ARM 1 Daily Boost
Radiation Therapy 15 daily radiation fractions of 2.7 Gy, Monday to Friday for 3 weeks, to the whole breast with a daily concomitant boost of 0.5 Gy to the tumor bed, for a total daily dose of 3.2 Gy to the tumor bed (2.7Gy+0.5 Gy). The overall dose will be 40.5 Gy to the breast and 48.0 Gy to the tumor bed.
ARM 2 Weekly Boost
Radiation Therapy 15 weekly radiation fractions of 2.7 Gy Monday to friday for three weeks to the entire breast with a Friday boost of 2.0 Gy to the tumor bed, for a total dose to the tumor bed on each friday of 4.7 Gy (2.7 Gy+ 2.0 Gy). The overall dose will be 40.5 Gy to the breast and 46.5 gy to the tumor bed.

SECONDARY outcome

Timeframe: Baseline

BCTOS is a validated questionnaire designed to measure breast esthetic and function after breast-conservations treatment. Patients rate the difference between their untreated and treated breast in 3 categories. There are 4 score levels: 1 = "No difference"; 2 = "Slight"; 3 = "Moderate"; 4 = "Large difference". The total range is 3-12; the lower the score the lower the difference between the untreated and treated breast.

SF-36 is an extensively used questionnaire designed to compare health status across various populations and is commonly used in cancer trials Our survey includes the portion of the SF-36 focused on the assessment of patient fatigue, or "vitality," at various stages of treatment Example question: How much of the time during the past 4 weeks did you feel full of life? (Answer on scale 1 to 5). 1 = "All of the time"; 2 = "Most of the time"; 3 = "Some of the time"; 4 = "A little of the time"; 5 = "None of the time".
