Mrs. Smith was also treated with radiation therapy. What is the basic mechanism of using radiation therapy as a component of treatment for breast cancer?
What will be an ideal response?
• Radiation therapy (RT) uses ionizing radiation to damage DNA and cause cell death. Due to the rapid proliferation of cancerous tissue and RT's use of oxygen to augment the damage due to radiation, RT affects these cells to a greater degree.
• RT is typically used in breast cancer to accompany the surgical resection of cancerous tissue to kill any remaining cancer cells that were not removed.
