MRCCC Siloam Hospitals Semanggi is the flagship cancer hospital of the Siloam group, on Jl. Garnisun Dalam in Karet Semanggi, just off the Semanggi interchange on Jalan Sudirman. It opened in 2011 and describes itself as Indonesia's first and largest private comprehensive cancer centre. For expats living or working around Sudirman, Kuningan and SCBD it is a central, easy-to-reach option for cancer screening and treatment.

The hospital takes a multidisciplinary approach that brings medical oncology, surgical oncology, radiology, pathology and nuclear medicine together. Services run from early detection and diagnosis through chemotherapy, radiotherapy and brachytherapy, PET and SPECT imaging, Lu-PSMA therapy, thyroid ablation and haematopoietic stem cell transplantation, alongside palliative and home care. In January 2026 it introduced what Siloam calls Southeast Asia's first integrated CT linac for precision radiotherapy.

MRCCC holds Joint Commission International (JCI) accreditation and has more than 200 inpatient beds and over 170 specialist doctors. As with any planned treatment, confirm a guarantee of payment with your own insurer before admission, as direct-billing terms differ by policy.
