Early side effects are temporary and affect most patients. The side effects generally develop during the second half of the course of treatment or after treatment has finished. Sometimes side effects can last for several weeks however usually settle within three to four months.
Effects on the skin
Towards the end of treatment some patients may experience changes in the skin over the area that has been treated. The skin may:
- feel tight and uncomfortable
- become pink or red
- become dry and flaky
Your skin reaction may be worse and develop earlier if you are also having chemotherapy.
Your skin will be monitored by your radiographers during radiotherapy and you will be given advice on skincare. You will also be seen once a week in a radiotherapy clinic by your oncologist, the nurse specialist or specialist radiographer who will examine your skin and advise on any creams if necessary.
We recommend that you take special care of your skin during and up to six weeks after your radiotherapy as the reaction may continue after treatment has finished.
- Keep the area cool. Wear loose, preferably cotton clothing that does not rub the skin and will allow air to circulate.
- Do not expose the treated area to the sun.
- Whilst in the sun the treated area should be covered completely or a high protective factor sun cream (25 or above) should be applied. Do not use a sunbed as this could make the reaction worse.
- Do not soak the area in the bath or under a long hot shower. You may wash your skin in the treated area using a simple, unperfumed soap, applied gently with your hands and rinse well with warm water. Avoid using flannels or sponges. Pat the area dry with a soft towel or let the skin dry naturally.
- Do not use talcum powder, bubble baths, bath salts, shower gels or body lotions on the treated area as they tend to be highly perfumed and can dry or irritate the skin. You may be given a moisturising cream to soothe the skin, from the radiographers or nurses, or your oncologist may prescribe a cream if needed.
Tiredness and Fatigue
Radiotherapy can sometimes make you feel very tired especially towards the end of your course of treatment and for a number of weeks after. It may be a while before you feel able to do some of your usual activities. You should rest as much as you need to although gentle exercise may help. Fatigue is something nearly everyone with cancer feels. It affects people differently and it is important to tell the health care team if you are feeling more tired than usual. There are some physical causes, such as anaemia that are readily treatable.
Please ask for a booklet on fatigue at the Information Centre in NCCT which will give you tips to help with this.
Your treatment may make you feel more breathless than usual. There are lots of things you can do to make yourself feel better. For example:
- Plan ahead. Be realistic about what you can do. Concentrate on the things that are important to you.
- You may be able to sit down for some tasks, such as preparing food.
- Avoid bending and stretching.
You may get a cough, or if you already have one, radiotherapy may make it worse. It is also normal to cough up a lot of sputum. Please advise your CHART radiographer, oncologist or nurse specialist if:
- You cough up sputum which is coloured or blood stained as you may have an infection that requires medication
- Your cough stops you from sleeping
Swallowing and eating problems
Radiotherapy to your chest can cause internal inflammation and may make it difficult or sore when you swallow. It can also feel as if there is a “lump” in your throat. You may have a feeling of indigestion or heartburn. Please tell your radiographer, oncologist or the nurse specialist as they may be able to offer you some medication to help or arrange for you to see a dietician. You may not feel much like eating, but it is important to try.
Try these tips:
- If your throat is dry, it may help to drink more liquids. Carry a small bottle of water with you to sip.
- Eat little and often.
- Eat a bit of what you fancy!
- Try soft or runny foods such as milk puddings, pasteurised yoghurts, soft cheese and mashed foods. Soups and meal replacements (e.g. Complan) are also good.
- If you have a food processor, try puréed food.
- You can make soft food more nourishing by adding things like butter, cooked eggs, cream, sauces, gravy, mashed or minced meat or fish.
- Take tepid food and drinks
- Avoid highly spiced foods
- Don’t eat jars of baby food - they aren't suitable for adults.
- If you're too tired to cook, try a ready made meal, cold food or ask someone else to cook for you.
- If you are also having chemotherapy there may be some foods you should avoid. Your chemotherapy doctor or nurse will tell you more about this.
How else can I help myself during treatment?
- Don’t try to lose weight.
- Try not to smoke. It can make your side effects worse. Please ask if you need help with stopping smoking.
- Tell us if you are worried about your side effects, if you feel unwell or if you have any problems or questions about your treatment.
You will be seen by a member of your specialist team once a week during your treatment. This will be an opportunity to discuss any concerns or problems you may have.
