Proton therapy has practically no side effects, so it is successfully performed on an outpatient basis. If a side effect occurs, then this is a local reaction, for example, irritation of the skin or mucous membranes on the irradiated area of ​​the body. There may also be a lack of appetite, general weakness, and fatigue. Treatment of the prostate may cause burning when urinating. However, these side effects are easy to control and disappear within 2-3 weeks.
In WPE, doctors inform patients about the possibility of these reactions, tell them how to avoid side effects, and, if necessary, quickly heal. All patients are supervised by nurses from the outpatient nursing department, who provide all the necessary assistance and psychological support.
