Oncology Explained: What You Need to Know About Cancer Care and Treatment
By Dr. Sara Benson, MD – Board‑Certified Medical Oncologist
1. What Is Oncology?
Oncology is the branch of medicine focused on cancer. It involves the study, diagnosis, treatment, and prevention of cancer using various medical, surgical, and radiation-based methods. With the rise of different cancer types, oncologists play a critical role in patient care and survival outcomes.
2. What Does an Oncologist Do?
Oncologists are cancer specialists who handle everything from diagnosis to post-treatment monitoring. Their responsibilities include:
- Identifying cancer through imaging, biopsies, and blood tests
- Staging the disease and determining its severity
- Creating personalized treatment plans using chemotherapy, immunotherapy, radiation, or surgery
- Monitoring for side effects and recurrence
- Providing emotional support and guidance
3. Types of Oncology
- Medical Oncology: Uses medications like chemotherapy, targeted therapy, and immunotherapy to treat cancer.
- Surgical Oncology: Involves the removal of tumors through surgery. Often used for solid tumors.
- Radiation Oncology: Uses radiation to kill cancer cells and shrink tumors.
4. Importance of Early Detection
Early detection significantly improves treatment outcomes. According to recent research, cancers like breast, lung, and colon have much higher survival rates when diagnosed in the early stages.

- Smoking and alcohol abuse
- Obesity and sedentary lifestyle
- Exposure to radiation, carcinogens, and certain viruses
- Chronic inflammation and immune disorders
6. Recent Advances in Cancer Therapy
Modern oncology has seen a rapid rise in life-saving therapies:
- CAR-T Cell Therapy: A revolutionary treatment using the patient’s immune cells to attack cancer.
- Immunotherapy: Boosts the immune system to recognize and destroy cancer cells.
- Precision Medicine: Treatment based on a tumor’s genetic profile, improving accuracy and success rates.
7. Cancer Types You Should Know
There are over 100 types of cancer, but some require extra attention due to their aggressiveness:

- Maintain nutrition and hydration
- Follow medication and treatment schedules
- Keep regular checkups for recurrence
9. Ask the Oncologist (FAQ)
Q1: Can stress increase the risk of cancer?
While stress doesn’t directly cause cancer, chronic stress can weaken the immune system and influence unhealthy habits that increase cancer risk.
Q2: Is cancer curable?
Many cancers are curable, especially when detected early. Treatments vary depending on cancer type and stage.
Q3: How can I lower my cancer risk?
Adopt a healthy lifestyle, avoid tobacco, exercise regularly, eat a balanced diet, and get regular screenings.
10. Final Thoughts
Oncology is not just about treatment—it's about prevention, support, and education. With advancing technology and dedicated professionals, survival rates continue to improve. Be proactive about your health and get screened regularly.
