Overall goal of the project: To determine HER2 expression level in primary breast cancer before neoadjuvant system therapy (chemotherapy or/and targeted therapy).
Phase I. Distribution of \[99mTc\]Tc-G3-(G3S)3C in patients with primary breast cancer. The study should evaluate distribution of \[99mTc\]Tc-G3-(G3S)3C in patients with primary HER2-positive and HER2-negative breast cancer.

Not accepted
You may be eligible if
1. Subject is \> 18 years of age
2. Availability of results from HER2 status previously determined on material from the primary tumor and metastatic LN, either a. HER2-positive, defined as a DAKO HercepTest™ score of 3+ or FISH positive or b. HER2-negative, defined as a DAKO HercepTest™ score of 0 or 1+; or else if 2+ then FISH negative
3. Hematological, liver and renal function test results within the following limits:
* White blood cell count: \> 2.0 x 109/L
