Types of Radiation Therapy
Radiation therapy can be delivered two ways - externally and internally
- External beam radiation therapy delivers radiation using a linear accelerator
- Three-dimensional conformal radiation therapy (3D-CRT)
- Intensity modulated radiation therapy (IMRT)
- Internal radiation therapy, called brachytherapy or seed implants, involves placing radioactive sources indside the patient
The type of treatment used will depend on the location, size and type of cancer.
