1. Overview

This course introduces the role of radiotherapy in cancer treatment, explains the physics behind how radiation interacts with human tissue, and outlines how radiation damages tumor cells. It provides a foundational understanding of the scientific principles guiding modern radiation therapy.

2. Key Learning Objectives

After this course, you will be able to:

  • Define radiotherapy and describe its purpose in cancer treatment.

  • Explain how ionizing radiation interacts with biological tissue.

  • Describe the mechanisms through which radiation damages and kills tumor cells.

  • Understand the relationship between radiobiology, radiation physics, and treatment planning.

3. Why You Should Attend (The Benefits)

  • Build a strong foundation in the scientific principles behind radiation therapy.

  • Gain clarity on how radiotherapy works and why it is used in cancer care.

  • Prepare for more advanced study in oncology, radiobiology, or medical physics.

4. Topics Discussed

  • Introduction to cancer and the role of radiotherapy

  • Overview of treatment modalities in oncology

  • Fundamentals of radiation physics

  • Interaction of radiation with living tissue

  • Mechanisms of radiation-induced tumor cell death

  • Importance of radiobiology in treatment planning
