Relative c-Src activity in non-recurrent versus recurrent lobular breast cancer (LBC) patients. The box plot shows the increase in active c-Src fluorescence of invasive lobular carcinomas (ILCs) relative to their adjacent in situ lesions in the groups of patients with nonrelapsed (NR) and relapsed (R) disease. The median value is indicated by the lines across the boxes. Box lengths refer to the interquartile range. Lower and upper whiskers represent the minimal and maximal values, respectively.
