Survivor since 2009
I had invasive ductile carcinoma (IDC) stage 2B ER/PR+ and HER-2 NEG. I had a mastectomy, so there was no reason for radiation, but I had to have chemo. My oncologist told me that after the mastectomy and the chemo, I had a 15% chance of recurrence. So, I would assume with DCIS it is probably much less, because DCIS is not invasive. I am no doctor, but that is just my assumption from what my case is. You should probably ask your oncologist for statistics like that. Good luck to you and God bless!
