About internal radiotherapy
This section gives information about internal radiotherapy.
Not everyone needs internal radiotherapy, so you’ll only need to read this section if it’s relevant for you.
There are two types of internal radiotherapy:
Brachytherapy - This is when a solid radioactive source is placed into or close to the tumour.
Radioisotope treatment - This is when a liquid source of radiation is used inside the body. It's also called radionuclide therapy.
Your healthcare team will be able to provide you with more detailed information about these types of radiotherapy.
