Breast Cancer

About this trial
This is an interventional supportive care trial for Breast Cancer focused on measuring stage I breast cancer, stage II breast cancer, invasive ductal breast carcinoma, medullary ductal breast carcinoma with lymphocytic infiltrate, mucinous ductal breast carcinoma, tubular ductal breast carcinoma, papillary ductal breast carcinoma
Eligibility Criteria

- 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 skin involvement of disease
- No Paget's disease of the nipple
- No distant metastatic disease
- Hormone-receptor status not specified
