Parkinson's disease and prostate cancerUniversity of Utah School of Medicine scientists have found compelling evidence that Parkinson's disease is linked to an increased risk of prostate cancer and melanoma, and that this increased cancer risk also extends to close and distant relatives of individuals with Parkinson's disease.

For Breast Cancer Patients Fatigue is RealThe persistent fatigue that plagues one out of every three breast cancer survivors appears to be caused by one part of the autonomic nervous system running in overdrive, while the other part fails to slow it down.
That imbalance of a natural system in the body appears associated with the tiredness and exhaustion that can burden cancer patients as much as a decade after their successful therapy.
