Large lump and rednesss

Hi 

I have a large lump left boob inside I think it’s called lower quadrant on insode

my skin is red and inflamed on top of it

i had a mammogram yesterday that said it aired on middle of concern

so then had infrasound and biopsy

she said ultrasound kicked up more concer, she is talking like I already have cancer and said more likely than not

inwas hoping it may be an infected fibrodenma 

doe she no or could it still be good news c
