Breast fat grafting and cancer: a systematic review of the science behind enhancements and concerns.

Background: Autologous fat transfer (AFT) is gaining popularity in breast surgery, offering a natural-looking and minimally invasive approach for augmentation, reconstruction, and contouring. However, concerns about its impact on breast cancer necessitate an understanding of the interplay between transplanted adipose-derived stem cells (ADSCs) and the breast tissue microenvironment. Renowned for regeneration, ADSCs raise questions about their role in cancer promotion.

Hyperbaric oxygen therapy: types of injury and number of sessions--a review of 1506 cases.

Objective: The aim of this work was to identify clinical data indicative of the number of hyperbaric oxygen therapy HBO2 sessions that should be prescribed for adjuvant treatment of tissue injuries of differing severity.

Patients: A total of 1730 cases of patients treated with HBO2 using an open protocol (without a predetermined number of sessions) was examined in this study.

Method: A retrospective study involving charts review was conducted.
