Abstract
BCT is increasingly being integrated into the management of breast cancer. Women who are treated with BCT remain at an increased risk of second breast cancer, either a local recurrence or a new primary in the conserved or contralateral breast. Imaging the treated breast presents challenges because of its limited compressibility and overlapping features of benign post-treatment alterations and tumor recurrence. Our study was conducted at radiology department of Mansoura University Hospitals during the period of December 2017 till March 2019. Patients were referred from Mansoura University Hospitals, Oncology Center of Mansoura University and Outpatient Surgery Clinic based on follow up known cases of histopathologically proven breast cancer who underwent conservation surgery (after minimum 3-6 months post-operative). The reported diagnosis was confirmed by histopathology of specimens obtained by excision biopsy or core biopsy. The study included 40 women patients with 79 suspected breast lesions and the age of patients ranging from 30-70 years with mean age 50.7 years. All the patients were evaluated with Mammogram, US, DCE MRI and DWI. The most common indication was follow-up in 77.2% followed by palpable lesion in 17.7%. And the UOQ was the most common affected site followed by the UIQ. 87% of the lesions were related to the surgical bed, 89.2% were benign lesions and 75% malignant lesions while 13% of the lesions were away from the surgical bed, 10.8% were benign lesions and 25% malignant lesions.
