The presence of cancer-associated fibroblast in breast cavity side margins is in correlation with the expression of oncoproteins by adjacent epithelial cells: a new era in cancerous potential

The presence of CAFs is correlated with the presence of high glycolytic metabolism in the cavity margin lesion, high ROS level in the lesion, and finally aggressive cancer-associated proteins (such as MMP2, …) in the margin while these metabolomes, molecules, and proteins are absent in the margins with negatively scored CDP response and low ROS level. So, it seems that when we observe CAFs in glycolytic lesions with high ROS levels, some high-risk epithelial breast cells may exist while no histological trace of cancer cells was observed. Further research on CAFs could provide valuable insights into the local recurrence of malignant breast diseases. Hence, real-time sensors can be used to detect and investigate CAFs in the non-tumoral regions surrounding tumors in cancer patients, potentially aiding in the prevention of cancer recurrence.
