Summary
Brief summary (as posted)
RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erlotinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well erlotinib works in treating patients with breast cancer that can be removed by surgery.

Inclusion Criteria:
* Clinical stage I or II (T1 or T2, N0 or N1) invasive mammary carcinoma
* Diagnosis may be made by fine needle aspiration cytology or core biopsy

* Measurable residual tumor at the primary site
* Measurable disease is defined as any mass that can be reproducibly measured by physical examination
* Planning to undergo surgical treatment with either segmental resection or total mastectomy

* Not pregnant or nursing
* Negative pregnancy test
* Fertile patients must use effective contraception
* No serious medical illness that, in the judgement of the treating physician, places the patient at high risk of operative mortality
PRIOR CONCURRENT THERAPY:
