Using a needle biopsy technique, skeletal muscle tissue was harvested, stem cells isolated and expanded in vitro, and then implanted in patients using a transurethral or periurethral technique. No adverse events or safety issues were identified in the population. ...Breast MRI may help determine surgical management of women with newly diagnosed breast cancer

In the study, the researchers analyzed data on more than 1,100 men who underwent surgery between 1996 and 2005 to remove the prostate gland, a common treatment for prostate cancer. They compared th...Rhode Island Hospital study confirms RF ablation effective for treating inoperable lung cancer
