- Non-metastatic disease
- Radiotherapy after conservative surgery with irradiation of the breast alone and complement on the operating bed (optional) completed two to six months ago
- Absence of postoperative complications
- Early radio-induced epidermis grade ≥2 (CTCAE v4.0) persistent at inclusion
- Chest circumference <120 cm and Cup <E,
- Absence of breast reconstructive surgery,
- Signature of informed consent,
- Affiliation to a social security scheme for French patients.
Group B
- Patients over 18 years old,
- Breast cancer (adenocarcinoma in situ or invasive)
- Non-metastatic disease
- Radiotherapy after conservative surgery with irradiation of the breast alone and complement on the operating bed (optional), completed two to six months ago
- Absence of postoperative complications
- Early grade 0-1 radiation-induced epidermis (CTCAE v4.0) at inclusion
- Chest circumference <120 cm and Cup <E,

Groups C, D
Patients included in the SPLICIRAD study who have formulated their agreement for the use of supernumerary samples at the time of inclusion:
- 10 patients with late pathologic radio-induced fibrosis (more than 6 months after the end of radiotherapy), grade CTCAE v4.0 ≥ 3 vs.
- 10 patients without late pathological radio-induced fibrosis of grade CTCAE v4.0 ≤ 1 (follow-up after RT ≥4 years)
Group E Patients over 18 who have given their consent to the Blood Establishment for the use of their samples for research purposes.
Non-inclusion criteria for groups A, B, C, D:
- Systemic inflammatory disease associated with individual radiosensitivity
- Dermatological pathology in the breast
- Radiotherapy having delivered an overdose> 107% of the prescribed dose in at least 10% of the PTV
- Diabetes
- Active smoking
- Chronic systemic anti-inflammatory therapy, immunotherapy, immunosuppressants, anti-TNF
