Radiation therapy or radiotherapy is a common treatment for lung cancer. The treatment is painless. However, there are some side effects which are associated with radiation therapy, and they are different for each person. Some people have many side effects; others have hardly any.9
- The side effects of radiation therapy for lung cancer usually come on slowly. They may last for a few weeks after treatment has ended. Once the treatment is over, the side effects will gradually get better.10 A small number of people have long term side effects, which develop up to 2 years after treatment has finished.10
- Some of common side effects include:10,11
- Fatigue: This treatment-related fatigue might feel like an overall lack of energy and might persist for many weeks or even months.12 Below are a few tips to help combat fatigue:
- Skin reaction: Most people develop a skin reaction in the area being treated, ranging from mild redness to blistering and peeling.11,13 The reaction begins a few weeks after the beginning of a radiation therapy course, and will usually resolves within a few weeks of finishing therapy.9 Below are a few advice for taking care of skin reaction:12
- Sore throat and trouble swallowing: This may happen if the area being treated is close to the throat or oesophagus. Symptoms usually occur 2 to 3 weeks into therapy and subside a few weeks after completing treatments.9 Below are a few tips to help manage the problem:12
- Cough: Patients can develop a cough which maybe dry and tickly or even with blood.13 It may be relieved with sipping a drink or taking cough medicine. The cough should pass when the treatment is over. However, if cough persists and the sputum changes colour, becomes thicker or patients have a fever, please consult a doctor. It may be a sign of infection.13
- Chest pain: Patients may develop chest pain, often within a few weeks of starting the treatment.12 It should go away by itself but remember to tell doctors just in case the chest pain is caused by something else.
- Nausea and vomiting: Radiation therapy can cause nausea, vomiting, or both. These symptoms may occur 30 minutes to many hours after a radiation therapy session ends.9 The best way to keep from vomiting is to prevent nausea. One way to do this is by having bland, easy-to-digest foods and drinks that do not upset the stomach. Besides, try to relax (such as reading a book or listening to music) before each radiation therapy treatment may help a patient feel less nausea.9
