Breast boost radiotherapy

I start radiotherapy on Tuesday. Iwas told 5 days full breast radiotherapy followed by 4 days breast boost to tumour bed. I’m now getting the boost first followed by full breast the next week. What is the significance of this?
Does it make a difference. Thanks.

Hello katharin

Thanks for posting.

We’ve had some technical issues with the forum this week, so apologise for the delay in replying to posts in the Ask Our Nurses area of the forum.

A boost of radiotherapy is typically given after whole breast radiotherapy.

There has been some research which has looked at giving the boost at the same time as whole breast radiotherapy as a way to decrease the time period over which it’s given and reduce side effects.

However, we’re unsure why a boost would be given first. As you’ll have started your radiotherapy by now, do ask your radiotherapy team about the radiotherapy regime you have been prescribed and the reasons why it’s being given in this way.
