The National Cancer Institute estimates that 238,590 new cases of prostate cancer will be diagnosed in 2013, and 29,720 men will die from the disease, reports Science Daily. The study was led by stem-cell expert Paul Frenette, professor of medicine and of cell biology and director of the Ruth l. and David S. Gottesman Institute for Stem Cell and Regenerative Medicine Research at Einstein. Nerves are commonly found around tumours, but their role in the growth and progression of cancer has not been clear.
