Major differences between male and female breast cancers uncovered but male patients still disadvantaged by lack of research, say investigators

(ECCO-the European CanCer Organisation) Male breast cancer has important biological differences from female breast cancer, according to results from a study of 1203 tumor samples from male patients. Until now it has been assumed that male patients should be treated in the same way as females, but these results mean that this is not the case, and should help doctors make better treatment choices, say the research team.
