FAQ's Related to Hematologist

A hemato-oncologist specialises in diagnosing and treating blood disorders and cancers, including leukaemias, lymphomas, myeloma, and other blood-related conditions.

You should consult a hemato-oncologist if you have abnormal blood counts, unexplained bruising or bleeding, persistent fatigue, swollen lymph nodes, or a diagnosis of blood cancer.

Diagnosis may involve blood tests, bone marrow biopsy, imaging scans, and genetic or molecular testing to determine the type and stage of the disease.

They provide chemotherapy, targeted therapy, immunotherapy, CAR T-cell therapy, bone marrow/stem cell transplantation, and supportive care to manage symptoms and complications.

CAR T-cell therapy is an advanced immunotherapy that modifies a patient’s T-cells to target and kill cancer cells, used mainly for certain types of leukaemia and lymphoma.

Follow-up frequency depends on your diagnosis and treatment plan, ranging from weekly during intensive therapy to monthly or quarterly for monitoring remission.

Yes, getting a second opinion is common, especially for complex or rare blood cancers, to explore all treatment options.
