Hao-wen W. Sim is an oncologist based in Darlinghurst, NSW. You can find the practice at 370 Victoria St, Darlinghurst, NSW 2010, Australia. Hao-wen works with people who are dealing with cancer, and also with families who are trying to understand what comes next.
Cancer care can feel overwhelming. Over time, Hao-wen focuses on clear, practical support around diagnosis, treatment planning, and follow-up. In many cases, that means helping people think through options and balancing treatment goals with day-to-day life. At times, it also means coordinating care with other health professionals, so patients get a steady, joined-up plan.
Hao-wen’s work covers a range of cancers and complex conditions. This includes cancers that affect the brain and nervous system, such as brain tumours and gliomas, including glioblastoma and astrocytoma. They also look after people with tumours near the pituitary and hypothalamus. For cancers outside the brain, care can include renal cancers like renal cell carcinoma, plus cancers of the lung and liver, including lung metastases and liver cancer. Gastrointestinal cancers may also be part of the picture, such as oesophageal cancer, gastro-oesophageal junction cancer, stomach cancer, and pancreatic cancer.
Sometimes cancers spread, and sometimes they come with other challenging factors. Hao-wen helps patients understand what the cancer means for symptoms, scans, and treatment choices. They also focus on what to watch for during treatment, and how to respond if things change.
There’s no one “right” path for everyone. Treatment often depends on factors like the type of cancer, where it is, and how it behaves. Hao-wen supports shared decision-making, so patients can ask questions and feel more confident about decisions, whether that’s starting treatment, changing course, or thinking about supportive care alongside anti-cancer treatment.
Clinical trials can be an option for some people, depending on the situation. When relevant, Hao-wen and the wider team can talk through what might be available and what it could mean in real terms. The goal is always the same: care that fits the person, not just the diagnosis.
Hao-wen Sim brings a steady, patient-centred approach to oncology, with a focus on getting you through each step with less confusion and more clarity.
