I have a friend who is probably headed to radiation treatments the result of breast cancer. It appears the course will be 5 or 6 days a week for several weeks. Before I volunteer to take her to these treatments I would like to know if there is any residual effect to myself since I have a thyroid problem for which I take a daily pill.
Radiation therapy is absolutely safe and does not cause any ill effects on the relatives. Only at the time of the actual therapy being given is there a risk of radiation exposure at which time you will not be allowed with her anyway. After or before that it is not a problem, and you should definitely accompany her.
