What are the different types of radiation therapy?
Radiation therapy can be delivered:
- From a machine outside of the body – this is called external-beam radiation therapy
- By placing radioactive material inside the body – this is known as brachytherapy
- By giving a radioactive substance by mouth or into a vein – the substance then travels in the blood to the tumour (known as systemic radiation therapy)
The type of radiation therapy you are recommended depends on many factors, including:
- The type of cancer
- The size of the cancer
- The cancer’s location in the body
- How close the cancer is to normal tissues that are sensitive to radiation
- How far into the body the radiation needs to travel
- Your general health and medical history
- The combination of other cancer therapies like chemotherapy, surgery and immunotherapy
Deep Inspiration Breath Hold for Breast Cancer patients - How DIBH works / What is it?
Deep Inspiration Breath Hold (DIBH) is a technique that reduces the risk of radiation contact to the heart.
For women with left-sided breast cancer, a major concern is the dose of radiation delivered to the heart could increase the risk of heart disease.
DIBH is the most efficient way to minimise this risk; however, there are other methods to reduce the radiation dose to the heart.
DIBH is a technique that requires you to hold your breath during your CT scan (measurement scan) and each daily treatment.
You need to be able to hold your breath for a short period, around 20 seconds, several times during each daily treatment.
