What is Deep Inspiration Breath Hold treatment?
While radiation therapy is considered a safe and important treatment for breast cancer, it has the potential in some patients with left-sided breast cancer to cause damage to the heart in the years following treatment. This is because the planned radiation beam may come in contact with the heart. As each person’s size, shape, anatomy and tumour location differs, we are unable to know if this is the case for an individual until they have had their CT planning scan.
If the heart does fall within the planned radiation field, radiation oncologists can use various techniques to minimise the risk of the radiation beam intersecting a portion of the heart. Deep Inspiration Breath Hold (DIBH) is the most efficient, safe and simple of these techniques.
What happens during treatment?
Treatment is delivered using technology that is programmed to match each patient’s breathing cycle. This treatment is known as 'Deep Inspiration Breath Hold'.
When a patient holds their breath, there is an increase in the natural space between the heart and the radiation dose. Patients only need to be able to hold their breath for a short period (around 20 – 30 seconds) several times during treatment.
The specialised equipment will only allow the treatment machine to deliver radiation whilst the patient is holding their breath.
Comparison between free breathing and DIBH -
Figure 1 (Above left): Free breathing – the radiation beam comes close to the heart
Figure 2 (Above right): Deep inspiration breath hold – the heart remains outside radiation field
The patient is in control
The patient can simply talk to our team, or use a small hand held controller if, at any time, they wish to stop treatment. This gives the patient the unique opportunity to be in complete control.
Why consider DIBH?
- Most efficient technique to reduce the risk of radiation to the heart in left-sided breast cancer
- Complete control and the option to stop at any time
- Non-invasive and suitable for almost everyone
