Radiation Oncology

Treatment Process

The treatment through radiation therapy has the following steps:

• Simulation: This is a type of rehearsal done by radiation oncologists before delivering the actual treatment. It involves the use of imaging techniques, such as CT scan, MRI, and X-ray, to determine the size and location of the tumor.
• Appropriate positioning: The patient is positioned in a way that the radiation is directly guided on the tumor with minimal damage to the healthy tissues.
• Delivering the radiation therapy: Radiation therapy may be delivered through external beam radiation therapy or brachytherapy. External beam radiation therapy involves guiding the radiation on the tumor from a machine present outside the body. Brachytherapy involves placing the seeds containing radioactive material into or near the tumor site to kill the cancer cells.
