The goal of the study is to investigate the feasibility of enabling a second chance for breast conservation in patients with in-breast recurrences after a previous lumpectomy and RT, investigators propose to test partial breast irradiation with the target volume encompassing the entire surgical bed with 1.0-1.5 cm margins.
An additional goal of the study is to investigate the feasibility of enabling a second chance for breast conservation in patients with inbreast recurrences after a previous lumpectomy and PBI, the investigators propose to test whole breast RT (WBRT) with the target as the whole breast volume.
Patients will be treated with the fractionation of 30 Gy in 5 fractions over 1-2 weeks, which is the accelerated fractionation scheme of choice for Radiation Therapy (RT) naïve patients at New York Presbyterian using EBRT or with the fractionation of 4050 cGy in 15 fractions over 3 weeks, based on the previous treatment that they received.
The main aim of the study is to evaluate the rate of early grade 3 toxicities with this approach.

This count of participants will include patients who experience the following: skin hyperpigmentation, fibrosis, telangiectasia, skin induration and edema. |
| baseline, approx. week 1- week 2 of radiation, 6 months, 12 months, 24 months, 36 months, 48 months, 60 months. |
| Change in Quality of life as assessed by Breast Cancer treatment outcome scale (BCTOS) | The Breast Cancer Treatment Outcomes Scale (BCTOS) will be used to evaluate patient-reported cosmetic outcome, functional status, and breast pain. Each BCTOS subscale (cosmetic, functional status, and breast pain) is calculated by computing the arithmetic mean of the answers to each item relevant to a given subscale. The score is a continuous variable ranging from 1 to 4, with 1 indicating no difference between the treated and untreated breast, 2 indicating a slight difference, 3 indicating a moderate difference, and 4 indicating a large difference. Participants completing the BCTOS is optional. | baseline, approx. week 1- week 2 of radiation, 6 months, 12 months, 24 months, 36 months, 48 months, 60 months. |
| Number of participants who demonstrate local control | Patients will be followed for recurrence of cancer in the treated breast. | 60 months |
