How a patient feels during radiation therapy is highly individual. Many people are able to continue working throughout radiotherapy, feeling well enough to carry on with all usual activities. Others may need to decrease their work hours or take time off.
In case you were wondering, radiation therapy does not cause you to become radioactive. There is no lingering radiation after your treatment, and you can be around friends and family. If you are undergoing brachytherapy, your doctor will review any specific guidelines with you.
