Oesophagus Radiotherapy
Radiotherapy uses targeted radiation beams to kill cancer cells in the oesophagus. The radiation harms the cancer cells’ DNA, stopping them from growing or multiplying. Over time, this helps shrink or destroy the tumour. The treatment aims to target the cancer while keeping healthy nearby tissue safe.
Here’s what a patient can expect during the process:
Meeting your Doctor
Before treatment starts, you’ll have a chat with your doctor. They will explain the treatment, possible side effects, and ask you to sign a consent form. This meeting can be in person or over the phone.
Mould room appointment (if required)
If you need a mask for your treatment, your first appointment might be with the mould room team. They will make a special mask to keep your head and shoulders still during radiotherapy. This helps make sure the treatment is accurate. If you have any worries about the mask, please talk to your doctor.
The resource below explains the procedure in more detail which you may find helpful.

In this video you can see for yourself what to expect when you come for your radiotherapy mask moulding and understand a little more about how and why we do this.
Leeds Radiotherapy Mould Room
Did you get here okay today?
Yes thank you, the journey was fine.
Oh, that’s good.
You get parked okay as well?
Yeah, that’s fabulous.
Come on through.
And this is Meera, my colleague, who I’m working with today.
Okay, so we’re going to make a mask for you today that looks a little bit like this.
So it’s still nice and flexible and we leave plenty of room for you to breathe around your nose and mouth area.
The purpose of the mask, it just keeps you nice and still, when you are having your radiotherapy treatment, making sure that we can get you in the same position each time you come, which makes sure that the radiation is going exactly where we expect it to go to.
So it starts out as a flat sheet of plastic like those ones under there. Meera is warming it up in our bath which makes it go all see through soft and stretchy, kind of feels like a gel.
So in a moment, what we’ll do we’ll get you changed into a gown and we’ll get you laid on our bed nice and straight.
We’ve got something that goes under your head, something that goes under your knees and will get you as comfortable as possible.
And we do pop a cap over your hair. It just helps us lift the mask off at the end.
And then we’re going to give you some hand grips to hold on to.
We need to make sure you’re nice and straight on the bed using this laser.
We’ll move you, you lay nice and heavy. That’s perfect. Then what we do is we take the material out of the water, dry it off, stretch it over.
So it just feels a little bit warm and damp when it first goes on. Kind of like a warm towel and you’ll just feel us mould it perfectly to your shape. Breathe away as normal, Okay.
And now we’re just going to mould it perfectly to your shape. You’re doing really well there, it takes about 7 minutes to set all together.
We do pop some cool pads on, to just help speed up that process and then once we’re happy, we’ll be putting your ID on, some stickers and tape.
Just a few pen marks to help line you up.
Once we’re happy, we’ll lift it up, try it back on to make sure it fits nicely once it’s set.
We are all done.
And then you’ll be having a CT scan after this.
Planning scan
If you need a mask for your treatment, your first appointment might be with the mould room team. They will make a special mask to keep your head and shoulders still during radiotherapy. This helps make sure the treatment is accurate. If you have any worries about the mask, please talk to your doctor.
Small tattoos may be placed on the skin around the area that will receive radiation. These markings help ensure that radiation is delivered to the same spot each time.
Radiotherapy
Radiotherapy for oesophagus cancer is usually given 5 days a week (Monday to Friday). The number of treatments will depend on the doctor’s recommendation. The therapeutic radiographers will accurately position you on the treatment couch. This will be the same position which you laid down in for your planning CT scan.
The linear accelerator will rotate around you and deliver treatment from different angles. You won’t feel the radiation, but you might hear some noises as the machine operates. Each session takes around 15 to 20 minutes. However, the actual radiation only takes a few minutes. You’ll need to stay still during the treatment, but you won’t feel pain or discomfort during the process.
Side Effects
Even though radiation targets the tumour, it can also affect healthy tissue nearby. Side effects usually start after a few treatments and can be different depending on the area being treated.
Common side effects of oesophagus radiotherapy include:
- Tiredness (Fatigue): Tiredness is one of the most common side effects, and it tends to build up over time during treatment.
- Skin Changes: The skin in the treated area may become red, dry, or irritated, like sunburn. You might also experience itching or peeling. See the link below advising you on how to look after your skin during and after radiotherapy treatment.
- Difficulty Swallowing (Dysphagia): The radiation can sometimes cause inflammation in the oesophagus, making swallowing harder or more painful. You might need to adjust your diet to softer foods. It is important to tell your radiotherapist if you are struggling to eat or drink.
- Sore Throat: Radiation can cause a sore throat, mouth dryness, or irritation if treatment is around that area.
- Nausea or Vomiting: Some people feel nauseous, especially if the tumour is near the stomach or if the treatment affects the digestive system.
Please Note
Most side effects improve 10-14 days after treatment ends. Your healthcare team will be there to manage any side effects and provide support during and after your treatment.
Please inform your radiotherapist if you are experiencing any side effects.
