Sarcoma Radiotherapy
Sarcoma is a cancer that can grow in bones or soft tissues like muscles, fat or connective tissue. Radiotherapy is used after surgery, or instead of surgery.
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 your treatment needs a special mould to keep you still, you’ll visit the mould room first. Technicians will make a custom mould to keep the area being treated still during your radiotherapy treatment. This helps make sure the radiation hits the right spot.
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
Before treatment begins, you’ll have a planning scan. This usually takes place a few weeks before the treatment starts. During this session you will be laid down in the treatment position, this will depend on the area which we are treating.
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 sarcomas 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 sarcoma 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.
- Swelling or Soreness: If the tumour is located near muscles or other soft tissues, you might experience some swelling or discomfort in the treated area.
- Pain or Tenderness: The treated area may feel sore or tender, particularly if the tumour is near the skin or deep inside the body.
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.
