The Gail model significantly underestimates the risk of breast cancer in women with atypia. Its ability to discriminate women with atypia into those who did and did not develop breast cancer is limited. Health care professionals should be cautious when using the Gail model to counsel individual patients with atypia

Previous axillary dissection or irradiation to the breast greatly influences lymphatic flow. Irradiation to the breast may be a strong factor for the visualization of contralateral axillary nodes. Despite the frequent alteration of lymphatic flow, SNB seems to be feasible in secondary or recurrent breast cancer patients.

Adding a single screening ultrasound to mammography will yield an additional 1.1 to 7.2 cancers per 1000 high-risk women, but it will also substantially increase the number of false positives.

Results of the ACRIN 6666 trial, whose results were presented at RSNA 2007. As expected ultrasound is good at picking up additional cancers, not visualized on mammography, BUT at a significant cost of false positivies and unnecessary biopsies.

An interesting paper from Cambridge. The authors suggest that tumours picked up at screening are biologically different enough that current methods for estimating prognosis and therefore treatment, overestimate the benefit of systemic treatments in screen-detected cancers and lead to overtreatment of these patients.

By preoperative US and FNA of the axilla in patients with breast cancer, half of the axillary metastases can be detected prior to surgery. In more than a quarter of breast cancer patients, a futile SNP can be prevented.

Therefore, preoperative US of the axilla plus FNA are obligatory in patients with breast carcinoma.
