Aims and objectives: Background: Breast Cancer in women under 40 years of age is rare and typically presents symptomatically. The optimal imaging modality for this patient group is controversial. Most women undergo ultrasonography with/without mammography. Young women typically have dense breasts, which can obscure the [...]

Methods and materials: Retrospective review of all women under the age of 40 years managed at our breast cancer unit from January 2009 to December 2015 that presented symptomatically, with histologically confirmed breast cancer. Only women that had a digital mammogram, in addition to ultrasonography, as part of their[...]

Results: Between the 1st of January 2009 to the 31st of December 2015, 13,076 new female patients under 40 years of age attended the symptomatic breast clinic. Of these, 144 patients were subsequently diagnosed with breast cancer and of these, 120 patients had presented symptomatically and underwent mammogra[...]

Conclusion: This study demonstrates the superior sensitivity of ultrasound for breast cancer in women under the age of 40 years, however the results show that digital mammography has an important complimentary role in the comprehensive assessment of these patients, particularly in the diagnosis of DCIS.
