Mammography is a low dose x-ray that provides an image of the internal structure of the breast. It is a screening method for detecting (in patients with no symptoms) and diagnosing breast cancer (in those with symptoms).
Mammography can be used to detect and monitor various masses. Having access to previous mammograms is especially helpful when comparing results. It is therefore recommended that you continue to consult the same radiology facility.
During a mammography, the patient is asked to stand, while undressed from the waist up. The breast is gently placed on a platform and compressed between two plates. Two images are taken - one at 45 degrees, the other laterally. Each breast is compressed for 10 to 15 seconds and the entire process lasts about 15 minutes. Compressing the breasts is necessary as it ensures detailed images that are of good quality. It also serves to separate superimposed structures, limit movement of the breast and ensures the use of the smallest amount of radiation possible.
Breast cancer is one of the leading causes of cancer-related deaths among Canadian women. The risk of developing this type of cancer increases with age. When detected early, one has access to more treatment options, not to mention greater chances for successful recovery. That being said, mammography is an important tool for early detection.
Complementary to breast self-exams, mammography can detect lumps that are too small to detect with a physical exam alone. In Quebec, the Breast Cancer Screening Program recommends that women over the age of 50 have mammographies every two years. Physicians may recommend that women with a personal or family history of breast cancer begin screening at an earlier age, in addition to having a mammography every year. A mammography is highly recommended if you experience any pain or feel a lump in either breast.
When looking at the results, the physician may notice a cyst, abscess, nipple inflammation, benign or malignant lump or benign or malignant microcalcification. However, nine times out of ten, results are normal. One time out of ten, additional imaging is performed.
Breast implants and prior breast surgery can interfere with the interpretation of mammograms. There is no risk of rupturing breast implants during a mammography.
