Older adults who have Parkinson's disease and their caregivers have many concerns to take into consideration. Now, researchers from the National Institute of Environmental Health Sciences may be adding another challenge to the list. They recently published a paper in the journal Neurology, discussing the finding that the neurodegenerative illness may increase seniors' risk of developing melanoma.
This deadly form of skin cancer affects an estimated 1 in 36 individuals in the U.S., according to the Melanoma Foundation. Lead investigator Honglei Chen and her colleagues found that men who had Parkinson's disease were twice as likely to develop melanoma than their healthy counterparts, while women had one-and-a-half times the chance compared to ladies with normal cognitive function.
"Past studies linking Parkinson's disease and melanoma have not been conclusive, so we wanted to explore a larger group of studies to see whether the link was consistent," said Chen.
The authors wrote that in general, seniors with the cognitive disorder have a lower chance of acquiring smoking-related cancers. However, their increased likelihood of having melanoma may be due to the possibility that this disease shares genetic or environmental risk factors with Parkinson's. |
