Donor immune cells attack metastatic breast cancer

In patients with metastatic breast cancer, immune cells from a genetically matched donor can attack and shrink tumors, researchers from the National Cancer Institute (NCI) announced today at the Annual Meeting of the American Society of Clinical Oncology in Chicago. This is the first time researchers have clearly demonstrated this type of immune response, known as a graft-versus-tumor effect, acting against breast cancer.

Men don’t recognize their breast cancer until a late stage

Breast cancer in men is usually detected when the tumors are bigger, have spread and may be more aggressive, compared to diagnosis of the disease in women, concludes the largest study ever conducted of male breast cancer. The findings, presented at the annual meeting of the American Society of Clinical Oncology, suggest both that breast cancer in men may have some important biological differences from the female disease, and that men are seemingly less aware than they should be that they can develop breast cancer.
