Aims and objectives
Early identification of Breast Cancer (BC) through mammography screening programs of general population is amply demonstrated in several studies conducted over the past years,
that report a reduction in mortality of about 22% for women aged 50-69 years old [1,5].
Actually Mammography (MMG),
although not perfect,
can be considered the main screening test in order to detected early BC with a sensitivity of 75%-85% calculated in general population [2],
up to 80%-98% in women with fat breast tissue (ACR D1-D2) [3].

Methods and materials
At the Center of Breast and Ovarian Familiar Tumors in Modena,
3306 women considered at increased familiar risk for BC were enrolled in a surveillance program from January 1994 to June 2014 and divided into four risk categories depending on familiar history or BRCA status according to Modena Criteria: BRCA mutation carriers (BRCA+),
High,
Intermediated andSlightlyincreasedrisk (Fig.1).
Clinical Breast Examination (CBE),
MMG,
US and MR are performed annually by experts radiologists of about 10-20 years of breast imaging experience at our dedicated clinic located at...
Results
After a median follow up of about 11 years,
150 cancers were diagnosed on 148 patients,
of these 134/150 (89%) were Screen Detected Breast Cancers (SDBC),
while 16/150 (11%) were Interval Breast Cancer (IBC).
Of 134 SDBC 32 (24%) were detected by US alone,
95 (71%) by MMG alone or plus US,
7 (5%) by MR (Fig.3-4); 60,4% in High risk group and 17,2% in BRCA+ group; patients ages ranged from 32 to 87 years; 43% below age 50 years,
while 57% aged ≥50.

Conclusion
MMG is a recommended imaging modality for detection of BC in general population,
although with a sensitivity that progressively and greatly decreases in a proportional way according to the increment of breast density [10] with low performance for young women where the added value of MMG is very low [12].
In women aged 30-39 years who manifest clinical symptoms,
breast US should be the primary imaging approach,
while MMG represents the first modality in the older group [12].
In high risk population MMG alone is...
