We proceed with development and clinical application of new modalities of breast imaging; portable microwave breast tumor detector and ring-type dedicated breast PET.
Basic research is focusing on the growth pathway of hormone-positive breast cancer and the functional subpopulation of tumor-infiltrating lymphocytes.
