| Title | Breast, Ductal Carcinoma in Situ (DCIS) |
| Text | Discussion (include references): Given the increased use of mammographic screening over the past few decades, DCIS is the most rapidly growing subgroup of breast cancer. DCIS was newly diagnosed over 55,000 times in 2003. As a direct precursor to invasive breast cancer, diagnosing DCIS is important to preventing widespread disease. For a patient such as this, where mammography and US showed no abnormalities, but she was still having pain, MRI is a logical next step. Almost all invasive cancers will enhance with gadolinium on MRI (95-100% sensitivity); it is less for DCIS. However, in this patient, there was no enhancement. Also of note, MRI can be helpful in determining the extent of disease spread posteriorly (chest wall, muscle, etc.) However, the routine use of breast MRI is being studied and compared with that of mammagraphy. MRI is often much more expensive, less available, and may have a higher false positive rate for enhancing benign lesions. |
