Your doctor just said “Radiotherapy.” What does that actually mean?

You may have heard the word before.

Radiotherapy.

But hearing your doctor say that you may need it can make the word feel very different.

Suddenly, you want to know the in-depth details of what that term is, and that's very understandable. Let’s start with the basics.

What is radiotherapy?

Radiotherapy is a cancer treatment that uses high-energy radiation to damage cancer cells and help control or destroy them.

It can be used in different ways depending on the type and location of cancer and the treatment plan developed by the healthcare team.

For some patients, radiotherapy may be the main treatment. For others, it may be used alongside other treatments. There is no single radiotherapy journey.

Why has it been recommended to me?

Your doctor will consider your individual diagnosis and other clinical information when determining whether radiotherapy may be appropriate. This is why treatment planning matters.

The aim is not simply to give you a treatment; it is to determine the approach that is appropriate for you.

What happens next?

If radiotherapy is recommended, your healthcare team will explain the treatment process and what you can expect.

You can ask questions; in fact, you should ask:

Why is radiotherapy being recommended? What is the goal of my treatment? How will my treatment be planned?

Understanding your treatment can make an unfamiliar experience feel less uncertain.

This period can be terrifying, and it's okay to be afraid. You don’t have to pretend you’re not. Remember that another person’s experience does not necessarily predict yours. Your treatment is based on your individual circumstances.
