Chemotherapy and Cancer Gang up to Cause a Neurological Side Effect, Study Says

Contrary to common medical guidance, chemotherapy does not appear to be the only culprit in neuropathy, a neurological side effect of cancer treatment, a new study says. Cancer itself contributes heavily, too, and the stresses on neurons appear far worse than the sum of the two causes. “There was some distress caused […]
