Harnessing Technology | Enabling Hope

Asian Alliance Radiation & Oncology (AARO) is a Singapore Oncology Specialist Group focusing on targeted and non-invasive technologies for cancer treatment.

AARO established Singapore’s first independent Radiotherapy Practice in 2015, led by highly-trained and experienced radiation oncologists from the National Cancer Center Singapore, who also developed the first Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT) programs in Spine, Prostate, and Liver cancers in South-East Asia. 

AARO also provides general oncology services focusing on wellness, prevention, cancer survivorship and specialised programs to manage cancer treatment side effects.

Today, with a multidisciplinary team of oncologists and healthcare professionals from various Cancer Centers in Singapore who are well-versed in the latest cancer treatments and trends, AARO is able to provide best practices and care for our patients. 

Our growing Alliance of cancer specialists provides one-stop personalized solutions for every patient’s unique situation.
