1 cm spot on MRI

Missmom79

ok so if any of you have been reading my threads I went for a diagnostic mammo and ultrasound on 8/12/19 and the radiologist told me that had inflammatory breast cancer. Symtoms that prompted me to go was pinkness and thickening. 8/15/19 go in for a biopsy so they can find something invasive. 10 core biopsies and only DCIS high grade 8/17/19. Went and was referred to surgeon who said they were trying to find something invasive to see what is causing my thickness shown on diagnostic mammo because the surgeon said that DCIS does not cause thickening. So on 8/23/19 I have an MRI. They seen a 1cm spot around in the area where the DCIS is. I am scheduled for another guided US biopsie on 8/26/19 this Wednesday under another guided US of the 1cm spot. My thing is if the 1cm spot turns out to be DCIS AGAIN and nothing invasive then what? Because with IBC you have to have chemo BEFORE the surgery and not the other way around. DCIS only calls for surgery and radiation correct? I just don't want them to make a mistake and treat me wrong. And I dunno why the radiologist would tell me that. You can diagnose without having cancer (invasive) under a microscope.
