Mastitis, IBC or something else?!

So I went to the GP 10 days ago with a small lump under my nipple, just next to where I had a benign tumour removed in 2009. He referred me to the breast clinic, and over the week that small lump turned into a HUGE (orange sized) hardness encompassing my nipple and a triangular wedge shape in my under boob. He put me on antibiotics for lactational mastitis (I’ve not breastfed in 2 years) and after 5 days of no improvement I went back yesterday to have the antibiotics changed. 
I’ve got the clinic on Saturday but I’m absolutely freaking out.

I had a heart condition diagnosed in May so I’m scared that it was the precursor to something horrible?! But I don’t see how it would have grown this much in 10 days…?! Also I had 3 CT scans when I was getting my heart diagnosed, the most recent one was about 6 weeks ago, could a tumour have appeared so fast?

I’m noticing swelling after I take my bra off, like a fluid pooling kind of thing…

Also a little warmth in the hard area. But no rash, itching, oozing etc. 

Has anyone had these symptoms before with a positive outcome?

  • So it’s not great news.
    I had a mammogram and an ultrasound, it’s not cysts or mastitis, and I have some angry areas in my armpit as well as all the boob lumpiness, which I’ve had biopsies on.
    The nurse said we won’t know for certain until the biopsy results come back, but it’s looking like it could be inflammatory breast cancer. We won’t know for certain for a week or so though.
