Onco Surgery Department – Introduction

The Onco Surgery Department is a specialized unit dedicated to the surgical management of benign and malignant tumors across various organ systems. The department provides comprehensive, evidence-based surgical care as an integral part of multidisciplinary cancer treatment.

Our services include early cancer detection, diagnostic biopsies, curative and palliative oncologic surgeries, minimally invasive and organ-preserving procedures, and complex reconstructions. The department manages cancers of the breast, gastrointestinal tract, head and neck, thorax, gynecologic organs, urology, and soft tissues.

The department is staffed by highly trained surgical oncologists, anesthesiologists, oncology nurses, and allied healthcare professionals who work collaboratively with medical oncology, radiation oncology, pathology, radiology, and rehabilitation teams to ensure seamless and personalized patient care.

With a strong emphasis on surgical precision, patient safety, and postoperative recovery, the Onco Surgery Department is committed to delivering high-quality outcomes while maintaining compassion, dignity, and support throughout the patient’s cancer journey.
