In external beam radiotherapy for localized prostate cancer, acute toxicities are typically transient and mild. These symptoms will disappear within 4–8 weeks after external beam radiotherapy. Some patients might suffer from proctitis with bloody stools as late rectal toxicity. Therefore, it has been shown that external beam radiotherapy has a more pronounced negative impact on bowel function compared with other treatment modalities. However, the recent development of modern beam delivery techniques, including intensity‐modulated radiotherapy, allows us not only to deliver higher doses to the prostate, but also to decrease the doses to the critical organs, resulting in the maintenance of patients’ quality of life within satisfactory levels. Patients’ quality of life after external beam radiotherapy is also strongly related to the total dose, fractionation regimens, dose parameters of the critical organs and treatment plan quality, with a trade‐off between the radicality of external beam radiotherapy and potentially increased toxicity. Radiation oncologists should choose treatment parameters carefully to achieve a reasonable balance between a good oncological outcome and the patient's quality of life.
