- Will has just been diagnosed with melanoma on the anteromedial surface of his thigh. Melanoma is the most dangerous form of skin cancer, in large part because it tends to spread through the body (metastasize) fairly quickly. To determine if Will’s cancer has metastasized, Will’s doctor takes a sample of tissue from his lymph nodes and looks for the presence of cancer cells. If cancer cells are found in the lymph nodes, Will may have some lymph nodes surgically removed. Will’s doctor warns him that he may experience uncomfortable swelling in his leg if this happens A) Explain why Will’s doctor is looking at the inguinal lymph nodes first to determine if the melanoma has spread. (A complete answer will include an explanation of why the ymph nodes and why these lymph nodes in particular.)
