Benjamin W. Teh is a hematologist-oncologist based in Grattan Street, Melbourne, VIC 3000. He looks after people who have conditions that affect the blood and the immune system, as well as cancers that can start in the blood or bone marrow. In practice, this often means supporting patients through both treatment and the tough “in-between” moments when the body is coping with side effects and infection risk.
Benjamin works with adults and patients who may have ongoing blood disorders, including chronic leukaemias and lymphomas. He also helps manage multiple myeloma, where treatment can be a long journey. At times, care includes planning and follow-up around bone marrow transplant, because that can bring special monitoring needs and a careful eye on recovery.
A big part of the work is also about infections, especially when the immune system is weak. This can include problems like febrile neutropenia and agranulocytosis, where fevers can be a sign the body is struggling to fight germs. He also helps manage serious infections such as sepsis, pneumonia, and meningitis. For people with lower immunity, fungal and viral infections can happen as well, including aspergillosis, cytomegalovirus infections, and cryptococcosis. Viral illnesses like flu, COVID-19, and chickenpox are also covered, along with hepatitis issues such as hepatitis B.
There are other complex immune and bowel conditions that can come up in this kind of care too. For example, secondary immunodeficiency can affect how someone handles infections day to day. Some patients may also need support when they have complications related to the gut, or when infections and inflammation show up after treatments.
While every case is different, the goal stays the same: clear information, steady care, and close monitoring when it matters most. Benjamin focuses on practical management and safety, especially for people who are more at risk of getting unwell quickly. If you’re dealing with a blood cancer, a long-term blood disorder, or an infection on top of treatment, you need a team that understands how all of it fits together.
