What is oncology?
Oncology is the branch of medicine that focuses on the study, diagnosis, treatment, and management of cancer. The term is derived from the Greek word onkos, which refers to a tumour or mass.
Medical specialists trained in oncology provide care for individuals at risk of cancer, patients undergoing treatment, and those recovering or living with cancer after treatment. Along with nurses, pharmacists, social workers, and other healthcare professionals, oncologists form an important part of a patient’s cancer care team.
Who is an oncologist?
An oncologist is a medical specialist who diagnoses, stages, and treats cancer. Oncology is the branch of medicine dedicated to understanding and managing different types of cancer through specialised treatments and patient care.
Consulting an oncologist allows patients to receive guidance and treatment from a doctor experienced in cancer care. Oncologists also help patients manage the emotional challenges, stress, and anxiety that can arise during diagnosis and treatment, offering support throughout the entire care journey.
What does an oncologist do?
Oncologists manage cancer care from diagnosis through recovery or palliative support. Their responsibilities typically include:
- Conducting and reviewing diagnostic tests such as biopsies and imaging scans
- Determining the type and stage of cancer
- Designing personalised treatment plans
- Administering therapies such as chemotherapy or immunotherapy
- Monitoring treatment response and managing side effects
- Coordinating care with surgeons, radiologists and other specialists
- Providing emotional support and counselling to patients and families
Their role extends beyond medical treatment to comprehensive patient care.
Types of oncologists
Oncology is divided into specialised branches based on treatment methods.
| Type of oncologist | Primary focus |
| Medical oncologist | Treats cancer using chemotherapy, targeted therapy, immunotherapy and hormonal therapy |
| Surgical oncologist | Performs surgery to remove tumours and cancerous tissues |
| Radiation oncologist | Uses radiation therapy to destroy cancer cells |
| Paediatric oncologist | Treats cancers in children |
| Haematologist-oncologist | Manages blood cancers such as leukaemia and lymphoma |
Often, multiple oncologists collaborate to provide comprehensive cancer care.

Questions to ask your oncologist
Preparing questions before meeting an oncologist can help patients better understand their diagnosis, treatment options, and overall care plan. Here are some important questions you may consider asking during your consultation:
- Understanding the diagnosis: Where is the cancer located, how large is the tumour, and what stage of cancer has been diagnosed?
- Knowing treatment options: What treatment methods are recommended, how long is the treatment expected to continue, and will additional tests be required during the process?
- Discussing recovery chances: What are the survival rates or expected outcomes for this type and stage of cancer?
- Managing daily life during treatment: Will the treatment affect daily activities, work routines, energy levels, or overall lifestyle?
- Understanding fertility impact: Could the treatment affect fertility or future family planning options?
- Planning follow-up care: How often will follow-up appointments, scans, or monitoring be needed after treatment begins?

- Exploring emotional support: Are counselling services, support groups, or mental health resources available for patients and families?
- Communicating with family: How can patients discuss their diagnosis and treatment journey with family members in a supportive and informed way?
The impact of today’s oncologists on cancer treatment
Modern oncologists are transforming cancer care through personalised medicine, targeted therapies and advanced diagnostic techniques. Breakthroughs in immunotherapy and precision medicine have significantly improved survival rates for many types of cancer.
By integrating research, technology and compassionate care, oncologists continue to improve treatment outcomes and patient experiences. Their work not only saves lives but also enhances long-term quality of life for survivors.
Other oncology professionals
Along with oncologists, several other specialised healthcare professionals contribute to cancer treatment and patient care. Specially trained oncology nurses may administer chemotherapy and other treatments, help manage symptoms and side effects, and provide guidance and emotional support to patients throughout treatment.
Cancer care teams may also include:
- Advanced practice providers: Nurse practitioners and physician associates who assist in treatment planning and patient care management.
- Patient navigators: Professionals who help patients understand treatment processes, appointments, and healthcare coordination.
- Oncology social workers: Specialists who provide emotional, social, and practical support to patients and families.
- Genetic counsellors: Experts who assess inherited cancer risks and guide patients on genetic testing and prevention strategies.
- Clinical pharmacists: Healthcare professionals who manage cancer-related medications and monitor drug safety and effectiveness.
- Registered dietitians: Nutrition specialists who help patients maintain proper dietary support during treatment and recovery.
- Radiologists: Doctors who use imaging techniques to diagnose and monitor cancer conditions.
- Pathologists: Specialists who examine tissues and laboratory samples to identify and confirm cancer diagnoses.
- Mental health professionals: Counsellors and psychologists who support patients in managing stress, anxiety, and emotional challenges during treatment.
Conclusion
Oncologists play an essential role in the diagnosis, treatment, and long-term management of cancer through specialised medical care and patient support. From identifying cancer in its early stages to guiding patients through advanced treatment options, their expertise has a major impact on treatment outcomes and recovery.
They also help patients understand diagnostic reports, coordinate care with other specialists, and provide emotional guidance throughout treatment and follow-up care.
For medical professionals planning higher studies, upgrading facilities, or expanding oncology practices, funding solutions such as a loan for professionals can offer valuable financial support. A well-planned approach to healthcare finance can further help ensure sustainable practice growth and long-term professional development.
