This hypothesis is partially
supported by studies that indicate that the greatest rise in
melanoma has occurred in nations where chemical sunscreens are heavily promoted and used.
Based on the pioneering work of Dr. Claire Lugassy and Dr. Raymond Barnhill at UCLA's Jonsson Comprehensive Cancer Center, a new study provides additional
support for a process
by which
melanoma cells, a deadly form of skin cancer, can spread throughout the body
by creeping like tiny spiders along the outside of blood vessels without ever entering the blood stream, and that this process is exacerbated
by exposure to ultraviolet (UV) light.
