Oncologists Guide
What is an Oncologist?
An oncologist is a medical doctor who specializes in diagnosing, treating, and managing cancer. They work with patients to create treatment plans that may include surgery, chemotherapy, radiation, or other therapies. Oncologists play a critical role in cancer care, from early detection to post-treatment monitoring.
What Does an Oncologist Do?
Oncologists are responsible for:
- Diagnosing cancer using imaging, biopsies, and lab tests.
- Staging cancer to determine how advanced it is.
- Recommending treatment plans based on the type and stage of cancer.
- Administering treatments such as chemotherapy, radiation, or immunotherapy.
- Monitoring patient progress during and after treatment.
- Coordinating care with other specialists, such as surgeons and radiologists.
Some common procedures and treatments oncologists offer include:
✔ Biopsies – Removing tissue samples for cancer testing.
✔ Chemotherapy – Using drugs to kill or slow cancer cells.
✔ Radiation therapy – Targeting cancer cells with radiation.
✔ Immunotherapy – Boosting the immune system to fight cancer.
✔ Surgical oncology – Removing tumors surgically.
✔ Hormone therapy – Blocking hormones that fuel certain cancers.
Oncologist Training
To become an oncologist, a doctor must complete:
- Medical School (4 years) – A general medical degree.
- Residency (3+ years) – Specialized training in internal medicine or another related field.
- Fellowship in Oncology (2-3 years) – Intensive cancer-specific training.
- Board Certification – Passing exams to become certified in oncology.
Many oncologists continue their education throughout their careers to stay up-to-date on the latest cancer research and treatments.
Types of Oncologists
Oncology is a broad field with different specialties, including:
By Treatment Type:
✔ Medical Oncologists – Specialize in chemotherapy, immunotherapy, and targeted therapy.

✔ Neuro-Oncologists – Treat brain and nervous system cancers.
Each type of oncologist works closely with other specialists to ensure patients receive comprehensive cancer care.
Why Would I Be Referred to an Oncologist?
Your doctor may refer you to an oncologist if:

Treatments Provided by Oncologists
Oncologists use various treatments to fight cancer, depending on the type, stage, and individual patient factors. Common cancer treatments include:
✔ Chemotherapy – Uses powerful drugs to destroy or slow the growth of cancer cells. It can be administered orally, intravenously, or through injections.
✔ Radiation Therapy – High-energy radiation targets cancer cells to shrink or eliminate tumors.
✔ Immunotherapy – Boosts the body’s immune system to help fight cancer.
✔ Targeted Therapy – Uses drugs that specifically attack cancer cells while minimizing harm to healthy cells.
✔ Hormone Therapy – Used for hormone-sensitive cancers (e.g., breast or prostate cancer) to block hormones that fuel cancer growth.
✔ Surgery – Some cancers require the removal of tumors through surgical procedures.
✔ Stem Cell or Bone Marrow Transplant – Used for blood cancers like leukemia and lymphoma to replace damaged bone marrow with healthy cells.
✔ Palliative Care – Helps manage symptoms and improve quality of life in advanced cancer cases.
Common Procedures Performed by Oncologists
Oncologists perform or order various tests and procedures to diagnose and monitor cancer, such as:
✔ Biopsies – A tissue sample is taken to confirm cancer.
✔ CT Scans, MRI, and PET Scans – Imaging tests to locate tumors and track cancer spread.
✔ Endoscopy and Colonoscopy – Used to examine the digestive system for cancers.
✔ Blood Tests (Tumor Markers) – Can indicate cancer presence and progression.
✔ Bone Marrow Aspiration – Examines bone marrow for blood-related cancers.
✔ Lumbar Puncture (Spinal Tap) – Checks for cancer spread in the spinal fluid.
✔ Genetic Testing – Determines inherited cancer risks and treatment options.
Care & Monitoring by an Oncologist
An oncologist will monitor your treatment progress, side effects, and overall health through:
✔ Regular follow-up visits – To assess treatment response and adjust plans.
✔ Blood tests and imaging scans – To track tumor size and spread.
✔ Symptom tracking – Monitoring fatigue, pain, or weight changes.
✔ Medication adjustments – To minimize side effects and optimize results.
✔ Long-term surveillance – Regular screenings for recurrence even after successful treatment.
How to sync information with your oncologist:
- Keep a symptom journal to track side effects and changes.
- Use a patient portal to access test results and communicate with your doctor.
- Ask about home monitoring tools, like blood pressure cuffs or oxygen monitors, if needed.
Early Detection & Screenings
Regular screenings and early detection play a critical role in identifying health conditions before they become severe. Specialists recommend routine health assessments based on age, risk factors, and medical history to catch potential issues early.
A specialist may use various diagnostic tools, imaging, and lab tests to assess your health. Early detection allows for timely intervention, better treatment outcomes, and improved quality of life. If you have concerns about symptoms, a family history of a condition, or risk factors, scheduling a screening with the appropriate specialist is a proactive step toward prevention and early care.
Caregiver Support & Family Involvement
Family members and caregivers often play a crucial role in supporting a patient’s healthcare journey. Whether helping with scheduling appointments, managing medications, or providing emotional support, caregivers ensure patients receive consistent care.
Specialists may guide caregivers on best practices for assistance, offering education on symptoms, treatments, and daily care routines. Open communication between patients, caregivers, and medical professionals is essential for effective care coordination. If you are a caregiver, asking questions and seeking support from healthcare providers can help you better navigate your role while ensuring the patient’s well-being.
