Radiotherapy, also known as radiation therapy in Singapore, is an effective treatment for cancer patients. It is a treatment modality where a radiation oncologist utilises high energy X-rays or radioactive implants to kill cancer cells. External-beam radiation therapy frequently utilises X-rays to treat cancers, but protons and other types of energy beams are also utilised. An effective option across various stages of cancer treatment, radiotherapy is an essential treatment tool administered by radiation oncologists in Singapore. Dr Johann Tang’s extensive experience in treating a wide variety of cancers reassures patients that they will receive the most appropriate and personalised treatment.

Dr Tang obtained his medical degree from the University of Newcastle, Australia in 1998, and completed his house officer training at the Hunter Area Health Service in Australia. After his successful training, Dr Tang returned to Singapore to start his speciality training in Radiation Oncology at the National University Hospital (NUH). Obtaining his fellowship from the Royal Australian College of Radiologist (FRANZCR) in 2006, Dr Tang underwent fellowships in breast brachytherapy at the University of Wisconsin and Arizona Breast Cancer Specialist Centre, as well as prostate brachytherapy, skin and paediatric fellowships at Peter Maccallum Cancer Institute, Australia.
Volumetric modulated arc therapy [VMAT] involves the use of external radiation therapy beams being directed in a series of arcs or angles to allow for greater access to tumour. VMAT allows more difficult tumours, such as ones wrapped around other important structures, to be targeted precisely.
Image-guided radiation therapy [IGRT] is a radiation therapy which utilises advanced imaging equipment and computer software to accurately target tumours. This minimises the impact on surrounding healthy tissues, resulting in fewer potential side effects from treatment.
Brachytherapy is a special form of internal radiation therapy where a radioactive source is placed close to or inside the tumour.
Gynaecology brachytherapy is a form of radiation therapy used to treat cervix and endometrial cancer. It is a special form of internal radiation therapy where a radioactive source is placed closed or inside the tumour, to deliver the radiation treatment.
Dr Johann Tang is an experienced radiation oncologist in Singapore who provides quality cancer treatment using radiation therapy for patients diagnosed with various types of cancer. As the radiotherapy treatment in Singapore can be unfamiliar to patients, he will be there to provide constant encouragement and personalised care. With ethics and empathy at the core of their practice, Dr Tang and his team of capable staff strive to understand each patient’s individual needs, allowing them to provide care that is compassionate and responsive.
