Catherine M. Shannon is an Oncologist based in Brisbane, QLD, Australia. She looks after people dealing with cancer and some other serious medical conditions that can affect the whole body. Her clinic work is based in Brisbane, and the focus stays on getting you through the next step safely.
In oncology, patients can come in at very different stages. Some are starting treatment and are still trying to understand what’s going on. Others are already in the middle of chemotherapy or follow-up care, and they need help managing side effects. Catherine supports people with cancers such as ovarian cancer, breast cancer, endometrial cancer, and testicular yolk sac tumour. At times, the care can also include dealing with ascites, which is fluid build-up in the abdomen and can make day-to-day life feel harder.
On some visits, the worry is not only the cancer itself. Febrile neutropenia is one example. It’s a fever with a low white blood cell count, and it needs fast attention because infections can become serious. Catherine’s role is to help assess symptoms quickly and guide treatment and monitoring.
Not all cases are typical cancer stories. Catherine also cares for people with rare, complex conditions like glycogen storage disease type 6. She may also support patients with osmotic demyelination syndrome, which can be linked to shifts in body salt levels and can affect the nervous system.
Over time, she builds a steady, practical approach to care. That can mean explaining what’s happening in plain language, talking through treatment options, and focusing on comfort and safety. Patients often need more than just a plan on paper. They need clear steps, good follow-up, and help making sense of lab results, scans, and what to watch for at home.
Education and training details aren’t listed here, but Catherine works in a field where ongoing learning matters. She stays up to date with medical research so care decisions are based on the latest evidence and current practice.
She also has involvement with clinical trials, when they’re a good fit for the person and their situation. Clinical trials can offer options in some cases, and Catherine helps explain what participation usually involves, including the risks and benefits in a straightforward way.
