Study links arm/hand swelling to number of lymph nodes removed during breast cancer surgery

In older breast cancer survivors, the number of lymph nodes removed during surgery and the presence of cancer in the lymph nodes were the two factors most directly linked to the development of lymphedema, swelling of the arm and hand, according to a study from the Medical College of Wisconsin's Center for Patient Care and Outcomes Research in Milwaukee, Wisconsin.

In-body stem cell therapy has enormous potential for bone injuries

Rarely will physicians use the word "miraculous" when discussing patient recoveries. But that's the very phrase orthopaedic physicians and scientists are using in upstate New York to describe their emerging stem cell research that could have a profound impact on the treatment of bone injuries. Results from preliminary work being released today, patients confined to wheelchairs were able to walk or live independently again because their broken bones finally healed.
