Study population: Study population include female Chinese breast cancer patients who wish to undergo autologous or prosthetic-based breast reconstruction.

Brief summary: The purpose of the study is to investigate the impacts of radiation and the timing of radiation on autologous and prosthetic-based breast reconstruction in Chinese post-mastectomy breast cancer patients. The study aims to optimize the timing for autologous/prosthetic breast reconstruction which delivers the best aesthetic results while maintains low complication rate and best integrates into the comprehensive breast cancer treatment. The study is open to all female breast cancer patients undergoing breast reconstruction in the department of breast reconstruction in Tianjin medical university cancer institute and hospital.

Detailed description: In breast cancer patients, post-operative radiation therapy is an important component in breast cancer management. However, in the context of breast reconstruction, radiation can have adverse effect as it increases the rate of fat necrosis and leads to fibrosis/ capsular contracture in the reconstructed breast mounds. It is therefore necessary to investigate the best timing for breast reconstruction, especially in those patients which post-operative radiation is required, which does not interfere with overall breast cancer treatment while produces the best surgical, aesthetic and psychological outcome. Most studies in this field are retrospective, and studies on Chinese cohort are also rare. This multi-center prospectively designed clinical trial will include several medical centers across China. The investigators will allocate the patients into three arms based on the status and sequence of radiation and breast reconstruction, and will further stratify the groups based on the different approaches of reconstruction (autologous/ prosthetic based). Both objective and subjective (patient oriented) methods will be employed to make evaluations involving surgical, aesthetic, and psychological outcomes.

Eligibility criteria: Inclusion Criteria:

* Diagnosed with breast cancer
* Karnofsky Performance Status (KPS) larger than 70
* Underwent autologous or prosthetic based breast reconstruction
* No severe deficiency in hematological, cardiovascular system, no immune-deficiency, no severe abnormal liver or kidney function.

Exclusion Criteria:

* Metastatic breast cancer
* Local recurrence after mastectomy
* Prior radiation history to chest wall due to other tumors
* Radiation performed more than 6 months after mastectomy
* Interruption of radiation more than 2 weeks
* Gravida or during lactation
* Concurrently undergoing psychotic disorders

Primary outcomes:
measure: occurrence of short term complications
timeFrame: the short term complications will be inspected up to 3 months post-op;
measure: occurrence and change of long term complications
timeFrame: the long term complications will be assessed at 6 months post-op; repeated assessments will be made at 12 and 24 months to record changes
measure: occurrence of secondary surgery
timeFrame: up to 24 months post-op
Secondary outcomes:
measure: occurrence of revision surgery
timeFrame: 6 to 24 months post-op
measure: baseline and change of subjective evaluation
timeFrame: the baseline evaluation will be made at 6 months post-op; repeated evaluations will be made at 12 and 24 months to record changes
