I chose not to have radiation. The radiation offered was very precise and site-specific. The radiologist explained that it was similar to sweeping up the floor around where one had dropped a glass that broke. In a sense it was to pick up stray cancer cells in the immediate vicinity of the cancer that was removed. The radiologist explained that it would not for example kill cancer cells in another part of the same breast even. I had a good surgeon and the pathology reports noted clean margins and the OncotypeDX result showed a very low, single digit risk of recurrence. So I passed on the radiation that was, again, suggested as as just an option. My thinking also was affected by the fact that the cancer was in the left breast so closer to the heart.
