experience with aggressive HER2 cancer

[olganyc]

Dear Ladies,
I was diagnosed with HER 2 positive breast cancer in September 2013, with a 2 cm lesion.
On October 25, the mass measured 3 cm and they detected two new masses
On November 15, the mass is 4.5 cm

my breast surgeon said this rapid growth is unusual.

Did you have experience with such aggressive form of breast and ca and what is the best way to approach is? Chemo first? which kind? Or surgery first?

thank you
Olga
