Asian Alliance Radiation & Oncology

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.

Patients with HER2-positive breast cancer face a high risk of the cancer spreading to the brain, yet many now live longer and better lives. That makes protecting brain function as important as controlling the disease.

Join Dr Daniel as he discusses CNS risk in HER2-positive disease, today's survival outlook, and approaches that help preserve the brain.

At 29, junior doctor Dr Wang Liting 👩‍⚕️ was diagnosed with breast cancer after getting a second opinion. She had no family history and no obvious risk factors. 💔

She understood the medicine 📚, but her books couldn't teach her how to feel. Through surgery, radiation therapy and setbacks, she found support in her radiation oncologist, Dr Michelle 💗, and Team AARO, who treated her as a person, not just another cancer case. 🤝

Her message to other women 🌸: lean on people, don't compare journeys, and remember that getting through an appointment is a victory too. 🏅

Dr Jonathan Teh Yi Hui, Senior Consultant Radiation Oncologist and Medical Director of the Centre for Stereotactic Radiosurgery (CSR), joined our long-standing partners OncoCare Cancer Centre on their recent regional cancer education outreach symposium.

Dr Teh shared his expertise on the evolution of radiotherapy, from conventional techniques to today's advanced, precision-guided treatments, with patients, caregivers and the public, including in a feature interview on 𝗞𝗼𝗺𝗽𝗮𝘀 𝗧𝗩'𝘀 "𝗕𝗶𝗻𝗰𝗮𝗻𝗴 𝗞𝗶𝘁𝗮".

“Using the right tool for the right situation, based on evidence and experience, allows radiation oncologists to give hope to advanced cancer patients by eliminating their cancers while preserving their quality of life," he said.

As trusted collaborators for more than a decade, AARO has been providing in-house radiation oncology support to OncoCare Cancer Centre, and this trip reflects that continued partnership in bringing quality, personalised cancer care to patients across the region.

📰 We are glad that this visit led to meaningful conversations around early detection and personalised treatment planning

Time to retire that mindset. Advanced cancer care today isn't one-dimensional or passive — it's personalized, coordinated, and built around what matters most to each patient.

Join Dr David Tan as he unpacks how modern oncology combines systemic therapy, local treatment, and active supportive care around clearly-defined patient priorities — because survival isn't the only victory that counts.

🔑 Multidisciplinary. Active. Patient-centered.
