Brief summary: This pilot clinical trial studies how well pazopanib hydrochloride works in treating patients with breast cancer that is newly diagnosed or has come back at or near the same place as the original tumor and can be removed by surgery. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by preventing the growth of new blood vessels necessary for tumor growth. Giving pazopanib hydrochloride before surgery may make the tumor smaller and reduce the amount of tissue that needs to be removed.

Detailed description: PRIMARY OBJECTIVES:

I. To determine the biologic effect, measured by a decrease in phosphorylation of vascular endothelial growth factor receptor 2 (VEGFR-2) and/or decrease in microvessel density, in breast tumor biopsies after treatment with daily oral GW786034 (pazopanib hydrochloride) for at least 12 consecutive days in early stage, operable breast cancer or local and/or regional recurrence that is amenable to surgery.

II. To determine the mechanism of antitumor effect, measured by a reduction in tumor cell proliferation (Ki67) or an increase in apoptosis in breast tumor biopsies after treatment with GW786034.

SECONDARY OBJECTIVES:

I. To determine the change in levels of tissue vascular endothelial growth factor (VEGF) in breast tumor biopsies after treatment with GW786034.

II. To evaluate the change in phosphorylation of epidermal growth factor receptor (EGFR), mitogen-activated protein kinase (MAPK), and protein kinase B (AKT) in breast tumor biopsies after treatment with GW786034.

III. To identify gene expression patterns in breast tumor biopsies before and after treatment with GW786034.

IV. To evaluate the change in VEGF (in the plasma) and VEGFR-2 (in the serum) as circulating biomarkers after treatment with GW786034.

V. To evaluate the change in circulating tumor cells in peripheral blood after treatment with GW786034.

VI. To determine whether the steady-state plasma concentration of GW786034 correlates with inhibition of phosphorylated (phospho)-VEGFR-2 and other endpoints in breast tumor biopsies.

VII. To evaluate the change in vascular permeability by dynamic contrast enhanced (DCE)-magnetic resonance imaging (MRI) of the breast after treatment with GW786034.

VIII. To compare the images obtained with bilateral DCE-MRI of the breast before, during, and after treatment with GW786034.

OUTLINE:

Patients receive pazopanib hydrochloride orally (PO) once daily (QD) for 12-20 days in the absence of disease progression or unacceptable toxicity. Patients then undergo surgical resection of tumor between days 13 and 21 (24 hours after completion of pazopanib hydrochloride).

After completion of study treatment, patients are followed up within 30 days.

Eligibility criteria: Inclusion Criteria:

* Diagnosis of invasive adenocarcinoma of the breast by core needle biopsy or limited incisional biopsy
* Tumor size \>= 1.0 cm as assessed by physical exam or radiographic exam
* Patients with histologically verified local and/or regional recurrence of invasive breast cancer that is amenable to surgery and meet all eligibility criteria may participate
* No prior chemotherapy or hormonal therapy for this primary breast cancer
* Patients who can undergo surgical treatment with either lumpectomy or mastectomy
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
* White blood cells (WBC) \>= 3,000/uL
* Platelets \>= 100,000/uL

* Prothrombin time (PT)/international normalized ratio (INR)/partial thromboplastin time (PTT) =\< 1.2 x institutional ULN
* Urine protein:creatinine ratio (UPC) of less than or equal to 1 as assessed in a random or spot urine sample
* Patients must have blood pressure (BP) no greater than 140 mmHg (systolic) and 90 mmHg (diastolic) for eligibility; initiation or adjustment of BP medication is permitted prior to study entry provided that the average of three BP readings at a visit prior to enrollment is less than 140/90 mmHg
* Eligibility of patients receiving any medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of GW786034 (pazopanib) will be determined following review of their case by the Principal Investigator
