Breast cancer
When I was diagnosed with breast cancer 2 months ago, I met an amazing person who took on all my fears and anxieties. Her smile, attentiveness, experience, and dedication to learning are remarkable. The team works with her day and night. The treatment is not yet completed. Thank you very much.

Turkey, Istanbul

Acıbadem Altunizade Hospital is one of the most technologically advanced private medical centers in Istanbul, part of the Acıbadem Healthcare Group network. The clinic focuses on complex cases and multidisciplinary treatment, where a team of specialists — rather than a single physician — works with each patient.

Strong directions are concentrated here: oncology, neurosurgery, cardiology, transplantology. In cancer treatment, modern protocols are actively used, including targeted therapy and immunotherapy — methods that act on the tumor more precisely and gently for the body.

The operating rooms are equipped with expert-level equipment, including robotic systems, which allows minimally invasive interventions with rapid recovery. Special attention is paid to diagnostics: MRI, PET-CT, and laboratories operate according to international standards.

For patients from abroad, full coordination of treatment is provided: interpreters, accompaniment, hotel-level comfortable rooms. This is a clinic where people come not for “general treatment,” but for a precise medical strategy and outcome.
