There is a commercial currently running to advertise Cancer Centers of America in which a woman states that she had to quit exercising because she developed itching, and that was a symptom indicative of advanced stage breast cancer. However, the advertisement doesn't elaborate on her symptomatic itch, and I have been unable to find information to correlate her claims. No mention was made as to whether her itch was a result of sun-related damage. Anyone know where I can find further info on this issue? Thanks.
