How prostate cancer packs a punchSome types of prostate tumors are more aggressive and more likely to metastasize than others. Nearly one-third of these aggressive tumors contain a small nest of particularly dangerous cells known as neuroendocrine-type cells. More rarely, some aggressive prostate tumors are made up entirely of neuroendocrine-type cells. The presence of neuroendocrine-type cancer cells is linked to a poor prognosis, but spotting these rare cells can be like........Go to the Prostate-cancer-blog (Added on 7/13/2010 7:23:43 AM)
