In brief: Size nodes
We recommend radiation after mastectomy if the tumor is large (greater than 5 cm), involves muscle or skin, or if lymph nodes are involved.
The data in support of XRT are very strong if 4 or more nodes are involved - decreses local recurrence and improves survival. The benefits are debatable if only 1 or 2 nodes are involved, but still recommendede by most experts.

In brief: Margins clear does
Not prove every cancer cell is gone.
The issue varies with type and size of the tumor, in situ or invasive cancer. Some are investigating treatment to partial breast, shorter courses, and special equipment (mammosite, cyberknife). Whole breat raiotherapy is time and data suppoted. If tumor recurs in a breast, the owner is likely to lose it.
