However, recurrence is most common and most of the patients do not develop a satisfactory immunological antitumour response due to several mechanism, T-cells dysfunction. It is about 1% in men. In present study, we tried to investigate the role of T-cells and DNA content analysis as prognostic marker in breast cancer patients compared to normal healthy individuals using Flowctometry and Confocal Laser Scanning Microcopy. We studied 31 Breast carcinoma patients and 12 Normal healthy persons. Out of 31 patients, cancer patients showed significant increase in CD3, CD4 percentage while there was no significant change in CD8 percentage.
