Often melanomas grow and spread horizontally on the top layer of the skin before penetrating deeper into the layers of the dermis. There they can reach the lymph and blood vessels. Lymph vessels are not only a pathway, however. Researchers have uncovered a unique mechanism whereby the direct contact with lymphatic endothelial cells promotes melanoma metastasis – also called Stage IV melanoma where the cancer cells have spread through the lymph nodes to distant sites in the body, the most often affected being liver, lungs, bones and brain.

The lymph vessel endothelial cells play an active role in the spread of melanoma, according to the new study conducted at the University of Helsinki.
