MBBS (Singapore)FRCR (UK)FAMS

Background

Dr Teh graduated from the National University of Singapore in 2002, earning multiple Dean’s List and Book Prize awards, and began his radiation oncology training at the National Cancer Centre Singapore in 2006. In 2009 he received the Health Manpower Development Programme (HMDP) Award for advanced training in Clinical Oncology in the UK, working as an Honorary Clinical Fellow at University College Hospital London and serving with the London Sarcoma Service — one of the largest sarcoma groups in Europe. He obtained his FRCR in 2011 and practised as a Consultant Radiation Oncologist at NCCS from 2011 to 2017.

He was principal investigator of Southeast Asia’s first phase II trial of stereotactic body radiotherapy for prostate cancer, and is first co-author of the publication documenting the efficacy and safety of prostate SBRT in the Singapore population. Credentialed in proton therapy through proctorship at the New York Proton Center and Apollo Proton Cancer Centre, he coordinates the care of AARO patients who would benefit from proton therapy with regional centres — and has personally accompanied patients overseas to provide close clinical support.

Approach to patients

Kind, patient, unhurried.

Dr Teh’s consultations are unhurried and considered. He takes the time to understand each person’s condition and personal needs: what matters to them, what they’re afraid of, and what they need to hear in plain terms.

You won’t be rushed through your appointment, or talked at in jargon. Armed with his technical expertise and the latest scientific evidence, Dr Teh offers a customised treatment plan based on your individual condition — explained by the same person who walks you through it.

For complex cases, Dr Teh convenes a multidisciplinary review with your surgeon and medical oncologist before recommending a path. The decision is collaborative — but it is always yours.

When to consult Dr Teh

You may benefit most if you have:

These are the situations Dr Teh most commonly sees — but every case is different. If you’re unsure whether radiation oncology fits your situation, our care team can help you decide.

Prostate, kidney or bladder cancer

Genitourinary cancers are Dr Teh’s core sub-specialty. He led Southeast Asia’s first prostate SBRT trial and offers precision-radiation options across GU cancers.

Head & neck or GI cancer

Nasopharynx, oral and throat cancers, and upper GI, hepatobiliary and colorectal cancers — treated with modern techniques that protect function and quality of life.

A second opinion

Already under another oncologist’s care and want to confirm whether radiation is the right next step — or hear an experienced view on your treatment plan.

Sarcoma or a paediatric cancer

Dr Teh trained with the London Sarcoma Service and sub-specialises in paediatric cancers — rare situations that call for specific radiation expertise.

Proton therapy assessment

Wondering whether protons offer a real advantage for your case. Dr Teh is proton-credentialed and coordinates referrals and treatment with regional proton centres.

Non-surgical alternatives

You’ve been told surgery carries high risk, or you’d prefer to avoid it. Modern radiation can match surgical outcomes for many cancers — without the recovery time.
