Particularités de l'imagerie des cancers du sein chez les femmes jeunes et mutées

The cancer of the young woman arises before the age of 40 years, it is rare, it is thus important to think of this diagnosis in the exploration of a palpable mass in a young woman. It is the most frequent mode of revelation. These tumors are more often ductal invasive carcinomas, of high grade with embols and discovered to a more advanced stage (T2, N+). The young age is not an independent factor. A BRCA mutation must be looked for; it is found there more frequently. Mammogram and ultrasound features are non specific, but suggestive of a suspicious lesion, but a bigger frequency of pseudobenign-round tumors especially at the BRCA1 patients is noted. Breast MRI is sometimes useful in the assessment of extension; its accuracy is recognized associated with mammography ± ultrasound as method of screening in high-risk women.
