I’m doing the same! DCIS but there was nothing present in the lumpectomy (removed with biopsy) so I’m passing on radiation. Not only for the side effects & residual effects but also so I have a possible option of another lumpectomy in case of reoccurrence. I am considering the AI’s since my type was ER/PR+ depending on what’s recommended with my other health issues. My Oncotype DX DCIS score came back as a 28 (in the low category) with a 6% risk with radiation & an 8% risk with just the lumpectomy. I’m willing to “roll the dice” for a 2% difference by not getting radiation.
