A doctor called a radiologist will categorize your mammogram results using a number system of 0 through 6. You should talk to your doctor about your mammogram's category and what you need to do next. Doctors use a standard system to describe mammogram findings and results.
Category 4 is not subdivided for breast MRI because of a paucity of data. All screening breast MRI examinations performed from July 1,through June 30,were included in this study. Benign versus malignant outcomes were determined by pathologic analysis, findings from 12 months or more clinical or imaging follow-up, or a combination of these methods.
Each BI- RADS category has a follow-up recommendation associated with it to help radiologists and other physicians appropriately manage a patient's care. The categories are:. Your report will also describe the composition of your breast tissue. This is divided into four categories related to breast density:.
BI-RADS is a scheme for putting the findings from mammogram screening for breast cancer diagnosis into a small number of well-defined categories. The benefit of BI-RADS to radiologists is that it forces them to think about which category their findings will fit into and when they assign each case a category it then becomes possible to calculate accuracy statistics. The accuracy statistics are generally calculated once a year and they are important in quality assurance, that is they tell the radiologist whether they are doing a good job or not.
When a radiologist interprets a mammogramhe or she assigns a score to it used to communicate with doctors about how concerned he or she is about the findings. Did anything look abnormal? How serious is the abnormality that was found?
The nurse explained that there are 5 [categories], but I neglected to ask what being a category 4 means. Does it mean that it's likely that I have cancer and they just need to confirm it, or are they just testing for it? The system allows the radiologist to review the mammogram films and to give them a rating, which is easily understood by the referring doctor.
BI-RADS 4 lesions may not have the characteristic morphology of breast cancer but have a definite probability of being malignant. A biopsy is recommended for these lesions. If possible, the relevant probabilities should be cited so that the patient and her physician can decide on the ultimate course of action.
A mammogram is an X-ray imaging test that examines breast health. It can also be used as a follow-up tool when doctors find abnormal masses during a clinical breast exam. Not all abnormal findings are considered cancerous.
