What Is Medical Oncology?
Medical oncology specializes in the diagnosis and treatment of cancer using various medical therapies, including:
- Chemotherapy
- Immunotherapy
- Targeted Therapy
- Hormonal Therapy
Oncologists also collaborate with other specialists, such as surgeons and radiation oncologists, to provide comprehensive cancer care, including managing side effects and offering supportive care to enhance the quality of life for patients.

How Is Cancer Treated in Medical Oncology?
- Chemotherapy
- Purpose: Uses drugs to kill or slow the growth of cancer cells.
- Administration: Orally, intravenously, or via injection.
- Combination: Often paired with surgery or radiation.
- Radiation Therapy
- Purpose: High-energy rays target and destroy cancer cells.
- Application: Delivered externally or through internal devices.
- Collaboration: Requires coordination with nuclear medicine specialists and surgeons.
- Targeted Therapy
- Purpose: Drugs focus on specific molecules driving cancer growth.
- Combination: Often used with chemotherapy or radiation.
- Immunotherapy
- Mechanism: Stimulates the immune system to recognize and attack cancer cells.
- Benefits: Enhances the body’s natural defenses.
- Hormonal Therapy
- Purpose: Blocks hormones fueling cancer growth.
- Example: Used frequently for breast and prostate cancers.
- Palliative Care
- Focus: Improves quality of life by managing symptoms like pain, nausea, and fatigue.
- Role: Provides comfort for patients with advanced cancer.
- Clinical Trials
- Purpose: Tests new treatments or therapies.
- Participation: Offers access to cutting-edge care, though risks and benefits must be evaluated.
Supportive Care in Oncology
