Breast Self Examination or BSE Breast self-examination is a bit of a controversial topic within the medical community. It is unclear whether self-examination actually results in a reduction in mortality rates. Indeed, reducing mortality rates from breast cancer is the overriding objective of all screening programs. Of course, there is no physical harm in breast […]
Advantages of Ultrasound in Breast Cancer Screening
The benefits of Ultrasound for Breast Cancer Screening The usual indication for an ultrasound for breast cancer would be a suspicious finding. By the way, ultrasound is also sometimes known as ‘sonography’. Specialists may discover a suspicious finding on mammogram or as a palpable lesion (or lump) in a clinical breast exam. Often an ultrasound […]
The use of MRI for Breast Cancer
Typical uses of MRI for breast cancer screening and diagnosis The use of MRI for breast cancer screening, while no longer controversial, remains a balancing act and judgement call for the attending physicians. There is no doubt that the MR image yields greater sensitivity, but the cost is high, and most often a suspicious […]
MRI for Breast Cancer Diagnosis
Use of Magnetic Resonance Imaging MRI for breast cancer Diagnosis and Screening The use of Magnetic Resonance Imaging (or MRI) is not common with initial breast cancer screening. A carefully performed mammogram is much more convenient and economical, and is usually adequate to inform initial decisions as to whether a biopsy is warranted. Mammograms […]
So her name is Gail…
Breast Cancer Risk Calculations: The Gail Model The Gail Model is a statistical breast cancer risk assessment algorithm which was developed by Dr. Mitchell Gail and his colleagues with the Biostatistics Branch of NCI’s Division of Cancer Epidemiology and Genetics. It was developed following a huge screening study of 280 000 women between 35 and […]
Detecting magnets… This is a long one
MRI contrast enhancement Breast Cancer revealed on MRI through dynamic contrast ‘enhancement’ (DCE MRI) For practical reasons, mammography is usually used in breast cancer detection, followed by ultrasound if there are suspected ‘cystic‘ features to a lesion. Magnetic resonance imaging (MRI) is used in breast cancer screening in certain instances, and can sometimes reveal lesions […]

MRI Scan for Detecting Breast Cancer
Magnetic Resonance Imaging (MRI) and malignancy detection The MRI scan is very sensitive for detecting invasive carcinoma. In fact, it is usually very close to 100%. For Ductal Carcinoma In-Situ (DCIS) , the MRI scan sensitivity range is 40% to 100%. This holds true even when the breast lesion is not detectable using other imaging methods such […]
Architectural distortion in breast mammograms
Architectural distortion found on a mammogram Architectural distortion is a somewhat vague phrase used by radiologists, when the mammogram shows a region where the breasts normal appearance, looks like an abnormal arrangement of tissue strands, often a radial or perhaps a somewhat random pattern, but without any associated mass as the apparent cause of this […]
Magnets in situ
Issues surrounding the detection of DCIS using MRI, and typical contrast enhancement patterns The use of MRI in breast cancer screening is still somewhat controversial. MRI often reveals abnormalities with greater sensitivity than mammography, but the lack of specificity of the results more often than not leads to a biopsy anyways. The main goal of […]
