When Should You See A Medical Oncologist?
It is advisable to consult a medical oncologist if you or a loved one receive a diagnosis of cancer, or if initial diagnostic investigations—such as abnormal blood panels, radiological scans, or tissue biopsies—indicate a high suspicion of malignancy. A medical oncologist is a physician who specialises in diagnosing, evaluating, and managing cancer using systemic therapies such as chemotherapy, targeted agents, hormonal therapies, and modern immunotherapies.
You should also schedule a consultation if you require a comprehensive second opinion on your current treatment plan, want to explore advanced genomic profiling for precision targeted medicine, or need clarity on the integration of surgical, radiological, and systemic treatment approaches. Even in cases where cancer treatment has been completed, regular follow-ups with an oncologist are essential for monitoring potential recurrences and managing long-term side effects.
Treatment Guide (Non-Surgical): Understanding Chemotherapy, Immunotherapy, and Targeted Therapy
Non-surgical oncology relies on systemic treatments administered orally or intravenously to target cancer cells throughout the body:
- Chemotherapy: Traditional systemic pharmacological treatment designed to destroy rapidly dividing cancer cells or inhibit their replication.
- Immunotherapy: Advanced biological treatments that harness and stimulate the patient’s own immune system to recognise and destroy malignant cells.
- Targeted Therapy & Genomics: Precision medicine that targets specific genetic mutations, biomarkers, or proteins within cancer cells to block tumor growth while sparing surrounding healthy tissue.
Treatment Guide (Surgical & Multidisciplinary): Surgical Resection and Multidisciplinary Tumor Boards
Systemic oncological treatment frequently works hand-in-hand with surgical and radiation interventions:
- Surgical Resection: The physical removal of a solid tumor and surrounding healthy tissue or lymph nodes by a surgical oncologist or subspecialised surgeon.
- Multidisciplinary Tumor Boards: Collaborative review sessions where medical oncologists, surgical oncologists, radiotherapists, pathologists, and radiologists collectively evaluate complex cases to devise the safest, most effective integrated treatment strategy.
