Radiation Side Effects
Radiation Side Effects
The radiation side effects experienced by the normal body tissues during and after radiotherapy can be loosely divided into Acute and Late effects.
Acute radiation side effects constitute the acute reaction occurring during radiation and in the immediate weeks and months following treatment.
Acute Radiation Side Effects
Radiation treatment is painless and without sensation, with the exception of some mechanical sounds produced by the treatment machine associated with the start and finish of the treatment. Many patients receiving radiation therapy will experience very little reaction, but in most the normal tissues will develop some degree of radiation reaction. This varies in amount and type, depending on the part of the body treated and the amount of normal tissue included in the radiation treatment.
The degree to which individuals experience reaction varies considerably, but this section will deal with some general principles of radiation reaction. Where large areas of a patient are treated, such as the whole abdomen or chest, the reaction experienced will be mainly of a general nature. When small areas are treated the reaction will be confined to that area of the body that is radiated and to the individual tissues included in the treatment volume. Any general reaction will be much less or absent altogether.
