“…Besides, there were statistically differences of calcification performance rate between different age groups. Proved by pathology, microcalcifications revealed by mammography in young patients were more frequently a manifestation of DCIS (Hermann et al, 1988;Papatestas et al, 1990;Evans et al, 1997). Even invasive malignancies presenting as calcifications also associated with extensive intraductal carcinoma (Healey et al, 1989;Schmidt-Ullrich et al, 1993).…”

Objective: To compare the mammogarphic appearance between breast cancer patients aged <40 and ≥40 years. Methods: Needle localization and biopsy of suspicious mammographic lesions identified 1,959 breast carcinomas in a single institution from Jun 2012 to Apr 2013. According to the age, we divided patients into two groups: <40 and ≥40 years old, and analyzed mammographic appearance separately. Results: Young patients had 44.2% foci with calcification, but old patients only had 39.4% (P<0.001). In younger group, the ratios of cases according to mass density were 41.8% or higher, 58.2% equivalent and lower. In older group, the ratios were 55.5 % and 44.5%, respectively. There were statistical differences between high density and others (P<0.05). The ratios of cases according to mass margin were 13.9% circumscribed and microlobulated, 86.1% indistinct and spiculated in the younger group, as compared to 6.5% and 93.5%, respectively, in the older group (P<0.05). Conclusions: Mammographic findings differ between young and old patients with breast cancer, for example regarding mass density, mass margin and microcalcification ratios.

“…Its true incidence in the general population therefore cannot be reliably determined and is probably underestimated [8, 50, 54--56]. The results of 18 series [58][59][60][61][62][63][64][65][66][67][68][69] that reported 6609 nonpalpable breast biopsies (Table 2) show LCIS to comprise 2.2% (143 of 6609) of all biopsy specimens and 9.8% (143 of 1455) of all breast malignancies [31].

In situ breast carcinoma represents an early localized stage in the transition to invasive breast carcinoma and has an especially favorable prognosis with appropriate management. The widespread use of mammography has contributed to its increased rate of diagnosis. The two histologic forms of this entity have distinct pathologic and biologic characteristics, with different therapeutic implications. Lobular carcinoma in situ is considered a marker of increased risk for subsequent invasive carcinoma and is most commonly managed by nonoperative surveillance. Ductal carcinoma in situ behaves more as a true anatomic precursor of invasive disease and has the same therapeutic options as invasive breast carcinoma. Minimally invasive breast carcinoma should be considered a fundamentally different entity, primarily because of its potential for systemic metastasis that in situ lesions do not theoretically have. There are still many outstanding issues and dilemmas to be resolved by scientific investigation before the intriguing potential of these early forms of breast malignancy are fully understood.

“…Approximately 15–20% of such lesions are proved to be malignant and require surgical removal following radioguided localization of the lesion [2]. Modern imaging allows us to identify potentially malignant breast lesions even before they become palpable.…”

Purpose. For accurate resection of nonpalpable malignant breast lesions with a tumor-free resection rim, an exact and stable wire localization is essential. We tested the resistance towards traction force of different localization devices used in our clinic for breast lesions in two types of tissue. Materials and Methods. Eight different commercially available hook-wire devices were examined for resistance towards traction force using an analogue spring scale. Results. Most systems showed a high level of movement already under small traction force. Retractable systems with round hooks such as the Bard DuaLok , the Fil d'Ariane, and the RPLN Breast Localization Device withstood less traction force than the other systems. However, the Bard DuaLok system was very resistant towards a small traction force of 50 g when compared to the other systems. The Ultrawire Breast Localization Device withstood the most traction force in softer tissue and Kopans Breast Lesion Localization Needle withstood the most force in harder tissue. Conclusion. The Ultrawire Breast Localization Device and Kopans Breast Lesion Localization Needle withstood the most traction force. In general retractable systems withstand less traction force than nonretractable systems.
