Biopsy for Breast Cancer, feeling anxious!

Hi, 

I came home today after having a mammogram, ultrasound and biopsy. Originally, I was diagnosed with mastitis in the right breast, the redness and pain went but a lump remained (btw im 36 and have no children).So I was given an urgent referral to the breast clinic. 

 

During the ultrasound, the radiologist said she was worried and found calcification in my right breast, she also noticed a small lump in armpit.  She sent me for a mammogram and then did a biopsy. 

I met with the consultant and he did a physical examination and said the lumps were movable which is a good sign but he said there's an 80% chance of it being breast cancer due to the calcifications and lump in armpit.

I feel so anxious and sick. Everytime I try to sleep image's of the hospital keep coming to mind. 

Has anyone been the same position where a consultant has given an inkling to what it is? Is there a chance he could be wrong?
