Summary
Brief summary (as posted)
RATIONALE: Breast-conserving surgery is a less invasive type of surgery for breast cancer and may have fewer side effects and improve recovery. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II clinical trial is studying how well breast-conserving surgery followed by radiation therapy works in treating patients with stage I or stage II breast cancer.

Inclusion * Patients with multicentric carcinoma (tumors in different quadrants of the breast or tumors separated by at least 4 cm) * All radiographically suspicious lesions must be biopsied and have histologically confirmed ductal carcinoma in-situ, invasive ductal, invasive lobular, medullary, papillary, colloid (mucinous), or tubular histologies * A maximum of two radiographically detected malignant lesions * Clinical Stage I-II breast carcinoma, with lesion size =\< 5 cm for the dominant mass and the second lesion detected only on MRI, treated with lumpectomies; the MRI detected lesion must be pathologically =\< 1 cm * Axillary lymph node evaluation, either sentinel lymph node biopsy or axillary dissection as deemed appropriate by the treating surgeon for all patients with invasive cancer; no axillary lymph node sampling is needed for patients with DCIS * Negative resection margins with at least a 2 mm margin from invasive and in-situ cancer or a negative re-excision * A posterior margin =\< 2 mm from DCIS is permissible provided fascia was taken * Patients are eligible regardless of estrogen receptor, progesterone receptor, or Her-2/neu amplification * Hormonal therapy is allowed; if adjuvant chemotherapy is planned, the chemotherapy should be delivered first and radiation must begin no earlier than three weeks and no later than eight weeks following completion of chemotherapy * Signed study-specific informed consent prior to study entry Exclusion * Extensive intraductal component by the Harvard definition (i.e., more than 25% of the invasive tumor is DCIS and DCIS present in adjacent breast tissue) * Palpable or radiographically suspicious contralateral axillary, ipsilateral or contralateral supraclavicular, infraclavicular, or internal mammary lymph nodes unless these are histologically confirmed negative * Patients receiving neoadjuvant chemotherapy * Patients with distant metastatic disease detected by radiographic imaging; specific studies for systemic imaging should be obtained as directed by localized symptoms or per available NCCN guidelines * Patients with known BRCA 1/BRCA 2 mutations or those with predicted risk of carrying the mutation by BRCAPRO (44) risk assessment \>= 50% * Diffuse calcifications throughout the breast * Patients with skin involvement or inflammatory breast cancer * Patients with Paget's disease of the nipple * Patients nonepithelial breast malignancies such as lymphoma or sarcoma * Patients with collagen vascular disorders, specifically systemic lupus erythematosis, scleroderma, or dermatomyositis * Patients with psychiatric, neurologic, or addictive disorders that would preclude obtaining informed consent * Other malignancy, except non-melanomatous skin cancer, \< 5 years prior to participation in this study * Patients who are pregnant or lactating, due to potential fetal exposure to radiation and unknown effects of radiation on lactating females
