Side effects of Radiation
| The effects of radiation show up gradually. Most patients have very few initial side effects; and many patients experience fatigue during treatment. Most patients complete their radiation therapy quite easily and with very little complications. Usually side effects are experienced only in and around the radiation site. All side effects can be managed; thus, talk to your nurse or physician about this. | ![]() |
