You might have trouble swallowing (dysphagia) during and after radiotherapy treatment to the chest. There are a number of things that you can do to help.
Radiotherapy to the chest might cause swelling and soreness in the throat. This side effects usually starts with a feeling of a lump in the throat.
Whether you have problems swallowing depends on where exactly you are having treatment and if your throat is in the radiotherapy field. It also depends on the dose of treatment. Difficulty swallowing may be worse and can last longer if you have chemotherapy at the same time as radiotherapy.
As with all radiotherapy side effects, they tend to build up over time. This means you might experience problems after about a week and then this can continue for around 2 weeks after radiotherapy.
In some hospitals, you'll see a dietician weekly during treatment. If not you can ask to see a dietitian if you're having problems.
