Summary
Brief summary (as posted)
RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: This clinical trial is studying how well partial breast radiation therapy works in treating women undergoing breast-conserving therapy for early stage breast cancer.

* Lesion ≤ 3 cm
* No more than 3 positive lymph nodes
* Patients with 4 or more positive axillary lymph nodes found at the time of axillary lymph node dissection/sentinel lymph node biopsy are not eligible
* Has undergone tylectomy (lumpectomy) and axillary lymph node sampling (axillary node dissection or sentinel node biopsy)
* Negative resection margins with ≥ 2 mm margin from invasive or in situ cancer OR a negative re-excision margin
* Unifocal breast cancer
* No multicentric carcinoma (tumors in different quadrants of the breast or tumors separated by ≥ 4 cm)
* No palpable or radiographically suspicious contralateral axillary, ipsilateral or contralateral supraclavicular, infraclavicular, or internal mammary lymph nodes unless these are histologically confirmed negative

* No collagen vascular disorders, specifically systemic lupus erythematosus, scleroderma, or dermatomyositis
* No psychiatric, neurologic, or addictive disorders that would preclude obtaining informed consent
* No other malignancy within the past 5 years, except non-melanomatous skin cancer
PRIOR CONCURRENT THERAPY:
