Fast growing Breast Cancer

had a breast cancer scare 5 years ago. I had all the tests; mammograms, scans & lots of biopsies on my left breast. At the time I was told it was just cysts & discharged. 2 years later I had a negative mammogram.

My next routine mammogram is due next month. However I felt a hard area in my left breast and have just come home from the breast clinic.

I have been advised that I probably have breast cancer as the mammogram & scan have shown a suspicious mass of about 5cm. I'm now waiting for biopsy results (they also took a sample from a lymph node under my armpit )

I'm worried sick.

Has anyone else experienced such a fast growing tumor. How come it didn't show up on my last mammograms? I've never missed one.
