Superficial spreading melanoma is a type of skin cancer that slowly grows horizontally across the top layer of skin before moving to the deeper layers. It’s the most common form of melanoma, accounting for 70 percent of all cases. While it’s uncommon in children, superficial spreading melanoma can affect people of all ages, even in areas of the body that see little sun.
