DCIS Survivor Just Diagnosed with IDC

Well, here I go for round 2. Found out I have Invasive Ductal Carcinoma Grade 2, ER 3+, Pr 3+, HER 2 neg, Ki67 is 20%, P63 negative, Ecad positive through biopsy after getting a call back on my mammogram. How do I know if this us recurrent or new primary? My DCIS was at 6:00 and I had lumpectomy and radiation in 2000. The IDC is at 9:00 adjacent to lumpectomy site.

Already got a call from surgeon and go next week. Guess I will be moving over to the other board.
