Does cancer cause itchy scalp? My mother-in-law is receiving treatment for cancer eg chemo. She iis over 85 years of age and has been doing fine at first, however she is ever so itchy. All over and nothing seems to help. I read you article on "itchy scalp" and treatment. Could this also be due to the steroid that she is taking? And what can she do to relieve it? Nothing has helped so far. Thank you kindly. Pippa
