Should it be necessary, your doctors will be able to give you advice on the management of these, often mild, side effects.
Let’s take a look at some of these acute side effects.

In addition, some patients may also notice that they tire more easily, develop a mild dry cough. It would be advisable to rest more or take some time off work if you find yourself getting out of steam when treatment progress.
Many patients experience transient mild sharp discomfort in the breast or chest wall that have been operated on. These symptoms often starts before radiation and does not usually mean that something serious is happening. These intermittent episodes of pain usually becomes less frequent and less intense as time passes. However, do let your doctor know of these pain so that the appropriate pain killer may be given if the pain troubles you.
