Memorial Sisli Hospital provides Lumpectomy using contemporary breast-conserving surgery techniques and evidence-based oncology care. Founded in 2000, the JCI, NABH accredited hospital is based in Istanbul, Turkey, with 252 beds and services for domestic and international patients.

During the procedure, the surgeon removes the tumour and a surrounding margin of tissue while preserving the remaining breast. Lumpectomy may be combined with lymph-node assessment when clinically indicated. Before treatment, specialists evaluate tumour characteristics, imaging, pathology, and overall health to determine whether breast-conserving surgery is appropriate.
