What happens during and after radiotherapy treatment

Patients will lie on a treatment couch wearing a special radiotherapy mask that

is attached to the couch. The radiographer will take a few minutes making sure that

the patient is in the correct position., and will then leave the room. Two way

conversations can take still place.

Some radiotherapy machines move around during treatment; others will look more

like a CT scanner.

Radiotherapy is commonly used after surgery to destroy any remaining tumour cells

in patients older than 8-10 years.

Finishing radiation is a real milestone. But it is usually not the day your body starts feeling better.

One of the most surprising parts of radiation therapy is the lag after the final treatment. Radiation effects are cumulative, and the tissues in the treatment area can continue reacting for days, and sometimes a week or two, after the last session.

Depending on the area treated, fatigue, skin changes, soreness, swallowing difficulty, or urinary and bowel symptoms may plateau or even worsen temporarily before they begin improving. Think of it like a sunburn that continues developing after you have come inside. Even when this is explained at the beginning of treatment, it can be hard to remember weeks later when you are exhausted and expecting the final session to bring immediate relief. When symptoms continue afterward, it can feel like you are going backward.   You are not.

For many people, the first week or two after radiation is still part of the hardest stretch. Improvement often begins gradually, and recovery is not always a straight line. A better day followed by a harder day does not necessarily mean something has gone wrong.

A few things that can help:

  • Keep any help you have arranged in place for the first week or two after treatment ends rather than assuming you will no longer need it on your last day.
  • Do not schedule every postponed responsibility for the week after you finish. Give yourself a planned grace period.
  • Keep following the skin care, mouth care, nutrition, hydration, and other instructions your team gave you until they tell you otherwise.
  • Keep tracking your symptoms for at least the first couple of weeks after treatment. A quick daily note about energy, pain, skin changes, sleep, mood, or treatment-specific symptoms can help you see whether things are improving, staying the same, or getting worse.
  • Keep your radiation oncology team’s number handy. Treatment may be finished, but you are still their patient during recovery.

You are not failing at recovery because you do not feel better right away.   If your symptoms are worsening, difficult to manage, or concerning to you, contact your radiation oncology team rather than trying to push through alone.’
