Scientists find stem cells in human breast cancer

Of all the neoplastic cells in human breast cancers, only a small minority – perhaps as few as one in 100 – appear to be capable of forming new malignant tumors, according to just-published research by scientists in the University of Michigan Comprehensive Cancer Center. The discovery could help researchers zero in on the most dangerous cancer cells to develop new, more effective treatments.

Detection procedure can help more melanoma patients than thought

Patients who develop melanoma on their face, head or neck can have the same early-diagnosis surgical procedure to see if their cancer might spread as patients whose cancer is on less delicate areas of the body, a new study finds. The report, from a team at the University of Michigan Comprehensive Cancer Center, opens the door for many more melanoma patients to benefit from a potentially life-saving technique called sentinel lymph node mapping. The results will be published in the Archives of Otolaryngology, a journal of the American Medical Association.
