If re-excision results in negative surgical margins 0.2 cm or more, patient is eligible.\n* If image guidance with daily cone beam CT with direct physician visual assessment is used for treatment positioning, the presence of markers or clips in the surgical bed is recommended but not required. If cone beam CT imaging will NOT be used for image guidance, then the patient must be prepared to have 2 fiducial markers minimum, 3 preferred, placed prior to treatment (if not previously done).\n\n  * If markers or clips were placed at the time of surgery, patient must be able to start treatment within 12 weeks after lumpectomy or re-excision for adequate margins.\n  * If markers were not placed at the time of surgery and are needed, patient must have markers placed within 6 weeks after surgery.\n  * If systemic chemotherapy was given, patient must have had clips or markers placed at the time of surgery (if they are needed) and patient must have simulation scans within 6 weeks of the completion of the chemotherapy.\n* Must be able to start treatment within 12 weeks of surgery or 8 weeks of finalization of chemotherapy.\n\nExclusion Criteria:\n\n* Previous history of ipsilateral invasive breast cancer or DCIS.\n* Any clinical or radiographically suspicious nodes, unless biopsy proven benign.\n* Non-epithelial malignancies such as sarcoma or lymphoma.\n* Suspicious residual microcalcifications on mammography of either breast, unless negative for malignancy on pathology.\n* Multicentric or bilateral disease unless biopsy of the clinical abnormalities are performed and result is negative.\n* Lymphovascular space invasion (LVSI) on pathology specimen.\n* Any previously treated breast carcinoma or synchronous breast carcinoma in ipsilateral breast.\n* Prior radiation therapy to the ipsilateral breast or thorax.\n* Paget's disease of the nipple.\n* Histologic examination showing invasive lobular histology.\n* Skin involvement.\n* Breasts technically unsatisfactory for radiation treatment upon the discretion of the treating physician.\n* Significant infection or other co-existing medical condition that would preclude protocol therapy such as pregnancy, HIV\u002FAIDS or collagen vascular diseases specifically systemic lupus erythematosus, scleroderma, or dermatomyositis.\n* Known BRCA 1 or BRCA 2 mutation.\n* Pregnant or lactating.","FEMALE","50 Years",{"count":193,"type":194},132,"ESTIMATED","INTERVENTIONAL",[197],"PHASE2","The purpose of this research study is to compare the effects (good and bad) on women and their cancer using proton radiation therapy.\n\nThis study is being done to see if proton radiation therapy will prove to be beneficial for women with early stage breast cancer.
