- description
- For all patients, the NovaGray RILA Breast® test will be performed between day -30 and until the first day of radiotherapy (before the start of this one) and then 12 months after the end of radiotherapy and in the case of neoadjuvant chemotherapy, between day -30 and until the first day of chemotherapy (before any injection) and in the case of adjuvant chemotherapy, between day -30 and until the first day of chemotherapy (before any injection). The test consists of a blood sample of 2x4 mL
