Radiation Questions

[ClarkA]

Hi, I have a couple questions from my wife about the radiation treatment she is about to begin. She completed TCH Chemo, had her lumpectomy surgery and is about to start IMRT Radiation treatments (28 + 7). She would like to know:

If there are any cases of just the area where the cancer was found is treated with radiation, verse using radiation on the entire breast.

Can she choose not to do radiation on the entire breast?

Are there ways to reduce the possibility of permanent color changes to the breast or skin scaring from the radiation treatments?

Is there any possibility of a change in shape or form?

Thanks!
