I am also stage I grade 3 her2+. Is your friend ER/PR negative or positive and were her nodes negative or positive? The answers to these questions can make a difference in treatment. I was node negative and er/pr negative. I had 12 weeks of AC and 6 1/2 weeks of radiation. The last nine radiation treatments were what they call a booster directly to the site of the tumor. I started herceptin in early September and will continue if all goes well for a year. I wish your friend the best. Once she is done with chemo the rest is easy.

Her2+ er/pr- Stage I Grade 3 tumor size 1.4 cm, node negative
