances of successful treatment and recovery. Mammography can detect breast cancer at an early stage, before symptoms are present, which can lead to earlier treatment and a better chance of survival. Mammography can also be used to monitor the effectiveness of breast cancer treatment.
Types of Mammograms:
- Film-Screen Mammography:
Film-screen mammography is the traditional method of mammography, where the X-ray images are captured on film. The images are developed using chemicals, and the film is examined by a radiologist. While film-screen mammography is still used in some areas, it is becoming less common as digital mammography technology becomes more widely available.
- Digital Mammography:
Digital mammography uses digital technology to capture and store X-ray images of the breast tissue. Digital mammography has several advantages over traditional film mammography, including faster image acquisition and processing, better image quality, and the ability to manipulate the images for more accurate readings.
- 3D Digital Mammography:
3D digital mammography, also known as breast tomosynthesis, is a newer technology that creates 3D images of the breast tissue. This technology provides a more detailed view of the breast tissue, making it easier to detect small abnormalities that may be missed with traditional mammography. 3D mammography is more accurate than traditional mammography, particularly for women with dense breast tissue.
Use of Mammography:
Mammography is primarily used for breast cancer screening and diagnosis. However, there are several other uses of mammography, including:
- Breast Cancer Surveillance:
Mammography is used to monitor women who have been diagnosed with breast cancer and are undergoing treatment. It can also be used to detect breast cancer recurrence in women who have previously been treated for breast cancer.
- Breast Cancer Risk Assessment:
Mammography can be used to assess a woman's risk of developing breast cancer. Women who are at high risk of breast cancer may be recommended to undergo more frequent mammography screenings or other preventive measures.
- Evaluation of Breast Abnormalities:
Mammography is used to evaluate breast lumps or abnormalities detected during a physical examination. It can help determine whether the abnormality is cancerous or non-cancerous.
- Biopsy Guidance:
Mammography can be used to guide a biopsy of the breast tissue. This can help obtain a tissue sample for further evaluation and diagnosis.
