1. Cancer Treatment
(i) Treatment: chemotherapy, co-ordination of overall treatment plan (may include other clinical specialties), after-treatment care, palliative care.

(ii) Cancer Types: breast, colon/rectum, lung, gastrointestinal, gynaecological, urological, head & neck, hepatobiliary, musculoskeletal, neurological, haematological malignancies.

(iii) Cancer Support Programmes: symptom management, infective precautions, dietary counselling, emotional counselling.

(iv) Clinical Trials

2. Cancer Screening
Screening plays a crucial role in detecting cancer in its early stages. When cancer is detected early, prompt intervention and treatment can lead to improved clinical outcomes.

International Cancer Specialists and its allied services offer a comprehensive cancer detection service, using top-of-the-line health screening and diagnostic technology. Screening procedures range from blood tests to radiological imaging, such as ultrasound scans, CT (computed tomography) scans, MRI (magnetic resonance imaging) scans and PET (positron emission tomography) scans.

Raising public awareness to recognize early warning signals is helpful, although cancer can occur in individuals with no symptoms or signs. Currently, clinical evidence best supports screening the general population for breast cancer, cervical cancer and colorectal cancer. Although screening measures for other cancers exist, there is a worldwide effort ongoing to evaluate their clinical impact.

His vision for International Cancer Specialists is to provide patient-centered cutting edge cancer care that is affordable and compassionate.

Born in Taiwan, Dr. Hsieh grew up in the United States and was educated in the United States and the United Kingdom. He attended college at Tulane University in New Orleans, Louisiana, graduating summa cum laude with a degree in Neuroscience. He went on to study philosophy and psychology at Oxford University, England on a prestigious Rhodes Scholarship. He then completed his medical training at some of the top academic institutions in the World, including a medical degree from Johns Hopkins University School of Medicine, internship and residency in Internal Medicine at Duke University and a fellowship in medical oncology at Johns Hopkins. Dr. Hsieh is certified in Internal Medicine and Medical Oncology by the American Board of Internal Medicine.

After completion of his medical training, Dr. Hsieh was active in patient care, teaching, and research in his posts as Consultant in Medical Oncology, Johns Hopkins Singapore International Medical Center and Assistant Professor in Oncology, Johns Hopkins University School of Medicine.

Dr. Hsieh has been working in Singapore since 2001 and has been active in the treatment of patients and development of novel cancer therapies. With a research interest in molecularly targeted cancer therapies and immunotherapy, he has led a number of international studies involving centers in Singapore, Hong Kong, Korea, and the United States examining novel treatments for nasopharyngeal carcinoma. Dr. Hsieh has authored a number of scientific articles, abstracts, and book chapters and has lectured extensively at regional and international medical and scientific conferences. In addition, he has received a number of awards, including a Cure for Lymphoma Foundation fellowship and a Rhodes Scholarship.

Dr. Hsieh is able to converse in English, Mandarin and Bahasa Indonesia.
